Foreword
As a technical association with a long tradition,
the DVGW has been synonymous with quality,
environmental protection and hygiene in German gas and water supplies for 150 years. Since
it was established in 1859, the association has
played a key role in the systematic development
of gas and water supply systems in Germany.
The work of a technical and scientific association
is always something of a balancing act between
the maintenance of successful methods and
practices on the one hand and the need for a
forward-looking approach and innovation on
the other hand. The 150-year history of the
DVGW and technological developments in
the gas and water sectors clearly demonstrate
that the DVGW, with its technical committees
working on a voluntary basis, has always been
quick to welcome new technologies and developments. At the same time, the association has
always taken account of the associated risks,
analysed them and assessed them by adopting
a holistic and rational approach. These aspects
are the strengths that characterize the DVGW
as an impartial technical standardization body,
have defined the work of the association in its
anniversary year and will continue to apply in
the future.
The work of the DVGW in its anniversary year
focused on efficiency and innovation as well as
on the conservation of resources. All in all, the
DVGW was once again able to play a key role in
this area and to deliver significant added value
for the entire gas and water industry.
This achievement was only possible as a result of
the considerable dedication of the volunteers on
our technical committees, our extensive network of experts and the confidence placed in the
association by the relevant authorities. Sincere
thanks are due to everyone concerned for their
support.
This Annual Report gives an overview of our
achievements in 2009.

The 150th anniversary of the DVGW (1859 – 2009) attracted
considerable interest. One of the highlights of the anniversary year was the outstanding anniversary conference in Leipzig, which profoundly moved the participants and prepared
them for the work ahead. The anniversary festschrift, entitled
Elemente, die bewegen. Mensch und Technik im Gas- und
Wasserfach (“Moving elements – people and technology
in the gas and water sector”) also left a lasting impression
with its comprehensive and fascinating presentation of the
history of the association and technology and a section with
photographs of high artistic quality. The photographs were
the work of Berlin photographer Roland Horn, who travelled
about 30,000 kilometres throughout Germany to capture
images of people in the gas and water industries at their daily
work on behalf of the DVGW. This Annual Report gives a
glimpse of this unparalleled campaign, with excerpts from
all the photo session which took place. It is also intended as
a token of our gratitude to all the sponsors (see list of photo
sources on page 49). If you would like to take a look at the
festschrift, it is available (unfortunately only in German) for
downloading at www.150-jahre-dvgw.de, where you can also
order a printed copy.

Gas and water on the move
The uniform codes of practice issued by the
DVGW make work easier for public bodies, gas
and water companies, contractors and industry.
The state defines the objectives of standardization and these are then fleshed out by the drafting and responsible application of DVGW codes
of practice. For 150 years, the DVGW has been
a reliable partner for its members, authorities,
government and above all consumers for whom
water and gas are essential for their everyday
lives.

150 years of safety, hygiene and environmental protection
The DVGW has been active in the gas and
water industry for 150 years. Its activities
can be traced from the issue of technical
standards on safe gas production and use
and hygienic water supplies in the 19th
century through to its instrumental role in
the reconstruction of German water supply
systems following the Second World War,
the shaping of modern natural gas systems in
the 1960s and 1970s, including the successful changeover from town gas to natural gas
in the states of eastern Germany following
German unification, to the issues which are
most important today. Apart from standardization, the DVGW has always focused
on research and development; in addition,
inspection and certification, and professional
development and qualification have become
increasingly important.
In 2009, the activities of the DVGW once
again focused on current challenges,
especially on the liberalization of energy
markets, the modernization debate in the
water industry and increasingly climate
protection and its implications.

Fostering innovative gas application technology
The mitigation of climate change calls for considerable efforts at all
stages in energy conversion and use including local energy supply. As
the technical and scientific association of the German gas and water
industry, the DVGW has launched a gas technology innovation campaign with a view to laying the technical foundations for this process
of fundamental change by targeted research and support for innovative technologies. The campaign focuses on the major ecological and
technical potential of public gas supply systems and the sustainable
use of existing infrastructure.
In the first stage of the campaign, a study conducted by the Swiss
Prognos institute concerning the innovation potential of gas technology was presented. The study shows that innovative gas technologies
meet the new climate policy requirements in their entirety. The key
to future success will be a combination of gas and renewable energy
sources and the use of highly efficient technologies. The innovation
campaign was launched at the Anniversary Conference in September
2009. Up to 2011, some six million euros are to be made available for
various research projects aimed at improving the energy efficiency of
existing systems and developing highly promising new approaches.
The main focus of DVGW activities will be on further efficiency
improvements as well as focused information for multipliers from
politics, industry and the installation trade.

Benchmarking: comparability criteria for water companies
In view of the wide variety of factors affecting each individual water
company, it is not possible simply to assess companies and their services solely on the basis of one parameter, such as the water price. The
main reasons are:
•The different conditions faced by local authorities and state
governments
•Differences in the interpretation of the requirements of the
competent health and water authorities
•Different levels of capital spending
•Different wishes of consumers (e.g. wishes for central water
softening plants)
•Different structural conditions, with respect to the natural
environment, raw water contamination, settlement and consumer structures
Individual water companies must design, construct and operate their
systems in such a way that they can always react to external conditions and ensure security of supplies (a round-the-clock supply of
water at adequate pressure) and safe and hygienic drinking water.
To allow a transparent, fair comparison of service levels, the DVGW
is currently developing a procedure for characterizing and comparing
the structural conditions faced by water supply systems. The objective
is to lay the technical and scientific foundations for structural comparisons of the main water supply processes taking into consideration the five main characteristics of safety, quality, customer service,
sustainability and economics in water supply.
identifies quality requirements and ensures
compliance at the same time as covering
safety requirements.
In 2009, the DVGW TSM manual for selfassessment was revised and adapted to reflect
current developments in the industry. In addition, preparations were made for expanding the range of services:
• A TSM system for LPG plants supplying local distribution networks was developed in cooperation with Deutscher Verband Flüssiggas e.V. (DVFG).
• In response to the initiative of state energy
regulatory authorities, the DVGW is
developing, in cooperation with Fachver band Biogas e.V., a TSM system for biogas plant operators covering systems from the production plant through to injection into the public gas supply system.
The two TSM systems are to be used for the
first time in 2010.
TSM – an effective tool for technical self-regulation
In the context of incentive regulation, the DVGW technical safety
management system (TSM) is playing an increasingly important
role. In the gas sector, the TSM system already meets the quality
requirements connected with incentive regulation. The TSM system

