Sewer connection

If you're looking to make a new sewer connection, you will need Wessex Water's consent.

If you are connecting a pumped rising main, we will need extra details to check the potential septicity impact on our system.

A pumped rising main needs a break chamber to slow the flow before the connection point to our public sewer.

We require all contractors and their employees to obtain a permit card prior to working in a confined space on our assets. Most of our manholes are classed as confined spaces, and we have a restricted operations policy which applies to our staff and contractors.

⚠ Important information

Where mechanical Pipe Stoppers are being used for manhole remedial works, air testing, or temporary isolation of sewers, a secondary restraint system must be applied between the stopper and a fixed point in the manhole.

A Check system must be employed in order that the Stoppers are removed on completion of any works.
