T K Services
Unique Abilities
Surely anyone can install a sewage system? Maybe? Let’s find out....
T
he simple act of installing a new sewage system
requires a little more effort than just digging a
suitably sized excavation and dropping the right
tank into it. In many cases it can take several months of
liaising with Regulatory Authorities to acquire the correct
approvals to allow the work to begin in the first place.
Private Sewage Systems
All discharges into ground need to be approved by the
Environment Agency so that they can carefully control the
environmental impact of the scheme. The application
process for a Consent to Discharge Licence can take up to
four months. But before the application form can be
submitted a proposal must be drawn up to provide an
acceptable solution.
This is where T K Services unique abilities begin to show
their true worth. Our experience in dealing with the
Environment Agency enables us to design a scheme that is
more likely to meet with their approval and thereby reduce
the amount of time taken to issue the licence.
Connection to a Public Sewer
Often a property can be connected to the public sewer by
way of a sewage pumping station. A pumping station can be
used to replace an old private sewage system if the public
sewer is close enough to make financially viable.
Firstly, and most obviously, permission must sought from the
owner of the public sewer before a connection can be made.
This is very often the easiest hurdle to clear and can be
agreed in a matter of days.
However, most public sewers are located in the public
highway and this is where it becomes a little more involved.
Before any work can commence in the highway the
contractor must apply for a Street Works Licence from the
local Highways Agency. As part of the application process
we must write to all of the utility, telecoms and pipeline
companies so that they can provide us with details and
drawings that indicate where their apparatus is positioned in
the highway. For each scheme we may have to write to
almost thirty such companies, which is why we have staff
dedicated to applying for the details and chasing up the
responses to ensure that we experience minimum delay at
this crucial stage.
Once all of the replies are returned we have to interpret them
to ensure that there is a safe route for the pumped sewage
main that we wish to install. Once a safe route has been
established we must then submit an application form together
with proof that we hold adequate insurance, our engineers
are qualified to work in the highway and hold valid
Supervisors and Operators certificates together with a traffic
management proposal, method statement and risk
assessment for the scheme. We must also demonstrate that
all waste will be disposed of in a responsible manner.
So what makes T K Services unique?
Well, there are not many of our competitors that will take on
the entire scope of work that is required to get a scheme from
original concept through to an operational system. Perhaps
understandably for some, getting the relevant approvals
requires too much effort and so they put that responsibility
back on the client.
We believe that our job is to make the whole process as
painless as possible for the client. Yes, we will need
information from you in order to complete the applications.
But we will deal with all of the correspondence on your
behalf. All necessary site meetings will be carried out by our
team. That is not to say that you will be excluded from the
proceedings. We welcome your involvement and will keep
you fully up to date with any developments.
We have also pioneered the use of trenchless technology to
install pumped sewage mains in order to minimise disruption
in the highway and to help reduce costs.
So, can anyone install a sewage system? Well, maybe? But
maybe the question should have been whether they can get
the approval to begin the installation in the first place?
T K Services
Installation
Sewage disposal systems nearly always require some kind of civil engineering work.
Naturally, because of the type of installation, work on sewage systems needs to be
carried out to a very high standard.
T
K Services offers a full, prompt and efficient
supply and installation service. Your treatment
plant, septic tank, pumping station or cesspool is
installed to the manufacturer’s specification by people who
specialise in the below ground installations which these
projects require.
On site our installation team ensure that your project is
completed on time and in good order. Work is complete
when one of our commissioning engineers have connected
and tested the units for you.
As well as being approved by WPL to supply and fit their
full range of products we can specify systems from most of
the major manufacturers in accordance with the clients
requirements. We are confident that the work we
undertake is completed to the highest standard – our
previous customers have told us so.
We operate one standard of quality only. We apply the
same level of expertise, commitment and attention to detail
to every project regardless of size.
Before giving you a quotation one of our engineers will visit
your site to assess the specific site conditions. He will then
prepare a detailed quotation for your approval, and advise
and obtain any permissions and consents required.
All of our installations are completed in accordance with
Environment Agency requirements and building control
guidelines. We use only the highest quality materials and
our methods of construction ensure that we do not
experience problems with faulty workmanship. By working
closely with our customers we minimise the disturbance to
their daily routine that can arise from drainage works. Upon
completion we aim to leave your premises as tidy as
possible and if you wish we can arrange for any
landscaping work that may be required.
If you wish to install your plant yourself or if the installation forms part of a
larger contract, we will be happy to provide all the assistance you require.
We can advise on: plant suitability and location; licences, permits and
consents that may be needed; installation and commissioning requirements