Activities in Europe and throughout the world
The DVGW’s European and international standardization activities
within the relevant bodies CEN and ISO continued in 2009 without
any restrictions. The DVGW represents the German gas industry
on the European technical association MARCOGAZ. In the European water sector, the DVGW is active via EUREAU. One of the key
focuses of activities in 2009 was on the development of specific crisis,
risk and plant management standards for the water industry. Internationally, the DVGW has played an active role in the IGU (International Gas Union) and the IWA (International Water Association) for
many years.
DVGW office in Brussels
In a European Union with 27 or more members, European associations will have an increasingly important role to play. The European
Commission and the European Parliament are scarcely in a position
to process the large number of submissions concerning European
legislative proposals received from national associations. This is why
European institutions strongly encourage the development of opinions within European associations and it is becoming increasingly
necessary to play an active role in shaping opinions in these associations. The DVGW has clearly signalled its commitment to Europe
by establishing an office in Brussels. This office will ensure that the
association is more directly involved in information flow to and from
the EU Commission and can intensify existing contacts and develop
new contacts in a targeted way.
DVGW energie / wasser-praxis now includes regular reports on topics, proposals and trends from Brussels with a view to covering the
key issues, consequences, operations and adaptation strategies that
are important for the day-to-day work of DVGW members. The latest
information on all the key issues is also available on the European
1 2
platform in the members’ section of the
DVGW website.
Standards activities in Eastern Europe
The transfer of know-how and technical
standards to South-Eastern Europe continued successfully. A new challenge is cooperation with the Albanian Ministry of the
Economy and Energy under a letter of intent
concluded in December 2009. With financial
support from KfW and other institutions,
the DVGW codes of practice for gas systems are to be adapted to Albanian conditions on the basis of the example set by the
Coordination Committee for South-Eastern
Europe (Bosnia and Herzegovina, Croatia,
Serbia and Montenegro as well as the FYR of
Macedonia). Gas supplies in Albania are to
be expanded dramatically following a possible connection to the Turkey-Greece-Italy
pipelines).
Interchange with Serbia in the waster sector
was further intensified after the Serbian
Water Association had become a DVGW
member one year before. In 2009, the first
DVGW codes of practice for the water sector
were translated into Serbian and adapted to
local conditions.
The DVGW in the Far East
Following the establishment of good contacts with China in the water
sector and the introduction of the TSM system for water in cooperation with CUWA (Chinese Urban Water Association), contacts in the
gas sector were intensified in 2009. At the invitation of the Chinese
Gas Association (CGA), the DVGW was a co-organizer of the “First
Chinese-German Conference for the Safety of Urban Gas Supplies”.
On the occasion of the conference, the association presented the relevant code of practice for the inspection of gas pipeline systems.
In 2010, the DVGW will contribute to China Gas in Beijing. CUWA
and the Chinese Ministry of Construction also wish to intensify
cooperation.
Major conventions and conferences
In 2009, the annual gas and water industry conventions (gat and wat)
were held in combination with the Anniversary Conference. In the
case of the water sector, wat 2010 was even brought forward especially
because of the anniversary.
wat 2009 in Berlin
The 63rd wat was held on 31 March/1 April 2009 in combination with
the international WASSER BERLIN trade fair and once again provided a platform for key topics in the areas of technology, economics
and water quality. At wat 2009, the main emphases were on the new
Drinking Water Regulation, future tariff models, network and plant
maintenance strategies and the balance between energy efficiency and
hygiene. More than 950 managers and specialists from water supply
companies, industry, the authorities and higher education attended
the event. In addition to the specialist program, delegates also had
ample time for essential networking with their colleagues.
Anniversary Conference in Leipzig –
150 years of DVGW
The Anniversary Conference broke all attendance records. The association had invited
members to Leipzig under the motto of
“Moving Elements”. Almost 5,000 industry
representatives came to Leipzig to celebrate
the anniversary at the same time as obtaining information on the latest technical
developments as well as energy and water
policy targets. With a total of about 2,000
delegates attending, the 140th DVGW Members’ Assembly was the largest ever held in
the 150-year history of the association. At the
exhibition, some 280 companies presented
technical innovations for the gas and water
industry in a total exhibition area of 6,000
square metres. Once again, the combination of conference and exhibition was very
well received. The climax of the event was a
very special gala evening. The spirit of this
gigantic ‘”birthday party” was expressed
in a gala dinner for over 4,500 guests, an
extraordinary show programme and a lively
after-show party. Personal relations and the
feeling of togetherness among members were
reinforced, giving them strength to master
the challenges ahead of them. The feedback
received from delegates was extremely positive.

For 150 years, high technical, safety and quality standards adopted to protect consumers have
been based on DVGW codes of practice. The technical standards, developed in a clear and transparent process, represent a consensus on technical and organizational solutions for product,
services, systems and processes. The codes of practice are not an end in themselves but a key tool
for ensuring the safe and environmentally compatible use of technology in line with the requirements of legislative bodies, companies and consumers.

DVGW technical standardization work
Gas Supply SC
The quality of water supplies in Germany is exceptionally high. The
very low number of incidents connected with gas systems compared
with other countries also bears witness to the high standard of gas
supply systems and technical safety in Germany. The codes of practice
for the water and gas industries, which are continually being developed and improved by the DVGW technical committees, lay the foundations for these high levels of quality and safety. The work of these
committees is essential for technical interchange and for the drafting
and updating of codes of practice. In all, more than 200 technical
committees are involved. The specialist expertise and practical experience of a large number of independent experts are used to produce
documents that really set standards throughout the world.
“The future prospects for
gas supply are defined by the
conflicting requirements of
incentive regulation and the
changing energy market. As
a recognized standardization body, the DVGW must provide a reliable
technical framework and the tools required
for this development process.”
Chairperson of the Gas Supply SC
Dipl.-Ing. Andreas Hennig
The five gas and water steering committees (SC) are responsible for
controlling and monitoring the work of the technical committees by
agreement with the Board of Directors and the Executive Board. Each
of the technical committees (TC) deals with a specialist area and implements the program of work agreed with the responsible SC. Project
working parties (WP), which are formed on a temporary basis to deal
with specific issues, work on projects initiated by the higher-level
committees. DVGW employees coordinate the work of the committees and present the work of the association to national and international specialists.
Revision of the High-Pressure Gas Pipeline
Ordinance
The Ordinance Concerning High-Pressure
Gas Pipelines of 1974 was revised as a result
of changes in European legislation and related national regulations. Aspects calling for
special consideration were the reordering of
operational and plant safety, the implementation of the EU directives concerning services
in the Single Market and the recognition of
professional qualifications. Changes in the
system of experts as a result of amendments
to the Equipment Safety Act were also taken
into consideration.
The new Ordinance only applies to the construction and operation of high-pressure gas
pipelines which are used as energy plants for
gas supply as defined in the Energy Industry
Act.
A few key issues dealt with by the steering committees in 2009 are
presented below as examples of their work. Further information on
the latest DVGW codes of practice is available on the internet at www.
dvgw-regelwerk.de.

