INTRODUCTION
1.1. Background
The project ‘Reduction of non-revenue water in
SE Europe’ is implemented by Aquasan network
B&H and GIZ, through Open regional fund for
modernization of municipal services, financed by
German Federal Ministry for Economic Cooperation (BMZ) and Swiss Agency for Development
and Cooperation (SDC). The project covers three
countries in SE Europe: Macedonia, Kosovo and
Bosnia and Herzegovina.
Project activity area is focused on: (1) increasing awareness and capacities relating to relevant
decision-makers, managerial and technical part,
through a number of theoretical and practical (onthe-job) trainings; (2) designing, adaptation and
sharing tools and methods for reduction of nonrevenue water, including the best cases derived
from practice; (3) implementation of concrete
measures for reduction of non-revenue water, detailed analysis of non-revenue water, improvement
of information flow, organization of tasks, procurement and installation (application) of NRW
equipment; (4) creating a large number of trained
experts for NRW.
The project started in November 2014, with
creation of application form and applications of
interested water supply companies through national associations of waterworks and communal
companies in participating states.
A total of 14 water companies applied in Bosnia and Herzegovina, and three partner companies
were selected:
PUC
Vodovod i kanalizacija a.d. - East New
Sarajevo;
PUC
6. mart d.o.o. - Gorazde;
PUC
Vodovod i kanalizacija d.o.o. - Velika
Kladusa;
For the purpose of selecting one pilot company
in each country, there was a separate questionnaire
made. The questionnaire was additionally adjusted
by consulting company SETEC and regional experts Sead Badnjevic and Bojan Ristovski, and
then it was submitted to partner companies. After receiving filled questionnaires and performed
analysis for B&H, the PUC Vodovod i kanalizacija
Ltd. company of Velika Kladusa was selected as
the pilot company from Bosnia and Herzegovina.
Within the project, there were two trainings
held for partner companies from all three countries, in Skopje, Macedonia (17-19 June 2015) and
Klagenfurt, Austria (3 – 6 August 2015), dedicated
to technical staff as a part of working package that
encloses strengthening the capacities of water supply companies. There was also a one-day training
held in Klagenfurt, Austria (6-7 August 2015)
dedicated to the decision-makers in partner water
companies and municipalities.
Besides this project, PUC Vodovod i kanalizacija Ltd. Velika Kladusa is active in other regional projects. Within the implementation of
Danube Water Program, the company participated
in setting the benchmarks of company’s activity
according to IBNET methodology. PUC Vodovod
i kanalizacija Ltd. Velika Kladusa, as part of GIZ
(ORF MMS), will receive business tools for planning in the field of property management, which
will be tested and installed in seven pilot communal companies from countries included in the
project. A detailed training in all aspects of using
this tool will be given to administrators, users and
management.
1.2. The Project area and utility
factsheet
Velika Kladusa is a town and a center of municipality at the far north-west of Bosnia and Herzegovina. On the south it borders with municipalities of Una-Sana Canton, Buzim and Cazin, while
from west, north and east it borders with Croatia,
i.e. municipalities of Cetingrad, Vojnic, Topusko,
Glina and Dvor. There were 52,908 inhabitants in
Velika Kladusa in 1991, while the municipal surface
is 331.55 km2, which makes Velika Kladusa one of
the most densely populated areas in B&H. It is estimated that there are about 40,000 inhabitants in the
municipality nowadays. The municipal territory
was administratively divided into 14 local communities. The geo-traffic position of Velika Kladusa
is very significant for its population, for Una-Sana
Canton and for Bosnia and Herzegovina as a whole.
The land in Velika Kladusa municipality presents
one of the most important factors in the municipal
development, considering geographic position, climate and hydrological circumstances, geologic and
petrologic characteristics. In the total land surface
area, the highest percentage goes to the farming
land – 22,375 hectares or 67.48% of the total area.
According to basic natural-geographic characteristics, Velika Kladusa area belongs to peripanonic
space, situated between Dinaride mountain chain
on south-west and low Posavina in the north, with
the average altitude above sea level of 300 to 400
meters. The karst relief shapes are reflected in a
number of funnel-shaped holes in limestone, sinkholes and still unexplored caves. The municipality
is very rich in preserved sources (wells) of drinking
water, as well as wells of thermal water that can be
used for health and recreational purposes.