T K Services
Servicing
Professional service for your peace of mind.
All sewage treatment plants and pumping stations have
electrical and mechanical components that will benefit from
regular maintenance. The T K Services Service
Department offers a wide range of Service Agreements that
can be tailored to match your precise requirements. We can
include related equipment within the scope of a contract
including grease traps.
Our service engineers have over 25 years experience in the
industry and are fully conversant in servicing all types of
sewage treatment plants and pumping stations. In addition
our computerised systems ensure that your regular service
visits are never missed. After each visit you will receive a
detailed report on the condition of your system together with
recommendations for any additional works that may be
necessary.
Before a Service Agreement contract is entered in to, we will
provide you with a detailed quotation pack, which includes
Service Schedules for your particular system so that you will
know what work will be carried out at each visit. One of the
most common causes of problems with sewage treatment
plants is incorrect emptying of the sludge in the primary
settlement tank. We can arrange for our service visit to
coincide with your tanker so that we can supervise the
procedure to ensure that it is carried out correctly.
In our experience a properly maintained sewage system will
provide greater reliability and will more consistently achieve
the water quality limits set out in your Environment Agency
Consent to Discharge. Regular servicing also helps to
reduce or eliminate expensive repair bills that occur as a
result of complete plant failure.
We keep stocks of the most common spares so that should
the worst happen, your system will be back in full operation
as quickly as possible. If you have lost your Operation &
Maintenance manual then we can provide replacements for
most types of system.
EMERGENCY CALL OUT SERVICE
If you experience difficulty with your system and require a
service visit then a quick call to our Service Department
should be your first move. We will endeavour to get an
engineer to you as quickly as possible. Service Agreement
customers enjoy a 15% discount from our standard service
rates.
REPAIRS AND UPGRADES
As well as routine service work, our Service Department is
responsible for all types of refurbishment work from minor
repairs to major rebuilds. We aim to carry out any works as
quickly as possible and will always try to work around your
time requirements.
Some older systems may benefit from some of the latest
developments. We have improved many systems by fitting
updated components to prolong their service life. In some
cases a new control panel can improve the reliability of the
system and in other cases a new distribution system can
improve the efficiency and performance. Each system is
assessed individually, taking into account all factors that can
affect its overall performance.

Previous
Projects
If a picture speaks a thousand words…...
Over the years we have been involved in a number of highly prestigious and varied projects. Every day there are
thousands of people all across the country are relying on a sewage system that has either been supplied or installed
by T K Services.
We have installed sewage systems for well over 1,000 homes, many of these being single dwelling sewage
treatment plants similar to some of those shown here. As you can see we make every effort to ensure that they are
as discrete as possible.
Many businesses have also benefited from our particular expertise. We have installed sewage treatment plants,
pumping stations and grease degradation systems to suit various applications ranging from small industrial units to
shipbuilding yards and from small restaurants to pubs, hotels and golf courses.
The small number of projects represented here demonstrates
our flexible approach to a variety of applications. Ranging in
size from systems that serve two or three residents to ones
that serve thousands of visitors or workers.
In most cases a completely new system is installed discretely
below ground. But occasionally an existing system can be
incorporated into the design and share the overall load. On
two occasions we have even installed new sewage treatment
plants above ground: the first was installed at a ship builders
yard in North Devon and was designed to be relocated as the
site expanded. The second was installed on the edge of an
estuary and was pump fed to avoid the high water table. We
have also installed systems for adoption by the local Water
Authority.
Experience has taught us that
each installation is unique and
our policy is to apply the same
level of commitment and
attention to detail to all of our
installations regardless of size they are all important to us.

Why use a Pumping Station?
The Prestige Foul Water Pumping Station Range is designed to pump
the raw effluent that is discharged from homes or business premises.
They use two high-quality submersible sewage pumps, operating on a
duty/standby basis via a local control panel.
Its cylindrical shape and concrete construction make it exceptionally
strong. All Prestige foul water pumping stations are constructed from
the highest quality components, including the use of stainless steel
fittings throughout.
Chamber Design
The pumping station chambers are engineered to high standards and
manufactured in either durable GRP or concrete ring sections. All
connections, both inlet and outlet, and tank capacities can be adapted
to suit individual site requirements.
When specifying a GRP chamber the package comes pre-assembled,
enabling it to be delivered to your site ready to be installed in a prepared
excavation. It is then a simple matter to fit the pumps into the chamber
and to mount the control panel into its housing before commissioning.
If you select a system that is constructed from concrete ring sections,
most of the assembly is carried out on site as part of the installation.
Because of this the system design is much more flexible and the
finished product precisely matches your unique project requirements.
All of our packaged pumping stations are supplied with controls which
enable fully automatic operation. Most models are also equipped with a
high level alarm.
Pump Selection
We use a wide range of submersible pumps, predominantly from the
ITT Lowara, KSB and Flygt ranges – all are well known for quality.
These include macerator, grinder, solids handling and clean water
pumps. A full range of flow and discharge head characteristics allow
you to specify the control of discharges from most sites.
Installation
Pumping stations can be incorporated into the design of any private
sewage treatment plant. This can be particularly helpful when drainage
inverts are deep or when it is necessary to control fluctuating loads.
T K Services provide a full supply and installation service for
pumping stations and rising mains. This service includes liaising with
local authorities and public and private utility companies to obtain the
relevant permissions and licences. Where possible we will use the
latest trenchless technology to lay the rising main in the highway to
reduce costs and minimise disturbance.

