WCSEE LTD T300 SAF TANKS
1. SAFETY
It is extremely important that maintenance procedures in this document are
followed. Any deviation from this could cause serious injury or have a detrimental
effect on its operation.
Health and safety at work act 1974
Section 6a of the act requires manufacturers to advise their customers on safety
and handling precautions to be observed when operating, maintaining and
servicing their products.
The user’s attention should be drawn to the following:
•All sections of this manual should be read before undertaking work on the
equipment.
•Suitably trained personnel must carry out the installation.
•Normal Health and safety precautions must be taken and appropriate
procedures observed to avoid accidents.
•Refer to WCSEE Ltd for further technical advice or product information.
General health and safety
The layout of the WCSEE LTD T300 tanks have been laid out to ensure that
health and safety on site is optimised in line with designer duties specified by the
CDM regulations 2015. It will be safe manner, and agrees with comments from
the principal designer. Lone working in, and around the plant should be
prohibited.
Leptospirosis
The following is extracted from a health warning card issued to WCSEE LTD staff.
It is the client’s responsibility to ensure that the relevant Personal Protective
Equipment (PPE) is available and used.
There are two types of Leptospirosis that effect people in the UK and they are as
follows:
•Weil’s disease, which is a serious infection transmitted to humans by
contact with soil, water or sewage that has become contaminated with
urine from infected rats.
•Hardjo-type Leptospirosis, which is transmitted from cattle to humans.
The typical symptoms for both diseases start with a flu like illness, with a
persistent and severe headache, muscle pains and vomiting. Jaundice generally
appears on the fourth day of the illness.
The bacteria can enter your body through cuts and scratches or through the
lining of the mouth, throat and eyes.

WCSEE- T300 INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Sensible Precautions
After working with contaminated fluid or other materials it is important that hands
and forearms are washed thoroughly with soap and water. If your clothing or
boots become contaminated, then they should also be washed immediately after
use.
Immediate action should be taken, so that any cuts scratches or abrasions are
washed thoroughly with clean water, prior to applying any protective covering
(plaster or bandage).
Do not handle food, drink or smoking material without first washing your hands. If
you display any of the symptoms described after coming in to contact with
sewage; report to your doctor immediately advising them of the circumstances.
Vaccinations
To avoid the possibility of illness it is recommended that all site personnel have
the following vaccinations. WCSEE Ltd also recommends that you that you
consult your doctor for any additional vaccinations that you may require. The
general vaccinations WCSEE use for all personnel are as follows:
•Hepatitis A
•Hepatitis B
•Polio
•Tetanus
•Typhoid/cholera –probably carried out as a child.
2. Warranty
WCSEE Ltd will provide the following warranty to the items listed below:
Note: warranty period will be active from the day, from which the tanks are
positioned on the base slab, or passes on to the customer’s
premises/construction site.
T300 tank enclosures
WCSEE Ltd will provide a 12 month warranty period for the external & internal
structure of the tank.

M&E installation
WCSEE LTD takes no responsibility for improper storage, or bad
installation/maintenance performed by unqualified personnel. This also covers
the overloading of the plates, above that of normal conditions, and any other
accidental cause, or disregard for the information in this document.
Warranty limitations and exemptions
WCSEE Ltd shall not be liable for any labor involved for the removal or
replacement of its equipment or the subsequent transportation, handling or
packaging of any part or parts thereof. In no case will WCSEE Ltd be liable for
loss incurred because of interruption of service or for consequential damages,
labor or expense required to repair defective units, nor shall this constitute a
cause for the cancellation of the contract of purchase and sale. Specifically
exempt from this warranty are limited life of consumable components subject to
normal wear and tear.
Chargeable non warranty work
Service charges will be incurred (including parts and labour), due to the
following:
•Unauthorized alteration.
•Accidental damage, caused by plant or movement on site outside of
WCSEE’s control.
•Improper use.
•Abuse.
•Tampering.
•Failure to follow installation instructions or failure to follow operating and
maintenance procedures.
The above will not be covered by this warranty. All service visits for non-warranty
work are chargeable at the standard engineer day rate plus mobilization. This
warranty gives specific additional benefits. Statutory rights are unaffected.
Note: WCSEE LTD will not uphold the guarantee on the purchased equipment if
the routine maintenance has not been performed and documented.
WCSEE LTD strongly recommends that the installation of the purchased product
is carried out by a qualified and experienced installer. Dependent on the site a
suitably qualified civil engineer may need to be consulted for the construction of
suitable base slab to support the imposed load.