The gas “quality element”
Both within the industry and with the Federal Network Agency and
the energy regulatory authorities, the DVGW has initiated discussions with a view to developing an appropriate approach to quality
criteria for gas systems and the methods and tools needed for measuring compliance. Quality requirements generally combine minimum
standards and incentive elements. Technical safety and product quality must be regarded as minimum requirements in this context. These
requirements are laid down in general and specific legislation as well
as in generally accepted technical standards. Compliance is mandatory. The interim result of this discussion process is that compliance
with the minimum technical safety and product quality standards
will be an essential element of quality regulation for gas systems. In
addition, the DVGW is to place the body of data on incidents and
accidents on a broader footing; this will allow regulatory assessments
and decisions to be verified and critically reviewed and will provide
a representative, generally valid basis for comparisons in connection
with self-assessment.
G 2000 proves itself in practice
DVGW Code of Practice G 2000 “Minimum requirements for interoperability and connection to gas networks” has proved itself in
practice since it was issued in October 2006. Nevertheless, as a result
of rapidly changing conditions, it was necessary to carry out a major
revision of certain sections of the code of practice after only two
years. The revised version was then published in July 2009. The document is also available in English.
The revision became necessary as a result of changes in the legal
conditions and the further development of business processes in the
liberalized gas market. The section on biogas plants was revised to
reflect amendments to the Gas Network Access Ordinance, while the
section on technical network management was adapted to changed
business processes in the liberalized gas market and the data management section was updated in line with requirement for electronic data
interchange. The former Supplement 1, which
stated requirements for the determination of
line pack and was issued in September 2007,
now forms a new section in the main body of
the code of practice.
The amended Energy Industry Act of 29
August 2008 and the Metering Access Ordinance of 17 October 2008 state new requirements concerning metering point operation
and metering service. In this context, the
DVGW defined minimum technical requirements for gas metering in the new DVGW
Code of Practice G 687 and minimum technical requirements for the operation of gas
metering points in Code of Practice G 698.
The requirements concerning these matters
which previously formed part of Code of
Practice G 2000 have now been incorporated
in the new Codes of Practice and replaced by
a reference in G 2000.
Data interchange and code databases
As a result of the increasing refinement of
process segments on the basis of the cooperation agreement between gas network operators in Germany, the modelling and implementation of market processes on existing
computer systems is becoming increasingly
important. For the companies concerned,
this poses considerable challenges in terms of
equipment and human resources.
In 2008, the decision by the Federal Network
Agency concerning the “Basic Model for Bal1 7
ANNUA L
R E PORT
ancing Services and Rules for the German Gas Market” (GABi Gas),
established an entirely new network access regime for the German
gas industry. In view of the large number of IT systems which are
available on the market and used for energy data management and invoicing, the use of a secure, standardized electronic data interchange
procedure for business messages is even more important.
As a result of its extensive experience with gas transmission management, balancing group management and the transmission of data
on quantity deficits and surpluses, the DVGW is playing a key role
in the national and international standardization of automated data
interchange.
DVGW Service & Consult also operates a public database for the
identification of market partners on the basis of standard codes,
which is a prerequisite for electronic data interchange. Quality-assured access to the database is ensured on an impartial, non-discriminatory and open basis.
The autonomous role of the DVGW in developing message types for
use purely in the gas sector has been recognized by the authorities
and message types are developed on the basis of European standards
in cooperation with all the players in the gas market, including the
software industry.