How the Pumping Station Works
The incoming sewage is held in the sump of the pumping chamber.
When it reaches a predetermined level it triggers a float switch, which in
turn activates one of the pumps. The pump keeps running until the level
drops below the ‘stop’ float switch. This sequence continues with each
of the pumps operating alternately to ensure even wear and tear.
In the unlikely event that one of the pumps develops a fault then an
alarm is triggered and the second pump operates to ensure that system
doesn’t stop running. If for any reason the water level within the
chamber reaches the ‘high level alarm’ float, then both pumps are put
into operation and the alarm is triggered. Once the water level drops
sufficiently the alarm will turn off.
BUDGET OPTION
For smaller sites or where cost is a major consideration, a single pump
system can be specified. No control panel is necessary as the pump will
be controlled by its own integral float switch.
PLANT DESCRIPTION
Pumping Chamber
The chamber is generally constructed using 1,200mm diameter
concrete rings to a depth of 1,450mm below the incoming drain.
However, larger chamber sizes can be specified. We can also supply
pre-assembled GRP or plastic chambers upon request.
Pumps
We usually select two submersible sewage pumps from the extensive
ITT Lowara range. The pumps are mounted on guide rails for fast and
easy removal.
Pumps from most of the major manufacturers can also be specified,
including Flygt, ABS and KSB. All types of waste can be
accommodated from surface water to raw sewage.
Internal Pipework
The majority of pipe work and fittings are made from 50mm diameter
ABS, which is connected to the discharge pipe via a MDPE to ABS
adaptor. The 2” ball-type non-return valves are manufactured from cast
iron. All stations incorporate an isolation valve on the discharge pipe to
facilitate easy future maintenance.
Level Control
We install four high-quality sewage grade float control switches. The
lowest of the switches stops the pumps running to protect them from
running dry. The middle two floats initiate the start of each pump cycle.
The highest of the floats triggers the high level alarm and activates both
pumps.
Control Panel
The control panel is a standard duty/standby unit with a built in highlevel alarm facility. It features a main isolator, which is mounted on the
door along with status indicator lights and hand/off/auto switches for
each pump.
Electrical Requirement
Can be specified with either a single or three-phase power supply.

Air Diffuser (4)
Settled Solids (5)
The Diamond system consists of two treatment chambers within a single tank.
The centre aeration chamber (1) is a circular tank with a
sloped open bottom, which empties into the bottom of
the outer clarifier chamber (2).
Gravity causes the aerated solids to settle back to the
bottom of the tank where they are again drawn back up
through the draft tube.
Located in the centre of the aeration chamber is a
200mm diameter draft tube (3), which extends to 100mm
from the bottom of the clarifier. Air is released at the
bottom of the draft tube through a disc plate diffuser (4).
As raw sewage enters the aeration chamber, it displaces
biological solids from the aeration compartment to the
clarifier. Quiescent conditions in the clarifier allow the
digested solids to settle to the bottom of the clarifier
where they are returned back to the aeration
compartment.
As the diffused air rises in the draft tube, it causes an
upward flow of process fluid. This draws the settled
solids (5) from the bottom of the clarifier up through the
draft tube where they are discharged at the surface of
the aeration chamber.
The design of the draft tube ensures continuous and
complete mixing of oxygen with the sewage. This allows
for the growth of various aerobic organisms that
biologically degrade the wastewater contaminants.
The clarified (treated) effluent flows slowly up through
the clarifier and over a weir (6), which extends around
the periphery of the tank.
The effluent collects in an outer trough where it is
discharged through a 110mm-pipe connection. The
scum baffle (7) located inside the overflow weir prevents
floating solids (8) from passing over the weir.

Low maintenance and whole life costs
Treats to the highest standards ie 10:10:3 BOD:SS:NH4
Unique Flow balancing primary tank
Copes with variable flows and loads
Reliable operation with standby facility
Each plant designed to customer requirements
Process Description
After primary settlement the influent
flows under the gravity to a number of
treatment modules arranged in series.
A submerged bed aerated filter by
design, the module is split into several
chambers, each filled with high voidage
plastic media. Within these chambers,
both carbonaceous and nitrifying
processes take place. Air to oxidise
the influent and to scour excess
biomass from the filter media is
introduced continuously below each
chamber by a series of diffusers. Each
diffuser is capable of being removed for
maintenance, without the necessity to
shut down the plant.
The package treatment plant consists of a primary
settlement tank, biological treatment module, secondary
(humus) settlement tank, all fabricated in GRP and
designed for below ground installation. The plant is fitted
with large, gas strut assisted covers to give full access to all
parts for maintenance and desludging. The package plant
is also supplied complete with duty only air blower and
control panel housed in a GRP kiosk, and 10m lengths of
air hose.
Following biological treatment the effluent flows into the
secondary (humus) settlement tank where the excess
biomass settles out. This tank is designed for an overflow
rate of 0.9 m/hour at full flow to treatment. It is equipped
with air lift pumps which are arranged to periodically and
automatically, transfer settled humus sludge to the primary
tank for co-settlement.
The primary settlement tanks are designed in accordance
with BS 6297, where it is anticipated 30% of the BOD load
will settle out and there is sufficient volume for sludge
storage. The primary settlement tank is equipped with
baffles to prevent any floating scum entering the biological
phase of the treatment, and with WPL’s unique forward
feed system, which lowers the level in the tank during
periods of low flow to provide a balancing volume for
possible surges in the influent.
Air to oxygenate the effluent in the biological treatment
chamber and operate the various airlifts is provided by a
duty only air blower that is housed in an accoustic lined
GRP kiosk.
The treated effluent flows under gravity to the works outfall.
A Form 1 control panel, also housed in the GRP kiosk,
automatically controls the operation of the plant.