3. Risk assessment
Introduction
This section of the manual is intended as a guide and as such does not cater for
every situation encountered on site. WCSEE assumes that the necessary
permissions have been granted prior to the installation of the plant. It is also the
assumption that working methodology abides by the Health and Safety at work
act and that all civil engineering design is undertaken by a chartered Civil
Engineer.
Please ensure that due consideration is given to the following:
3.1.1 Installation Design Considerations
•Planning permissions & Building Regulations and other regulating or
interested parties.
•Environment Agency consent to discharge.
•The size of the plant relevant to the number and type of people that will be
using it, e.g. domestic, light industrial, etc.
•Costs, legal implications and siting in consideration to shared systems.
•The whereabouts of wells, boreholes and springs used as sources of
potable water; existing non-mains sewerage systems and soakaways; water
courses, ponds and lakes and designated protected areas.
•The whereabouts of other services, pipes, cables and ducting.
•Local ground conditions. Is specialist knowledge of civil engineering
required, catering for specific ground condition requirements?
•The water table at the time of installation - specialist knowledge is required
when installing in an excavation that allows water to enter.
•The water table in winter - Special consideration should be given to
installations that will be subject to high water table pressure or flood
conditions. The treatment plant will need to be installed so that it cannot
“float” out of the ground and provision made for continued discharge of
treated effluent, should the discharge pipework/soakaway be under water.

WCSEE- T300 INSTALLATION, OPERATION AND MAINTENANCE MANUAL
Page 8 of 21
3.1.2 Installation and positioning
•Siting - The plant must be sited within 30m of heavy vehicle access for
draining. The plant should, where possible, be sited above the high-water
table mark and above or beyond the flood plain. See items above and
accompanying note. The plant should be sited as far from the habitable
parts of the dwelling as possible. Many local authorities recommend 10m
as a minimum, but easements are possible for smaller sites.
•Electrical supply –If the plant has been equipped with a pumped de-
sludge option, a qualified electrician should only undertake electrical
installation. A safe and reliable power supply is required at all times, as the
pumps are required to de-sludge at intervals 24/7. Adequate means of
power failure indication should be provided. This can be an audible or
visual alarm or by regular manual checks.
Note: Due to the health risks associated with raw sewage, WCSEE recommend
that the SAF treatment plant is not used until the system is complete,
commissioned and is operating in a stable manner.
3.1.3 Maintenance
•The legal responsibility for the plant as far as operation and maintenance
and on-going discharge is concerned.
•Electrical supply: a qualified electrician should undertake the electrical
installation.
A reliable power supply will be required at all times, so an indication of
power failure will be required, which can be audible or visual.
•Any visiting personnel should report to the site office and acquaint
themselves with the specific site health and safety protocol.
•Before carrying out any maintenance or installation on the equipment it
should be electrically isolated, unless a trained electrician is carrying out
specific checks under controlled conditions. When performing works of
this nature, warning signs should be erected to alert others of the works in
progress.
•For all works, risk assessments and method statements will be required to
carry out work on site. These should identify the method of work and the
risks associated.
•Temporary barriers and warning signs should be erected around any open
covers or manholes as appropriate, in particular warning of deep water in
the tanks.
•See section 7 for routine maintenance.

4. Introduction
The process used within the WCSEE SAF has been developed to meet the more
stringent discharge consents now being imposed by the Environment Agency,
particularly with reference to low ammonia levels. The HiPAF can achieve
ammonia standards better than 10mg/l.
The T300 and T3HP (for Hire Use) has been designed for above ground
installation only.
The T300 is equipped with an optional access ladder and handrails, where as the
T3HP does not require any top-level access. This is shown in more detail in the
next pages.
Blowers and controls to provide the air are housed in a separate standalone kiosk
adjacent to the plant. The tank and kiosk are manufactured in GRP for corrosion
resistance and long life.
*As these units are above ground and generally receiving pumped flows, it is
therefore necessary to provide suitable flow control before the effluent is received
by the unit.
The plant should receive Dry Weather Flow as stated in the relevant quotation or
design documentation; ensuring adequate hydraulic retention time for the relevant
biological processes to take place.
WCSEE advises the following for lifting practices for the T300 & T3HP tanks:
Checks:
•Inspect all lifting points and tension if required with a suitable tool.
•The unit must be hoisted empty of all material and fluids.
Test lift the unit to check that the centre of gravity of the unit is in the correct
location (See drawing supplied by WCSEE LTD), and that all of the chains are
taut. It is critical to ensure a balanced lift, but if in doubt don’t lift the tank.
