Check if permission is needed from the local planning authority and the Environment Agency, e.g. if a listed building or scheduled monument will be affected. If so, send their advice and a copy of any consents with the application.
Applicants must also send dated photographs of the existing site with their application. With permission from Natural England, advice and consent can be received up until 29 May 2015; applicants can discuss this with their local CSF officer.
On the land
Successful applicants must make sure the work meets:
- relevant British Standards - check the most up-to-date standards; and
- control of water pollution regulations if the work is designed to transfer slurry or silage effluent.
Lay the pipes
Successful applicants will need to:
- excavate trenches that are at least the width of the pipe’s outside diameter plus 300mm;
- lay pipes on clay or sand that’s at least 100mm thick;
avoid settlement of solids or semi-solid material in dirty water drains and lay pipes to a fall of:
- no less than 1 in 60 for 100mm internal diameter pipes
- no less than 1 in 100 for 150mm internal diameter pipes
- make sure that manholes are no more than 90m apart in straight lines;
- only use uPVC pipes with sealed joints, and join them correctly (follow the manufacturer’s instructions);
backfill once the pipe has been laid to at least:
- 600mm in areas without traffic
- 900mm in areas with traffic; and
- use compacted excavated material such as smooth stone, clay or sandy soil for backfill and remove any surplus.
If it’s not possible to backfill to 600mm (900mm in areas with traffic) then the pipes must be wrapped in plastic sheeting and encased in at least 150mm of concrete.
Successful applicants will need to keep:
- dated photographs to show that the item requirements have been met, (take them before, during and after, then submit these with your claim and show them on request);