Support for the national implementation of
the Energy Services Directive
Network and metering point operators face
a large number of new tasks with very tight
deadlines as a result of the liberalization of
metering. This applies especially to the new
provisions of Section 21b (3a) and (3b) of the
Energy Industry Act. Since 1 January 2010,
the installation of new metering equipment
providing the connection user with information on actual energy consumption and
duration of use has been required.
These requirements apply to buildings newly
connected to the energy supply system or
undergoing major refurbishment. Section
21b (3b) of the Energy Industry Act also calls
for the replacement of existing metering
equipment.
On the basis of the action recommended
by the associations, the DVGW, acting as a
technical and scientific standardization body
for the gas and water industries, published
a specification for “Gas Meters in Accordance with the Energy Services Directive”
which indicates how metering systems can be
adapted to the requirements of Section 21b
(3a) and (3b) of the Energy Industry Act of 1
January 2010 with minimum effort.
Gas Applications SC
“One of the main reasons why natural gas is so
well-positioned is that it comprehensively fulfils the
requirements of the integrated energy and climate programme in combination with advanced, highly efficient
technologies such as CHP plants for residential use.
Natural gas will continue to have considerable market
potential in the future as the new advantages of higher efficiency and
improved climate protection through new technologies will be combined with the existing benefits of convenience and good economics.
Together with manufacturers, we will need to define acceptable cost
levels and to develop appliances meeting these requirements.”
Chairperson of the Gas Applications SC
Dr.-Ing. Bernhard Klocke
A holistic approach to biogas
The market for biogas plants is set to grow dramatically as a result of
the amendment of the Renewable Energies Act (EEG). The treatment
of biogas to obtain gas of natural gas quality is especially promising.
If biogas is fed to the natural gas system, it can be converted into bioheat, bio-power or biofuel at practically any location. From the beginning of biogas activities, the DVGW has considered the entire process
chain from biogas production through to injection. Discussions have
focussed on the potential for biogas, sustainable biomass production
and aspects of gas treatment and conditioning.
In Germany, DVGW, DWA, the occupational health and safety bodies
and Fachverband Biogas are working together to avoid duplication
of effort and the development of competing standards for biogas
systems. A working party of the biogas project committee has started
work on a provisional inspection specification (VP 265-2) for the
operation and maintenance of thermal biogas production plants. In
addition, the DVGW will issue codes of practice for the construction
of gas production plants (fermenters).
Reducing the sulphur content of natural gas
Natural gas faces competition from other energy sources not only
as a motor fuel but also on the heat energy market. In the wake of
discussions on reducing the sulphur content of natural gas to 10 mg/
kg in line with the 10th Federal Pollution Control Ordinance and
DIN 51624, it has become necessary to revise Code of Practice G 260.
The objective of the draft is to ensure that natural gas is perceived as
an environmentally compatible source of energy in comparison with
other fossil fuels and to ensure its future.
Other points under discussion in connection with the revision of
G 260 are as follows:
• It may be necessary to condition natural gas as the current
harmonization proposal of EASEE-Gas for gas transmission
systems and connected underground storage facilities deviates
from the present value for dry gas distribution systems.
• It has been proposed that the moisture content, hydrocarbon content and hydrocarbon dew point should be indicated in figures in order to make the presentation easier to understand for the
general public. As new players enter the gas
market, the Code of Practice will be used
not only by gas industry specialists.
• Finally, in line with normal practice in other European countries, the energy value is to be indicated by the methane number first in MJ and then in kWh.
Support for sulphur-free and low-sulphur
odorants
As natural gas is odourless and would otherwise not be noticed in the case of a leak,
odorants are added to natural gas supplied
to distribution systems. Various activities
have been initiated with a view to reducing
the sulphur content of odorants, including
the use of sulphur-free or low-sulphur odorants, the keeping of odour statistics and the
replacement of the present odour cards by
odour tubes which reflect the actual odours
of odorants more precisely. A timetable for
the transition to sulphur-free or low-sulphur
odorants gives companies wishing to make
the changeover an indication of a cost-effective, efficient approach.
Natural gas as a motor fuel
In view of the growing number of natural gas
refuelling stations in Germany, natural gas
is now regarded as a normal motor fuel and
is therefore subject to the requirements of
the 10th Ordinance issued under the Federal
Pollution Control Act (10. BImSchV). An
administrative regulation issued under the
Ordinance calls for standardized, comprehensible, transparent procedures for fuel
sampling at refuelling stations and practicable analytical procedures for determining the
key parameters of fuels. Code of Practice G
264 contains instructions for representative
sampling at natural gas refuelling stations so
that the composition of natural gas used as a
motor fuel can be officially monitored.
The Code of Practice also states requirements
for the determination of the methane or
octane number, one of the basic parameters
that define the minimum requirements for
natural gas as a motor fuel.
DVGW Code of Practice G 651, “Natural Gas
Refuelling Stations”, which is identical to
VdTÜV Code of Practice M 510, was revised
1 9
ANNUA L
R E PORT
D V GW
in cooperation with TÜV and published in
July 2009. This Code of Practice is a compendium of codes and standards reflecting the
state of the art and also applies to refuelling
stations dispensing treated biogas.
Micro-CHP plants
Natural gas-fired plants for the combined
generation of heat and power (CHP) help
reduce CO2 emissions and therefore make
a contribution to climate protection. The
decisive advantage of the combined generation of heat and power as opposed to separate
generation is the high overall efficiency of the
process, allowing a primary energy saving in
excess of 10 %.
A number of national (DIN, DKE/DVGW
and VDI), European (CEN/CENELECC,
CGEJN) and international (IEC) institutions
have focused on standardization for microCHP plants. In order to coordinate these
activities, a joint proposal for a uniform approach has been adopted at all levels and by
all bodies of the DVGW.
Water Industry/Water Quality/
Waterworks SC
“The multi-barrier approach is one of the fundamental
principles of water supply in Germany. In other words,

Anthropogenic trace substances in the water cycle
The intensive use of anthropogenic materials including drugs, additives in foodstuffs and industrial products, cosmetics and pesticides
has a detrimental impact on bodies of water including those used as
drinking water resources. Adopting a proactive approach, it is necessary to reduce these impacts to a minimum so that we can continue
to produce drinking water by relatively natural treatment processes
in the future. A joint position paper issued by DVGW, DWA, and
Wasserchemische Gesellschaft in May 2009 highlights the potential
hazards, identifies loopholes in national and European legislation and
proposes possible approaches to be used by all the parties involved
with a view to minimizing pollution at the source.
Amended EU Biocides Directive
Currently, about 50,000 biocides are registered throughout the European Union, including about 18,000 in Germany. These substances
range from antibacterial detergents to wood protection agents,
anti-fouling paints to insecticide sprays and drinking water disinfectants. The DVGW prepared a comprehensive statement covering the
requirements for water protection and water treatment. The DVGW
will also focus on links to the EU Drinking Water Directive and the
2 0

future Building Products Regulation and propose post-registration
monitoring in bodies of water to assess the environmental compatibility of biocides and their metabolites.
Spreading of compost in water protection areas
The DVGW and Bundesgemeinschaft Kompost (BGK) have agreed on
a joint statement concerning the spreading of compost on agricultural
land from the point of view of water resource protection. In connection with water protection, the use of compost may pose certain
hazards. Especially where compost is spread on land in water resource
conservation and drinking water protection areas, appropriate consideration must be given to the special protection needs of these areas.
BGK will include in its test certificates indications of the suitability of
compost for use in water resource protection areas.
Geothermal energy and water protection
The use of renewable geothermal energy has been increasing dramatically for several years. The risk of adverse impact on groundwater
must be avoided in connection with geothermal energy. The DVGW
has drawn up principles for the design, construction and operation
of geothermal probes which were stated in greater detail in 2009 as
a result of new technical developments and specialist discussions.
These principles include a general obligation to report such projects
to the authorities and obtain approval, the priority of drinking water
resource protection over geothermal energy use, a ban on geothermal
energy use in water resource conservation areas and the requirement for all systems to be built by specialist contractors with W 120
certificates.
Safety in drinking water supply
Over the past few years, national, European and international discussions and activities have increasingly focussed on the issue of safety.
Examples include new concepts such as the World Health Organization (WHO) Water Safety Plan (WSP) as well as CEN and ISO
standardization efforts. The DVGW has developed an overall safety
concept for the water sector including Codes of Practice W 1001 (Risk
Management in Normal Operation) and W 1002 (Organization and
Management in Crises) as well as recommendations on organization and management in water supply (DVGW Code of Practice W
1000:2005). A portal with further information and frequently asked
questions (FAQ), which is regularly updated on the basis of practical
experience, has been established on the DVGW website. An in-house
training scheme to reinforce methodological competence among
water company personnel is currently being developed.
“In order to maintain the
proven high quality of German
water supplies, we need to
exert an influence internationally. The DVGW has taken up
the challenge and is playing
an active, instrumental role in European and
international standardization. The objective
must be to bring the experience embodied
in the DVGW codes of practice to bear within
ISO and CEN and to present these documents
as a successful and reliable basis for standardization.”

