Using a self-lay provider

Self-lay providers could offer a cost and time effective solution for your construction programme.

Connecting to a sewer

Find out timescales, charges and other information about connecting your development to our public sewerage system.

Building over or near a sewer

Apply to us if you plan to build over or within three metres of a public sewer.

Adopting a new or existing sewer

Speak to us about adopting a sewer or a pumping station, prior to construction.

Diverting a sewer

If you need to alter or remove a public sewer on your development site, you can apply for a diversion.

Requisitioning a sewer

If your development has no drainage to an existing public sewer because third party land is in the way, we can provide both a foul and surface water sewer to serve the site.