Other Waste
Water Products
Grease Traps
Storm Attenuation Tanks
We offer a range of grease traps for the interception of
catering fats prior to discharge to the mains or private
drainage system.
A range of storm attenuation tanks are available for storm
water management. Single module units up to 240,000
litres capacity are available, or multi-module using
interconnecting low level balancing pipes.
Units can be supplied with an automatic enzyme dosing
system, which digests the grease content converting it into
carbon monoxide and water.
Septic Tanks
Tanks can be supplied with integral stainless steel
hydrobrakes or pumped discharge for sites where a gravity
system is not possible. Due to the bespoke nature of the
products these systems are available only on a made to
order basis.
A range of three-stage septic tanks are available to suit a
number of applications and differing ground conditions.
Septic tanks are less common now due to increased
awareness of the risk of pollution. However, in some
circumstances they remain a cost effective way of providing
private drainage.
Cesspools & Storage Tanks
For the containment of many different types of waste, for
sites where discharge is not possible due to environmental
constraints, we offer a comprehensive range of sealed
Cesspools
Silt Traps
As the name suggests, this product intercepts silt from
vehicle wash down areas and is often used in conjunction
with a full retention interceptor prior to final discharge.
The Acorn Silt Trap is supplied with a hinged open mesh
steel cover allowing the free flow of contaminated water
into the unit. Discharge is via a single outlet connection.
Bypass Separators
Class II
The Acorn range of petrol/oil Bypass Separators have been
designed to intercept and treat the surface water run off
from large impervious areas, which provide a low risk of
hydrocarbon pollution.
Similar to Class I design only without the coalescing filter –
discharge from Class II units is normally to the foul drain.
Full Retention Separators
Acorn offer a comprehensive range of petrol/oil Full
Retention Separators for sites where there is a high risk of
hydrocarbon pollutants contaminating the surface water
drainage system. The design of the separators relies upon
gravity separation and minimum retention periods within
the selected unit.
Light Liquid Separators
Class I
The Acorn Class I Light Liquid Separator incorporates an
automatic closure device – ACD – and a coalescing filter.
The separator is designed such that should the separator
become full of pollutant then the ACD closes down the
discharge, therefore retaining the contaminates within the
separator. The coalescing filter intercepts the smaller more
buoyant globules of pollutant which remain in suspension
and prevent their discharge. This ensures that these
systems achieve a high quality discharged effluent.
We offer an oil/water interface detection system providing
maintenance/ management information to the operator.
As you can see from this
selection we offer a product to
suit any application.
In
conjunction with Acorn’s design
flexibility we can provide custom
built products at very reasonable
prices. There is no reason why
you should not use us to the
supply the equipment for your
next project.
Our policy, and that of Acorn is to
provide solutions to problems.
Not to simply sell you a product
that may not be necessary. We
believe that in the long run we will
develop a much stronger
relationship with our customers
that is based as much on trust as
on the quality of the service that
we provide.