Revision of network and damage statistic
Water companies need reliable statistics to
predict failure and damage rates and assess
the remaining service lives of their systems.
The objective of the new draft for DVGW
Code of Practice W 402 is to establish a
consistent body of system, condition and
environmental data for water distribution
systems. These data will be used mainly as
a basis for maintenance, especially for the
rehabilitation of supply systems. In addition,
the data may be used for statistical evaluations for various operational and entrepreneurial purposes.
Decision-making aids for the rehabilitation
of water systems
In view of the continuously growing pressure on costs, many water companies face the
question of how to realize savings on their
pipeline systems at the same time as maintaining the high quality of their service and
the fabric of their systems. The new DVGW
Code of Practice W 403 provides practical
aids for decisions on the rehabilitation of water distribution systems based on data compiled in accordance with Code of Practice
W 402 mentioned above. Various rehabilitation methods are presented. The conclusion
drawn is that efficient, cost-effective action
in individual cases calls for well-founded,
detailed knowledge of a company’s system.

Specification of supply quality in water distribution
Supply and service quality is a key decision-making factor for
consumers and is also becoming an increasingly important issue in
water distribution throughout Europe. Thanks to the DVGW codes of
practice, Germany has reached a very high standard compared with
other European countries in terms of drinking water hygiene, uninterrupted supply and constant pressure in distribution systems as well
as the use of materials fit for service with drinking water. The DVGW
has established a new project committee to specify aspects of service
quality in water distribution.
BALSibau initiative
Secure utility supplies at all times are becoming increasingly important for society. Gas, water, electricity, district heat, wastewater and
communication networks are complex and are often installed in very
limited space, crossing each other repeatedly. Although considerable
attention is paid to accurate system plans, construction work near
to existing lines results in damage almost every day. The total cost is
estimated at about 200 million euros per year.
BALSibau (federal working party of pipeline and cable operators
for the minimization of construction damage) is a joint initiative of
the DVGW and Deutsche Telekom. It is hoped that the electricity
industry will join the initiative at a later date. One of the key tasks of
BALSibau is to provide project owners and contractors with information on the causes and consequences of damage. In 2009, a national
certificate (“excavator driver’s licence”) was introduced for employees
with training in accordance with DVGW Code of Practice GW 129
(“Safe Construction Work Near Utility Lines”). During the 2009
construction season, training was provided for some 3,000 excavator
operators.

“The quality of drinking water
must be secured beyond the
point where it leaves the
distribution system and enters
the consumer’s domestic
installation. Clearer statutory provisions will focus public attention on
domestic installations as they will be mandatory for building owners. The DVGW Codes of
Practice and products certified on the basis
of these documents warrant compliance
with these requirements. To ensure that this
remains the case in the long term, the DVGW
carries out research in the area of water use,
reinforcing the foundations for its Codes of
Practice.”
Chairperson of the Water Use SC
Dipl.-Ing. Wolfram Wollgam
Quality assurance at the water tap
Domestic drinking water piping is characterized by special operating conditions including exposure to hot and cold water, intermittent operation, high ambient temperatures,
the use of a wide variety of materials and unfavourable surface/volume ratios. Nowadays,
drinking water installations supplying water
to the public are already monitored by the
public health authorities. In future, the statutory provisions concerning private drinking
water systems will also become clearer and
more precise. The point where quality will be
assessed is the water tap.
As a technical standardization body, the
DVGW plays its part in ensuring compliance
with quality requirements at the water tap
by issuing and updating codes of practice for
drinking water installations. To a large extent, the process of European standardization
has already been completed for many components, parts, equipment items and valves.
This means that the first step towards the
free movement of goods within the EU has
already been taken even though additional
European requirements still need to be established with regard to the fitness for purpose
of materials and a European solution which
had almost been adopted could not be implemented. In this context, the DVGW codes
of practice ensure that the special features
of materials and construction conditions are
taken into account. The codes of practice also
form the basis for the national certification of
products.
Materials in the spotlight
Drinking water installations are not just a
means of transporting water. They are, as
it were, the packaging of a material that is
essential for life. The material of pipes, valves
and fittings is in continuous contact with
drinking water. The internal corrosion section of DVGW has made a key contribution
to maintaining the quality of drinking water
by supporting a large number of research
programmes, processing and revising codes
of practice and issuing technical publications.
Optimizing microbiological conditions
Not only the chemical properties of drinking water may be impaired.
Unfavourable conditions can promote the growth of micro-organisms, especially if unsuitable materials are used or ambient temperatures are unfavourable. This is why DVGW committees are working
on codes of practice to optimize microbiological conditions with a
view to maintaining drinking water quality. Quality problems are
mainly registered if water installations are in poor condition. Work
is also in process on requirements for the rehabilitation of drinking
water installations.
TRWI compendium
To date, DIN 1988 “Codes of Practice for Drinking Water Installations” and the related product standards and DVGW codes of
practice have represented the most comprehensive, balanced body of
standards in Europe. In Europe, work is now in progress on European standard EN 806. a European version of DIN 1988 which will
eventually be a five-part basic or functional standard. In this first
stage of European standardization, it will not be possible to include
the required degree of detail in all areas, as it is necessary to take into
consideration European diversity. As we will need to cover national
specialities and considerations in additional or supplementary standards, DVGW and DIN have together taken on the task of compiling
European Standard EN 806 and national supplements in a noncontradictory work, the TRWI compendium. This compendium is
intended for a wide range of target groups, including building owners,
water companies, plumbers, engineers, wholesalers and manufacturers as well as authorities, institutes and other bodies.