METHODOLOGICAL
APPROACH
2.1. General approach to audit
process
This assessment of initial state of practices for reduction of NRW in Vodovod i kanalizacija Velika
Kladusa is based on several main sources of information: data from application form, data from
questionnaire for pilot water supply companies,
presentation of the company prepared for the second training for technical staff, data gathered during field inspections and discussions with key employees of the company, earlier prepared reports
and documents for projects of international donors and financial institutions, existing literature
and experience of involved regional NRW experts.
2.2. Field visit
After Vodovod i kanalizacija Velika Kladusa submitted its questionnaire for pilot companies, it was
reviewed by the experts. On 25 August 2015 experts of Aquasan network in B&H and an external
expert for NRW visited the company and the said
questionnaire was supplemented at that occasion.
They also discussed with company management,
losses detection team and GIS, and visited telemetric center and warehouse, as well as proposed
pilot zone.

INSTITUTIONAL
ASSESSMENT
3.1. Legal frame and organization
PUC Vodovod i kanalizacija Velika Kladusa is a
public company organized as limited liability company owned by the municipality, with the primary
activity in water supply and collection of wastewaters in the municipal area. The company was
established in line with regulations of valid laws
(Law on economic subjects, Law on public companies), and all founding acts of the company are
harmonized with the said laws. Company activity
is harmonized with regulations of valid laws and
corresponding bylaws (Law on communal activities, Law on water), as well as with decisions of
municipal council. PUC Vodovod i kanalizacija
Ltd. fully implements previously said regulations.
Company management consists of general
manager, head of legal department, head of finance
and accounting and head of technical sector. General Manager is selected through a public competition, and the proposed candidate is confirmed
by the Mayor. The company has all the foreseen
bodies, such as Assembly of the company, Supervisory board, Audit board, etc. There is no particular
agreement regulating mutual rights and obligations between the company and municipality of
Velika Kladusa, their mutual relations are currently defined only by the Decision on establishment.
Ownership over the company
property
Unlike most water supply systems in FB&H, where
the system is owned by municipalities, in Velika
Kladusa water supply system is owned by the water
company. Other movables and fixed assets are also
owned by the company. Water supply company
acquires property through its work and developments, from own resources, as result of own business activity, taking loans, donations, etc. Rapid
post-war expansion of water supply system of Velika Kladusa was realized through joined acting
and investments of the water company, municipality and citizens.
Annual planning
PUC Vodovod i kanalizacija Ltd. Velika Kladusa
has and implements its business plan, which is being prepared for the forthcoming year at the end
of the current year. This plan is adopted by the
Supervisory board and Company assembly. Annual business plan encloses planning for particular
departments of the company and for main business activities. It contains main planned priorities
of the company for the coming year, financial plan,
and investments plan. Necessary budget is defined
for all planned activities. In terms of accounting,
the activity of water supply and activity of collection of wastewaters have separate accounts per activity, which gives a quality overview of business
per activities. In line with public procurement law,
the company also makes a plan of procurement for
the coming year, which defines procurement of individual goods and services for planned activities.
Analyzing business activity in the last three
years, the company had positive balance in two
years, while one year was negative. With the current price of services the company cannot secure
viable business. At the request of the company the
municipal council is considering change of price
of communal services, which often leads to political interference and makes company business
difficult.
Reporting
At the end of each business year, the company creates a report on the work for previous year, which
needs to be approved by the Supervisory board
and Company assembly. This report is then directed to the municipal council of Velika Kladusa,
where it is presented by the general manager of the
company, after which it is sent for adoption by the
councilors. The report mainly comprise of data on
realized revenues and expenditures, financial indicators, business analysis, data on the technical sector, data on the development and research sector,
work of the Supervisory board and the situation
on human resources in the company, as well as the
report on water losses and NRW.
Organizational chart
The following diagram shows the organizational chart of the water supply company in Velika
Kladusa.
Human resources
PUC Vodovod i kanalizacija in the last year had
a trend of decreasing number of employees, currently 51, which makes 3,64 employees per 1.000
connections. The company has a training plan for
employees at company level, and they spend, in
average, 5 days on training per year. At this moment the most necessary training is for GIS and
losses detection. The company management is not
satisfied with the current training offers and possibilities for the employees to be additionally and
continually educated. They believe such trainings
should be organized through national associations
of water companies.