Mini Guzzler
A class-leading solution to maintain clean, free-flowing kitchen drains.
Suitable Applications
Normal/shallow-gradient drainage pipes running
directly into the main sewer
Features
Coats drain pipes with an eco-barrier that prevents
grease from forming, so preventing the main cause of
blockage
Eliminates foul odours caused by rancid grease
Improves hygiene: grease in drains is a haven for
rodents and insect infestation
Fully automatic, requiring no user maintenance - just a
simple, weekly operating check
Highly economical: precise product metering stops
wastage
Totally safe and environmentally responsible
The need for grease treatment
Cooking oils and fats usually appear so innocuous while in use that it
can be hard to comprehend the extent of their transformation once cold
and contaminated. Left unchecked, grease will build up in even the best
designed drain. The early symptoms are foul and rancid smells, until
eventually blockage results.
The Grease Guzzler prevents these problems - keeping drains
odourless and free running at even the most problematic of sites.
All the chaos and expense of manual grease-blockage clearing is
eliminated, while the need to empty messy and unhygienic grease traps
is reduced enormously!
How the Mini Guzzler works
Twice a week, at regular and pre-programmed times, Mini Guzzler
releases a unique biological cleaning solution into the drain line. This is
produced from a concentrated 'bio-compound', 'S-10', which is stored
within the machine. Once in the drain, the S-10 solution sets about
developing a bio-film coating along the length of the pipe run to provide
continual blockage protection. Mini Guzzler has no rival.
What is S-10 Bio-Compound
S-10 is a harmless, living medium comprising naturally occurring, nonpathogenic enzymes and micro-organisms in a dormant spore state. Its
formula is unique to WPL.
S-10 is a surprisingly robust product; demanding no special
requirements in its handling or storage, save that it should not be
frozen.
The secret of S-10
Many of Mini Guzzler's unrivalled benefits result from the exclusive
formulation of S-10. Throughout the development period, WPL carried
out extensive tests on other bio-compounds and found none that
performed consistently to its criteria. The winning attributes of S-10 lie
principally in its physical composition, which enables the application of
‘bio-fixation’ technology - meaning that the active content, I.e., the
microbes, are integral rather than just a surface coating. As a result, the
lining that it forms on the drain pipes is less vulnerable to harsh flows
that may pass by, such as bleaches or detergents. The only part lost is
the surface layer, with all the rest remaining intact, enabling the bioproducts to reproduce to repair the damage.
How S-10 works
The drain coating formed by the S-10 culture is active in two ways.
Firstly, it prevents grease build-up along the drain run by attaching itself
to any deposits that land, sloughing off to keep them in suspension.
Secondly, it leeches onto and attacks existing deposits of congealed
grease, reducing them steadily until the pipes are clean. Heavily greasecongested drain pipes should be cleared manually by rodding or jetting
before installation of Mini Guzzler to prevent the risk of blockage from
the loosening of large grease chunks.
WPL strongly recommends that no other bio-compound is used in the
Mini Guzzler system. However, the biotechnology marketplace supports
constant development and, should you encounter an apparent equal to
S-10, we would be happy to test and approve it, provided we are
satisfied that it meets claimed performance.
Where should Mini Guzzler be installed?
Mini Guzzler is suited ideally to internal wall mounting, normally in the
kitchen, close to the drainage waste pipe. Connections are very simple cold water and electricity in, drain access out.
For optimum results, Mini Guzzler should dose as close to the drainhead as possible. In all cases, dosing should occur close enough to the
last sink or drainage discharge point so that grease cannot solidify in
pipework upstream; whilst far enough downstream for the bio-products
to be working within their optimum temperature range, 27-43 degrees C.
Will Mini Guzzler control all oil, fat and
grease wastes?
Yes! Although these products appear quite different to each other in use, at
molecular level they are all fundamentally similar. Mini Guzzler handles
them all equally effectively.
Food scraps
Food scraps and peelings should be prevented from entering the drain.
This is most simply done using a simple mesh screen installed at the drainhead. Their presence will not in any way hinder Mini Guzzler's greasetreatment performance, but their continual build-up can prove of no benefit
to the drainage system as a whole.
Detergents and chemicals
The bio-products are surprisingly hardy in the face of detergents and
chemicals. Nonetheless, the culture can be destroyed by their
indiscriminate use and care should be taken wherever possible. Bear in
mind that with Mini Guzzler installed, the need for harsh drain-cleaning
chemicals is eliminated.
Service and maintenance
The Grease Guzzler has been engineered for complete reliability.
Absolutely no user maintenance is necessary. In order to keep kitchen
disruption to a minimum, a six monthly supplier service/refill programme is
all that's required. This will be managed and undertaken directly by your

which you can depend.