Successful networking
In 2009, major projects were brought to a successful conclusion as a result of cooperation between the DVGW and
its own and external research institutes. The main focus
was on the assessment of a variety of gas application
technologies in the context of the new statutory climate
protection provisions. In addition, approaches for the
optimized maintenance of networks were developed in
connection with incentive regulation and unbundling in
the gas sector. On the water site, research projects covered
areas ranging from production to distribution and treatment.
Links between DVGW research activities and European
partners were expanded. In addition to its membership
of GERG, the European Gas Research Group, DVGW is
now more closely connected to European networks in the
water sector. A major step in this direction is DVGW‘s
membership of WSSTP, the European Water Supply and
Sanitation Technology Platform. Via WSSTP, DVGW is
now in a position to make strategic contributions to EU
framework research programmes.
DVGW is also intensifying international research cooperation with a view to benefiting from synergy effects. The
association has stepped up its activities within the IGU
(International Gas Union). At the World Gas Conference
in 2009, DVGW presented one of the key projects for
2009, the Prognos study on the role of gas in applications
technology.
Prognos study: “Gas Plus” technology for the future
In order to allow well-founded predictions concerning
the future development of the natural gas market, the
study investigated and assessed 24 different technologies,
concentrating on legal conditions, technical availability,
construction aspects and economic viability. The systems
covered included various oil- and gas-fired condensing
boilers, CHP units, pellet heating systems and district
heating systems for larger and smaller areas. The main
conclusion was that gas is an attractive option in most applications in combination with advanced technology. This
applies especially to condensing boiler systems with solar
support for drinking water heating. This is not only the
right technology for the new climate and environmental
policy regime of the German government’s integrated
energy and climate programme. It is also the most economical solution. A decisive factor in maintaining and
expanding the position of natural gas in future will be
that this fuel meets all of the requirements of the integrated energy and climate programme in combination
with high-efficiency advanced technologies. The future of
natural gas therefore lies in “Gas Plus” technology.
Gas technology innovation campaign
In its study “Innovative Technologies for the Use of
Natural Gas as a Fuel”, the prognos institute highlighted
the prospects for natural gas as a fuel in the context of the
new climate policy requirements.
On the basis of the study, a plan for a gas technology
innovation campaign was developed. In contrast to the
scope of the prognos study, which concentrated on gas
applications, this campaign will cover all areas of gas
technology, especially networks. Other aspects are connected with the diversification of gas procurement.
2 6
The main focus of research work under the initiative is
the result of the conclusion that gas must increasingly be
seen as one component in an overall energy system. It is
intended that the results of the work will contribute to
the development of innovative technologies for ensuring
the supply of gas through pipeline systems in the medium
to long term, which will be implemented in cooperation
with gas companies and industrial partners in the context
of more stringent environmental and climate protection
requirements. The individual projects form five thematic
clusters.
Systems analysis: Projects forming part of this cluster
will assess the role of gaseous fuels supplied via pipeline
systems in future energy supplies in the new business
environment, especially with respect to climate protection and regulation. The objective is to identify the future
role of natural gas as a fuel in the new energy and climate
policy context with respect to energy efficiency and the
integration of renewable energy sources.
Gas production and treatment: The objective of this
thematic cluster is to develop technology for the further
expansion of biogas use. The main focuses are on increasing the efficiency of biogas production and treatment,
new ways of producing biogas, especially thermal processes, and injection into gas pipeline systems.
Network management: This cluster includes research
on topics related to networks and operation. The main
focus is on network planning and the optimized use of
assets. Key aspects include the design of smart grids, the
creation of injection structures for gases from renewable
sources and the development of new processes in connection with regulation as well as demographic effects.
Application technologies: The objective of this cluster is
to promote new gas application technologies in line with
the results of the prognos study, based on the “Gas Plus”
approach. The main focus is on practical research and development work to be carried out in the near future in cooperation with industry with a view to increasing energy
efficiency and boosting the role of renewable components
in applications technologies. The combined generation of
heat and power using a number of different cogeneration
technologies is one of the main areas covered.
Cooperation and communication: This cluster is of
crucial importance for linking the DVGW innovation
campaign with other organizations in the gas industry.
The external communication structures required will be
coordinated within this cluster.
SNG: the use of biomass as a fuel
The production of SNG (substitute natural gas) from
dry biomass rich in lignin is an attractive option for the
generation of gaseous fuels. Whereas the production of
methane by fermentation and subsequent injection into
the natural gas systems are already established technologies in Germany, the production of SNG from biomass
by thermochemical processes is still at the R&D stage.
In a project undertaken with the financial support of the
Baden-Württemberg state foundation, scientists at the
DVGW research unit of the Engler-Bunte institute in
Karlsruhe are currently investigating the use of honeycomb catalysts for the methanation of synthesis gas. Pilot
projects to demonstrate technical feasibility and gain initial operating experience will be essential for the further
development of this approach.

Computer-aided maintenance of gas supply systems
Efficient, consumer-oriented network management calls
for intact, well-maintained pipeline systems. The cost
of maintenance and any repairs which may be required

is possible. In this context, electronic prediction and
assessment systems can provide objective evaluations
and assistance with the decision-making process. This

Technology Centre, a model for determining optimized
flushing intervals was developed. The objective was to
sustainably avoid complaints about brown water, and to
use the resources available for network maintenance as
efficiently as possible.
Sustained reduction in network expenses through optimization and risk analysis
Local distribution system operators are making considerable efforts to reduce costs and to adapt their network
structures to changing political, technical and demographic conditions. Computer-aided processes such as
target network planning help them to develop optimized
structures for gas and water distribution systems and
to adapt them to present and future supply situations at
minimum cost. In the near future, a research project initiated by the DVGW is to develop tools for the planning
of rehabilitation work on the basis of cost and risk criteria
in order to allow cost-effective network modifications.

processes. In order to assess energy consumption, it was
therefore necessary to develop a calculation procedure for
the allocation of electricity consumption. The proposal
made by the research institute means that this is now
possible and further potential for energy savings can be
accessed.
Compilation of information on water softening plants
Nanofiltration and low-pressure reverse osmosis processes are being used increasingly frequently at central
water softening plants. There are considerable differences
between individual plants, not only in terms of mode of
operation and separation properties but also as regards
the objectives of treatment, which depend on the composition of the raw water. In order to obtain an overview
of these plants, information on the plants currently in
operation in Germany was compiled. The results indicate
that the processes mentioned are reliable, practicable and
economically competitive. However, this only applies if
the concentrate disposal method used is environmentally
compatible and economically viable. Various solutions
may be suitable and are currently being investigated by
practically oriented R&D projects.

