Local List Glossary

When is this required?

• development proposals that would result in the disposal of foul sewage, effluent or trade waste not through a mains connection to a public sewer.

What information is required?

A non-mains drainage assessment should be used to establish whether non-mains drainage, either a new system or connection to an existing system, would be acceptable. The Environment Agency requires applicants to provide evidence that a connection to the public sewer is not feasible.

The assessment should include: the method of storage, treatment and disposal, an assessment of site suitability and a demonstration as to why the development cannot connect to the public mains sewer. 

The assessment should be provided through the completion of the Environment Agency's Foul Drainage Assessment form.