3.2. Commitment of company
management to reduction of
NRW
Current level of non-revenue water in public
water supply system of Velika Kladusa is 53,4%, or
in quantity, 2,004,548 m3 per year. The company
does not have an action plan for detection and
repair and reduction of NRW. Regarding project
activities in 2007 and 2009 (zone 1), there were
activities of reduction of losses in zone DMA 3,
implemented by the Hydro-technical Institute
from Sarajevo. After that no other detection activities were conducted, except the passive detection,
i.e. repair of visible or reported damages. The reason for this is that PUC Vodovod i kanalizacija
Ltd. does not have the functioning equipment for
implementation of necessary activities. A part of
the equipment was procured through EU donation, but due to inadequate service the equipment
is not in functioning state, and there is no sufficient training of employees to work with that
equipment.
Nevertheless, recognizing the significance of
this field and a new, modern approach in business, the company management started establishing teams for detection of losses and GIS over the
past year. Also, the company lately actively participated in regional projects of asset management
and benchmarking.

Source Slapnica was made between 1986 and
1987. It consists of one well.
Source
Zboriste is currently the only collector-well in the water supply system.
4.1. Assessment of technical
management
Characteristics of water supply
infrastructure
Water sources
The water supply system of Velika Kladusa
currently captures 260 l/s, while the maximum
available quantity is 412 l/s. The characteristic here
is that these are usually drilled wells of high depths
(up to 620 m), and some of them have warmer
water of up to 28 °C. Speaking of water treatment,
there is only chlorine disinfection since the water quality is satisfactory and there is no need for
further treatment. The water is currently being
captured from 6 separate sources:
Source Kvrkulja was made between 1974 and
1978. The source consists of three active wells.
Source
Dabrovine I was made between 1979
and 1985. The source consists of three wells,
from which only well B1 is currently active.
Source
Dabrovine II was made in 1983 and
consists of two wells of which well B1 is currently active.
Source
Sumatac is in the settlement of Purici, 12 km south-east of Kladusa, alongside the
road Velika Kladusa – Cazin, and it has one
exploiting well.

For easier managing and analysis, the system
is divided into 11 water supply zones with average pressure is 4 bar, minimum 1,5 bar and the
maximum pressure is 16,0 bar. Due to the location
of sources and demanding terrain configuration,
there is 100% pumping of water in the system towards the consumers, as follows:
of consumers are supplied by one
pumping,
Documentation on water supply
network and facilities
Water supply company has referenced digital cadastre maps, with displayed public water pipeline
network and corresponding facilities (reservoirs,
wells, main shafts, etc.) in DWG (AutoCAD format) and basic information on them.
58%
39%
of consumers are supplied by two
pumping,
3%
of consumers are supplied by three
pumping.
For this purpose 8 pumping stations are
used daily at water sources, along with 8 booster
pumps, which creates significant electricity bills to
the company (about 19.000 Euros).
Municipal coverage with clean drinking water
is 95%, which understands some 35.000 inhabitants. Highly sophisticated equipment results in
very clean and daily controlled water. Total length
of water pipeline is some 650 km of different profiles, which caused high financial investments and
high maintenance costs. The following table gives
an overview of pipeline per material extracted
from GIS, which encloses approx. 70% of network.
In the past two years the company has been
actively participating in asset management project within Danube water program. Within this
project we started creating GIS database in QGIS
software, and presently some 70% of water pipeline has been inserted into the GIS.
The company does not have hydraulic model
of the system, or any of its components.

Managing the water supply system
Telemetric center, equipped with modern SCADA
system, is the control and monitoring center. It
follows the functioning of the whole water supply system of Velika Kladusa – all 5 independent
but interconnected subsystems, which means daily monitoring of: water flow, pump work hours,
pump Amperage (electrical consumption), water levels in reservoirs and other indicators on
the program. We should point out here that all
objects and facilities are covered with telemetric
management, whereas some object lack flow meters. System of remote supervision and management of water supply in Velika Kladusa secures
the following:
Reliable
collection, processing and storing of
information on the state in individual water
supply objects, network, production and consumption of water;
Simple
and user-friendly display of collected
This telemetric system, after years of use,
proved to be very reliable, purposeful and justified, without mistakes in work and with possibility
to save electricity in work of pumps, and monitoring the whole water supply system. Work on telemetric system has been performed in four shifts,
by four workers.
Besides the aforementioned, the company
continuously works on regular inspection of objects in the system: Pump and chlorine stations,
booster stations and reservoirs. Although there
is only passive detection of malfunctions, with
regular monitoring of telemetric system the water
supply company notices increased consumption in
particular parts of the system, and based on that
makes inspection and possible intervention. There
was a huge number of repaired malfunctions in
2014, 1626 cases with average intervention time
of 1 – 2 days.