Totally safe and environmentally responsible
The need for grease treatment
In an environment where cooking oils and fats are used in large
quantities, it is often difficult to imagine the high volume of
grease that finds its way into the drainage system. Grease build
up can be problematic even to the best designed drains.
The most commonly associated symptoms are an increased
sight of vermin and insects and the presence of a foul and rancid
smell, which becomes unpleasantly potent in the warm weather.
The final and most costly indication of grease build up is a
blocked drain.
The Grease Guzzler’s patented design and unique bio-formula
will eradicate existing grease build up and also prevent it from
re-occurring, even in the most problematic of sites.
How the Grease Guzzler works
At a pre-programmed time, usually once a day, at a regular and
pre-programmed time, the Grease Guzzler releases a unique
biological cleaning solution into the drain line. This is developed
within the machine from a concentrated 'bio-fluid' formulation
called S65.
Each cycle begins with a dose of S65 bio-fluid concentrate into
the incubation tank filled with cold water. The tank is gently
heated for eight hours to stimulate the micro-organisms to
multiply, resulting in the creation of a rich soup of grease hungry
bacteria.
WPL’s patented S65 bio-fluid concentrate
S65 concentrate, is a derivative of over six years research and
development into biological grease management. It comprises
of a purposely selected and naturally occurring cocktail of nonpathogenic enzymes and micro-organisms, forming a mixed
culture composite. This improves the Grease Guzzler’s ability to
combat many different forms of grease that are commonly found
in commercial kitchens.
The formula has been designed to be hardy when faced with
certain detergents and chemicals. However, care should be
taken as S65’s complex culture can be damaged or even
destroyed by their indiscriminate use.
Please note that with the Grease Guzzler installed in your
kitchen, the need for harsh drain cleaning chemicals is not
necessary.
How S65 works
S65 uses two simultaneous processes. Enzymes make the first
assault, breaking the grease into simpler food particles, which
are edible to micro-organisms, these then digest and degrade
the grease further. As the hungry micro-organisms grow, they
reproduce rapidly by splitting, which at the same time releases
more enzymes to perpetuate the process until all the grease is
broken down
The result is the conversion of the grease into fatty acids and
glycerol; water soluble products that form an emulsion. Harmless
in the drain, this transformation is irreversible. As these products
continue their way to the treatment plant, their degradation
continues until, ultimately, the grease is broken down fully into
carbon dioxide and water.
Where should Grease Guzzler be installed?
The Grease Guzzler should be selected where the drainage run
to be protected includes either grease traps or pump stations, or
terminates at an on-site, private sewage treatment works.
It is suited ideally to internal wall mounting: normally in the
kitchen, close to the drainage waste pipe. Connections are very
simple - cold water and electricity in, drain access out.
Dosing should occur close enough to the first sink or drainage
discharge point so that grease cannot solidify in pipework
upstream; whilst far enough downstream for the bio-products to
be working within their optimum temperature range, 30-35
degrees C.
Is the Grease Guzzler a fussy eater?
No! The Grease Guzzler degrades all waste oils, fats and grease.
Although these products seem quite different to each other, at
molecular level they are all fundamentally the same.
Food scraps
Food scraps and peelings should be prevented from entering the
drain, by installing a simple mesh screen at the drain-head. If
allowed through, the bio-products will happily 'eat' the scraps, but
this may diminish their concentration around the grease.
WPL does not recommend the use of garbage grinders. These
simply macerate the scraps into a pulp, increasing their surface
area and providing an even more attractive food source for
microbes.
Grease Guzzler and package
treatment plants
Installation of Grease Guzzler upstream of a package
sewage treatment plant (i.e. at an establishment not
connected to mains drainage) will yield significant benefit to
plant operation. Grease is as much of an enemy here as it is
anywhere, and its presence will always have a detrimental
effect. However, once irreversibly pre-treated, grease can no
longer solidify to impair efficiency. Additionally, its final
degradation, to carbon dioxide and water, requires less
dissolved oxygen than it otherwise would, and thereby helps
further to maintain a better operating system.
An additional benefit is currently under close investigation.
Feedback from field trials has suggested that plant
desludging intervals may be extended considerably with the
installation of Grease Guzzler. The precise reasons for this
have yet to be demonstrated and, as yet, we have no
quantifiable data available.
Careful plant monitoring is advisable upon the initial
installation of Grease Guzzler. If the drainage system has
been heavily congested with grease over a long period of
time, the unit could become temporarily overloaded as a
result of the sudden grease influx as pipes are cleared. Also,
segments of grease may be released from the pipe walls.
These segments can collect on bends or other restrictions in
the pipe run and cause a blockage. Pressure pipe cleaning is
recommended on systems that have a heavy grease load.
Conditions vary greatly between sites, and your supplying
WPL distributor will offer appropriate advice upon assessing
the specific application.
Service and maintenance
Grease Guzzler has been engineered for complete reliability.
Absolutely no user maintenance is necessary. In order to keep
kitchen disruption to a minimum, a six-monthly supplier service and
refill programme is all that's required. This will be managed and
undertaken directly by our Service Department, who will provide a

RainSava
The RainSava is the first complete rain water recovery system
designed specifically for the British market
E
ach year we all face the possibility of
water shortages or hose pipe bans.
Yet we continue to waste purified
drinking water for flushing the toilet,
washing our clothes, cleaning our cars
and watering our gardens. We do not
need to waste our expensively purified
drinking water, that is so often in short
supply, on these uses.
The revolutionary new Acorn RainSava
is designed to help overcome this
problem. Natural rainfall that falls on the
roof of your property is filtered and
collected in an underground tank. We
then offer a number of economic options
for distributing the water to the required
locations around the home.
Whilst the RainSava will benefit any home, it
can also be used in many industrial or
commercial situations. Uses can range from
cooling water to supplying water to flush public
toilets in rural locations or even on campsites.
The Acorn
RainSava
Gold System
Apart from the obvious environmental benefits, the increasing
use of water meters will mean that the use of rainwater harvesting
systems, such as these, will provide a saving on your water bill.
Each home is assessed individually to maximise the effectiveness of the
recommended system. We are also working towards the recovery and re-use of
‘grey water’, from sinks, baths, showers and washing machines.
If you have a project that you feel may be suited to the RainSava system, then
please do not hesitate to contact us for a appraisal of your requirements and a
budget quotation.
RainSava Component Options
Collection Filters
Underground Collection Filter
Located in the rainwater pipe run after it goes underground, the
unit contains a stainless steel filter that diverts the rainwater
into the supply pipe to the RainSava underground storage tank.
All excess water and filtered dirt particles continue in the usual
way to the surface water drain.
Vertical Collection Filter
Similar to the underground filter but is located within the vertical
rainwater downpipe before it reaches the ground.
Rainwater Distribution
Pumps
The RainSava ‘Gold’ and ‘Silver’ systems use a submersible
pump situated within the underground tank. The ‘Bronze’
system uses a separate pump, which can be located within the
house or an outbuilding.
Pressure Switch
All of the systems use a pressure switch to control the
operation of the pump.
Floating Filter
The pump takes water from the tank via a floating filter. The
float maintains the position the filter intake just below the
surface of the water for maximum efficiency.
Mains Top-Up
The system also senses the water level within the underground
tank. At times when there is insufficient rain to maintain a
working level, the system compensates by automatically
introducing water from the mains supply into the underground
tank. It is important to note that it only uses enough mains
water to maintain a minimum working level within the tank.
Underground Storage Tanks
Underground storage tanks are available in a range of
sizes, in both horizontal and vertical cylindrical formats.
The inlet and outlet pipework connections can be
located in any position to suit your particular site
conditions.
We also offer a range of above ground storage tanks,
which are ideally suited to industrial applications.

