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.