Total consumption (delivered water / number of
consumers) according to submitted data of the water supply company is 131 liters/head/day.
Besides, there was water consumption analysis
made in pilot DMA zone 4, in a way that 14 households were selected randomly in different parts of
the DMA zone, with exact number of persons in
the household, and we recorded the water consumption for selected households in 2014. Two
household on opposite ends of the scale (highest
and lowest consumption) were deleted from the
calculation, and based on the remaining 10 we
calculated a specific water consumption of 162,7
lit./head/day.
The difference between the specific consumption for the whole system and the pilot zone is partially caused by the fact that a number of Velika

Comment
Kladusa inhabitants temporarily reside abroad.
Another reason is that DMA zone 4 is a rural area
where water is used for watering the gardens and for
the cattle. However, the value obtained in this way is
a lot more realistic, since it shows real consumption
of the people who really reside in that area.

The water supply company has submitted a
proposal for increasing service prices to municipal
council of Velika Kladusa for approval, however,
municipal council often does not approve such
requests, which creates difficulties in functioning of the company. In Bosnia and Herzegovina
there is no set methodology of forming the prices
of water supply companies’ services, creating difficulties to these companies to reach the market
service price. Basic sources of finances for the
company are services of water supply and collection of wastewaters.

Consumer’s water meters are read each month,
followed by invoicing and distribution of bills,
which are collected at a rate of 92%. Consumers
are divided into three categories with different service price. The following table gives an overview
of water prices and basic indicators of financial
activity for 2014
Financial activity is made in line with valid
national and international accounting standards.
For this purpose we use accounting software ‘PIS’
by Infosys, dedicated and specialized to enclose all
segments of work of water supply and communal
companies.

CONCLUSIONS,
RECOMMENDATIONS
AND KEY ACTIONS
Recommendations and key actions
Based on field visit there are recommendations
and activities defined that the company needs to
implement to the aim of reduction of NRW:
General conclusion
Short term (within one year):
Based on field visit to PUC Vodovod i kanalizacija
Ltd. Velika Kladusa it can generally be concluded
that it is one of better water supply companies in
the area of B&H. In support to this are the data on
large coverage of municipality with public water
supply system, high percentage of collection, positive financial results, adopted work standards, etc.
The company is active in the work of national association of communal companies and in various
regional projects, where it is actively included and
ready to present its good practices.
Acquiring
at least basic set of detection
equipment with corresponding practical field
training,
Introduce
a procedure of regular creation of
water balance, as for the whole water supply
system, also for the particular DMA zones,
Complete
inserting water supply system into
the GIS, with DMA zone 4 as the priority zone,
In
On the other hand, the company did not realize significant improvements in reduction of
NRW, which presents one of the weakest links in
its work. Recognizing this shortcoming, in the past
1-2 years the company undertook establishing and
equipping teams for detection and elimination of
losses, and GIS. Their equipping and initial activities are going rather slowly due to lack of necessary equipment and necessary knowledge of the
employees. Employees engaged in activities of this
project execute their agreed obligations with quality and in time.
its financial annual report the company
should have a chapter on NRW for the current
year.
Mid-term (one to three years):
Create
a detailed action plan of reduction of
NRW,
Introduce
active detection of losses by monitoring consumption in defined DMA zones
with implementation of necessary activities
and measurements, to the aim of reducing the
high percentage of NRW,
Start
procurement and installment of flow
meters where they are lacking in objects
(pump stations, booster stations, reservoirs)
and zones,
Commence with activities of creating a hydra-
ulic model of the WS system,
Continue strengthening human and technical
capacities of already formed GIS team and detection of losses team.
Long term (over three years):
Establish procedures of continual updating of
existing cadaster of water network in GIS,
Continue
with started activities of asset management and benchmarking,
Perform
additional expansion and equipping
of SCADA to lacking objects, with the aim
to cover all the zones with flow and pressure
measuring.