Gas and water products
National certification procedures continued largely in
accordance with plan, while European procedures were
significantly below the planned levels. Many companies
are holding their innovations in the gas sector back until
the impending European eco-design legislation has been
finalized and the consequences are clear. DVGW CERT
GmbH is actively contributing to this development via the
Marcogaz Standing Committee Utilization. Possibilities of
providing certification support for the new energy-efficient
technologies and appliances now coming onto the market
are being investigated. An “Eco-Plus” label including key
requirements of the European eco-design directive is
being developed to give manufacturers an opportunity to
mark their especially energy-efficient appliances. A draft
certification programme for this purpose is being drafted
in cooperation with the gas applications section and the
inspection bodies. With a view to extending the range
of services for the gas sector, accreditation for the GS
(equipment safety) mark for solid fuel firing systems has
been applied for; a further application has been made to
extend the scope of accreditation under the EC Construction Products Directive. These certification procedures
are targeted mainly at the German market, which remains
economically stable.
In cooperation with gas inspection bodies, DVGW CERT
is working on procedures to demonstrate the fitness of
gas appliances for operation with biogas with a view to
allowing appropriate certification. Some manufacturers
have already indicated that they are interested in special
confirmation of fitness for the purpose.
The liberalization of metering activities as a result of European legislation also offers prospects for certification procedures. Over the next few years, smart metering, initially
promoted by the electricity industry, will also become very
important for gas and water invoicing systems. New certification and inspection procedures are being developed in
cooperation with meter and component manufacturers.
DVGW CERT is responsible for work package 2 “Current
Certification Practice” of the GASQUAL project launched
at the beginning of 2009.This is a broad-based European
study on the effects of gas quality changes on safe appliance operation. Within the project, a comprehensive
survey of all European manufacturers and certification
and inspection bodies was conducted. The EBI inspection
agency is playing a key role in work package 5, “Equipment
Tests”. As all the European manufacturers’ associations
including EHI as well as major customers in the gas sector
are participating directly in the project, DVGW CERT and
EBI will be able to put their competence to the test and to
incorporate the conclusions of the project in future inspection and certification procedures in the near future.
As regards water products, economic development in 2009
exceeded the planned figures. The reason was the large
number of new inspection standards which were applied,
As the expected CE mark for plastic pipes is not likely to
be implemented in the near future, there is some interest
in national certification for new pipe materials, No inspection standards are currently available for such certification.
Specialist contractors
In September 2009, DVGW CERT GmbH was accredited
by the DATech unit of TGA GmbH (a member of the German Accreditation Council) as the world’s first certification body for the certification of gas, water and district
heating system construction and maintenance specialists.
This means that the company can now offer its customers
the same quality standards recognized throughout Europe
for the certification of specialist contractors (pipeline and
plant construction, well drilling, etc.) as in the areas of
product and management system certification where it has
been active for many years.
Accreditation has become even more important as a result
of the adoption of a German Accreditation Act and the
establishment of a central German accreditation body as
of 1 January 2010. This act is intended to ensure comparable quality standards for accreditation throughout Europe.
Certificates issued by accredited bodies will be regarded as
equivalent and will enjoy mutual reconfiguration within
the Single European Market.
In response to requests received from many pipeline
construction contractors, a joint application procedure for
specialist contractor and QM certification was introduced.
This may also be combined with the prequalification
procedure.
Although demand for geothermal wells continues to soar,
only very few of the drilling contractors active in this area
are certified in accordance with DVGW Code of Practice W 120. As a result, many of the wells fail to provide

Management systems
As regards certification in accordance with ISO 9001, ISO 14001 and BS
OHSAS 18001, there is still a clear trend towards integrated management systems. Many companies wish to benefit from the synergy effects of combining
several systems (quality, health and safety and environmental management
systems). In addition, management system certification can be combined
with other specialist DVGW certifications (e.g. to Codes of Practice GW 301
or W 120) or Technical Safety Management (TSM) certificates.
Accreditation for environmental management system certification in accordance with ISO 14001 has been successfully extended to product manufacturers, which can now apply for combined certification to ISO 9001 and ISO
14001.
DVGW CERT GmbH is the only German partner in a European project

programme to the changed requirements of the industry and continued further development of its modular training system. The DVGW
training programme takes account of all relevant developments and
innovations in technology and standards and ensures that the latest
changes are covered competently in its courses.
TRGI training scheme once again a resounding success in 2009
DVGW Code of Practice G 600 “Code of Practice for Gas Installations”
is the most important standard for gas installations and an outstanding
link between system operation and installation contractors. In 2008,
DVGW and ZVSHK, the central association of the German plumbing,
heating and air conditioning trade, agreed on a joint campaign for the
introduction of the code of practice including a standardized national
training programme. Following two very successful years, the training
programme was completed in December 2009.
In 2009, more than 180 courses were held at over 100 locations to
familiarize about 6,000 participants with the new Code of Practice.
DVGW and ZVSHK guaranteed the quality of the courses and ensured
that they were provided to a high standard throughout the country in
cooperation with network operators and trade associations.
Training for industrial gas customers
Safety is also the top priority in the operation and maintenance of industrial natural
gas systems and equipment such as heaters
and generators. Under the Energy Industry
Act, energy systems of this type must be
constructed, operated and maintained in accordance with the “generally accepted rules of
technology”. This requirement is considered
to have been met if DVGW codes of practice
are applied.
With a view to supporting the large number
of commercial and industrial gas customers
in the performance of their organizational
duties, DVGW has developed special training
modules, which it offers at regional centres,
for the technical personnel of industrial
gas customers and for employees of service

Germany. The objective of these events, which
will continue in the future, was to discuss
relevant innovations and background information, case studies and ideas from other
companies with the participants, to provide
3 8
them with up-to-date information and to allow an exchange of experience. During the
2009 forums, the topical issues covered included incentive regulation, the consequences of failure to comply with codes of practice, the repair and maintenance of gas and
water installations and reports by experts on their experience. The forums were very
well received by the 250 participants.
Current lead professions in the power, gas and water sectors
The restructuring of vocations and courses of study in the energy and water sectors
has led to generally recognized standards for vocational qualifications. Qualification
standards for operations personnel at all qualification levels from skilled worker to
master craftsman and engineer have been formulated. Training experts from utilities
and associations have actively contributed to innovations in the structure of training in
line with the new possibilities offered by the Bologna process and the new Vocational
Training Act.
The lead professions are defined in the four basic standards DIN-VDE 1000-10, S 1000,
G 1000 and W 1000. These lay down requirements for persons working in the fields of
electrical engineering, energy supply systems, gas systems and drinking water supply
systems. The DVGW codes of practice also include company organization requirements.
Prof. Lendt from the Ostfalia University of Applied Sciences developed the master‘s
degree course for gas, water and power network engineers on behalf of DVGW and the
industries concerned. In the development process, Prof. Lendt received support from
Esslingen and Trier Universities of Applied Sciences. The curriculum is based closely
on the tasks and activities of technical managers, as stated in the relevant standards.
The master‘s degree course, which is currently in the final stages of accreditation, will
probably be offered for the first time in 2010.