Rainwater is collected from the roof drainage system by the underground Wisy
WFF vortex filter (1). This filters out the debris from the water and diverts about
85% of it into the storage tank. The remaining water goes to soakaway or storm
drain in the usual manner, as does the excess water from the tank. As water
enters the tank it passes through a smoothing inlet (2) which calms the flow of
water and prevents disturbance of the float switch and any sediments.
Water is then supplied on demand by the submersible pump (3) through a floating
suction filter (4) to specific outlets, usually WCs, washing machine and garden tap.
The pump is controlled by a combined pressure switch/flow controller (5), which
turns the pump on and off when required and also gives dry-running protection to
the pump if it should be necessary.
Mains water top-up is provided by a solenoid valve (6) controlled by a float switch
(7). Water is discharged to the tank via a type A air gap tundish (8) compliant with
current water regulations. This gravity-feeds to the tank through 50mm pipe that
then connects to the outlet pipe from the filter.
Water is pumped via pressure hose (9) and 32mm MDPE (10) up to the flow
controller. Pipe and cables are ducted to the house through a 110mm drainage
pipe (11).
An overflow trap (12) provides a water seal against any foul odours from drains.
N.B. – an anti-backflow version is available when connecting to sewer.

TANK CONNECTIONS
Standard uninsulated cisterns
Connections can be made by cutting the tanks in situ or
alternatively a service is available for factory fitting of bosses
and spigots to suit your requirements.
Insulated / Series 30 cisterns
We will alleviate the insulation at all your cistern connection
locations, eliminating the risk of site work which may result in
the insulation and GRP laminate being exposed.
BENEFITS
HEAT & CHEMICAL RESISTANCE
WRc Approved
Maintenance free
Modern design in metric and imperial sizes
Low weight with high mechanical strength

Very competitive prices
POW’s standard products cover many chemical storage
requirements and storage of water up to 55oC, although our
cisterns will stand occasional higher temperatures and are
therefore suitable for feed and expansion. For cisterns other
than cold water storage please advise all chemical elements
including trace elements, their percentage and the minimum
and maximum working temperature.
CONSTRUCTION
All POW cisterns are moulded in one piece and laminated by
hand in superior quality Water Research Council approved
polyester resin / glass fibre. All but the domestic range have
a steel frame encased within the laminate which gives
maximum support and minimum deflection to the tank walls.

BYLAW 30 – At a Glance
Cisterns Storing Water for Domestic Purposes
(1)
Every storage cistern for water supplied for
domestic purposes, shall (a) be installed in a place or position which will
prevent the entry into that cistern of surface or
groundwater, foul water, or wa te r wh ic h is
otherwise unfit for human consumption; and
(b) comply with paragraph (2)
(2)
Every cistern of a kind mentioned in paragraph (1)
shall (a) insulated against heat and frost; and
(b) when it is of a material which will, or is likely to
contaminate stored water, be lined or coated with
an impermeable material designed to prevent such
contamination; and
(c) have a rigid, close fitting and securely fixed
cover which (i) is not airtight
(ii) excludes light and insects from the
cistern
(iii) is made of a material or materials which
do not shatter or fragment when broken
and which will not contaminate any water
which condenses on its underside
(iv) in the case of a cistern storing more than
1,000 litres of water, is constructed so
that the cistern may be inspected and
cleansed without having to be wholly
uncovered
(v) is made to fit closely around any vent o r
expansion pipe installed to convey water
into the cistern, and
(d) be proved with warning and overflow
pipes, as appropriate, which are so constructed
and arranged as to exclude insects.
For those locations with restricted access, we can offer a twopiece split-design tank, which incorporates a central joint,
suitable for assembly on site by others.
FABRICATED RANGE
This range is especially designed for difficult locations, narrow
access and specific sizes.
We can supply any length, width or height to suit your
requirements.
DRIP TRAYS
GRP Drip Trays are available in standard sizes for Domestic, ‘S’,
‘D’ and ‘SD’ ranges.
GRP Fabricated Trays to suit any length or width requirement are
also available.
T K Services
Sectional
Storage Tanks
POW enjoys a reputation of quality service and economy
achieved by performance and product design.
Their sectional cisterns are available in metric and imperial
sized panels offering a vast range of versatile components
to suit your installation needs.
Coloured light grey and laminated by hand utilising the
highest quality Water Research Council approved polyester
resin/glass fibre.
Engineered and manufactured under strict quality control,
these panels require no special protection and
are maintenance free.
APPLICATIONS
GRP is non toxic and has
established itself as the most
suitable material for water
cistern construction. POW’s
Cisterns are designed
primarily for the storage of
potable water and may be
used for internal or external
applications. Many other water and liquid applications are
satisfactory but our advice on suitability should be sought.
INSULATION
Insulation as a core material, within the structure of each
panel to 0.65 W/M20oC, is available for metric cisterns up to
3m high and 8’ high on imperial designs.
Ozone friendly – CFC free insulation is used as standard.
CISTERN ERECTION
We recommend the use of our own experienced installation
teams to erect cisterns in mainland United Kingdom.
Customers, with the use of simple hand tools, can
erect smaller sectional cisterns.
CONNECTIONS
A full service of tank connections,
spigots and composite unions –
factory or site fitted – are available.
PARTITIONS
Partitions may be fitted to cisterns at
full or half panel joints, and are
designed to allow either compartment to be
empty whilst the others are in service.
LIDS
Heavy duty covers are provided with the use of standard
panels. A manway access hatch and filtered air vent are
supplied for each cistern compartment.
BALLVALVE BOXES
Valve boxes may be formed from standard panels. A onepiece ballvalve box is available having internal dimensions
of 800 x 400 x 400 high. Overflows must be fitted within
tank compartment, to ensure the tank is not pressurised.
FIXINGS
Stainless steel nuts, bolts and washers are used
throughout and are an integral part of the maintenance free
concept.
LADDERS
GRP ladders are available for both internal and external
applications. Alternatives in stainless steel or galvanised
steel available upon request.
BRACING
Larger cisterns are braced with stainless steel internal tie
rods, eliminating external corsetry.
TOTALLY INTERNALLY FLANGED
Standard sectional cisterns require clearances beyond the
external dimensions of the cistern. If confined areas exist
and the normal clearance of 500mm cannot be achieved,
choose a totally internally flanged cistern. These systems
are assembled from within, allowing cisterns to be built
right up against existing plantroom walls, columns, even
existing pieces of equipment. POW’s specially designed
system with its complex full corners and ‘L’ panels is
available in metric or imperial sizes with all panel size
variations. You can choose either insulated or uninsulated
options.
TANK CONNECTIONS
A full service of flanged tank connections, spigots and
composite unions – factory or site fitted – are available for
ease of installation.
TANK SIZES
POW’s internally flanged sectional tanks are available in
length and width permutations of 500mm (for metric tanks)
and 2’0” (for imperial tanks). The maximum heights
available for metric tanks are 2,500mm (uninsulated) and
3,000mm (insulated), and for imperial tanks are
8’0” (uninsulated) and 10’0” (insulated).
We also supply a range of equilibrium and delayed action
float valves to suit most site applications.
EXTERNALLY FLANGED CISTERNS
A wide range of options are available to enable an
externally flanged sectional tank to be produced to suit your
requirements. POW’s range of metric cisterns can
incorporate panels in 500mm permutations for any length
and width, up to a maximum of 3,000mm in height, and
their imperial range in increments of 2’0” up to a maximum
height of 12’0” (for uninsulated standard panels) and
8’0” (for pre-insulated panels).
To accommodate the requirements of a type A air gap
arrangement, we can supply weir slots at high level on
the tank (with and without stainless steel mesh and
frame), to suit the specification and bore of the inlet.
Raised ballvalve boxes can also be utilised within this
design.
Access – Externally flanged tanks require a minimum of
500mm clearance all around the tank for access and
maintenance purposes. Where access is restricted and
external flanges are unsuitable, we recommend a Totally
Internally Flanged Cistern.
Flanges – Both internally and externally flanged base
panels are available with externally flanged sides, to suit all
methods of base support and available access. Full span
self-draining base and sump panels are also available
within the range of external bases, to allow complete
drainage of the tank contents.
Up to 4” (100mm) may be fitted in standard panels. Fittings
above 4” may require special panels to be manufactured to
your needs – check with our technical staff when
discussing your connection requirements.
uPVC flanges and spigots are available in either Table D/E
or NP10/16 – please specify the table drilling you require.
TYPE A AIR GAPS
DRIP TRAYS
We are able to supply a full range of GRP drip trays for
POW’s sectional cisterns. These are designed to be
sited beneath internally flanged bases.
INSULATED SECTIONAL CISTERNS
POW’s specially designed and proven system is your
answer for fully encapsulated total insulation.