DVGW Academy increasingly popular
In 2009, the DVGW Academy was very successful, with
220 seminars and about 2,500 participants. The Academy
systematically develops skills in the areas of organization/
law, business administration, employee management, customer orientation and secretarial/assistance services.
The DVGW Academy continually optimizes its range of
services and develops new courses in line with demand.
All the courses offered are specially tailored to meet the
requirements of the gas and water sectors and are increasingly provided in-house for customers. In 2009, the area
with the highest demand was customer orientation, followed by employee management and business administration.
The trend towards individually tailored training courses
continued in 2009. Apart from individual training, the
emphasis is increasingly on concepts for systematic employee development.
“Personnel development” was added to the Academy‘s
fields of activities in 2008/9. The changes in the energy and
water sectors over the past few years have meant that personnel development is likely to become a key element in
ensuring the competitiveness of companies in the future.
With the long-term experience of the Academy trainers in
the gas and water sectors and the many successful training
systems implemented by DVGW over the past few years,
the Academy is in a position to provide comprehensive
consultancy services from analysis through to conceptual
design and implementation.

Central and regional – the DVGW offering
Apart from centrally organized courses, the many events
organized at the regional and local level play a key role in
the DVGW information and training system. The local
groups mainly offer brief information events on topical
themes which are dealt with in more detail by the professional training events available. The regional groups concentrate on specialist information with a regional focus.
All in all, more than 12,000 participants attended events
organized at the regional or local level in 2009.
The right training with QUA.SI
QUA.SI is a free-of-charge Internet-based service offered
by the DVGW to ensure that employees of gas and water
companies receive precisely the training they need for the
performance of their present and future work.
QUA.SI assists the manager responsible to plan, manage
and document the training required for technical personnel.
Media for members and other specialists
In processing and providing up-to-date specialist information, the classical print media and electronic media
supplement each other.
DVGW internet presentation expanded
Up-to-date specialist information, broken down by topics
and services for specialist visitors and members, is available via the comprehensive DVGW information portal.
The main emphasis is on DVGW activities and services, which are continually expanded. A special website
concentrating on the anniversary conference and the 150year history of the DVGW was also established.
Anniversary festschrift in considerable demand
All the delegates to the anniversary conference received
a coupon which they could exchange for their copy of the
anniversary festschrift fresh from the press. The 400-page
publication, entitled Elemente, die bewegen. Mensch und
Technik im Gas- und Wasserfach (“Moving elements –
people and technology in the gas and water sector”) was
very well-received.
members. Thanks to the support received from a large
number of sponsors, members received an extraordinary
festschrift which will continue to be of value for many
years.
DVGW energie|wasser-praxis – a high-profile specialist
journal
“DVGW energie|wasser-praxis”, published by DVGW via
its affiliate wvgv as a specialist journal and the association magazine, is now the leading specialist journal in the
sector, with a circulation of about 13,500 copies. The journal reports on all the key developments in the industry
and the association. Key articles are also published in
advance in the members’ section of the DVGW website.
The prestigious book combines a review of the history of
the gas and water industries with highly artistic photographic documentation. The 200-page historic review
presents an exciting view of the development of gas and
water, with many illustrations and quotations. The additional 200-page photo section includes high-quality monochrome photographs of people at their everyday work,
ensuring secure supplies of gas and water in Germany.
The book gives an impression of the tremendous achievement of the gas and water sectors, the value of the
association‘s work and the identity and cohesion of its

The association
Introduction
For 150 years, the DVGW has been setting safety and
quality standards for the gas and water industries. The
association is committed to the successful technical
self-regulation of the gas and water sectors. German laws
define general protection and safety objectives, while
more detailed requirements are developed by the experts
of the DVGW.
Members can directly influence developments
in their industry via the General Meeting, the
various bodies of the association and active
participation in the specialist committees of the
DVGW. The networked, decentralized structure
of the DVGW ensures a rapid, comprehensive
flow of specialist information.
The Central Office, the regional and local offices, certification and testing bodies, research and training institutes
and specialist committees of the DVGW all work together
closely and maintain intensive dialogue within the industry. Close contacts with ministries, authorities and other
associations are also essential as a basis for decisions on
the future-oriented further development of the German
and European gas and water industries.

The DVGW has nine regional offices distributed throughout Germany. The tasks of these offices are in line with
the fields of activity of the DVGW, but also include
topical regional issues. In organizing events, support
for members and certification work, nearness to the
members ensures that individual contacts are available
and support is provided as and when it is required at the
same time as generating new impetus for the association‘s
work. The activities of the regional offices are rounded off
by regular contacts with the ministries and authorities
of Germany‘s federal states, including discussions with
parliamentary representatives. One of the main focuses is
on cooperation on the DVGW Technical Safety Management (TSM) system.

Local Offices
The 63 DVGW/DELIWA local offices provide the infrastructure required for information transfer ranging from
regional contacts to work on codes of practice. As a multiplier for the DVGW, the local offices pass on specialist
knowledge and foster a mutual interchange of information. This means that all the individual members find out
rapidly and reliably about what is happening in the industry. This local strategy is the key to success in information
distribution. Outstanding regional contacts and considerable voluntary commitment lay a firm foundation for the
attractive range of activities offered by the local offices.
The main focuses of work with members include information events, specialist training, excursions and local
exchanges of experience. The 300 events organized by the
local offices each year mean that the individual members
keep abreast of the latest developments in their industry.
The DVGW/DELIWA local offices are assigned to the
regional offices for organizational purposes. Their work is
coordinated by six regional coordination groups:
