Clean water

Apply and pay for our clean water services, including new mains or service connections, using water for building work, disconnecting existing supplies, and diverting or abandoning pipes.

Wastewater

Apply and pay for our wastewater services, including adopting an existing or new sewer, getting approval for a connection, building over or near to a sewer, and diverting a sewer or requesting a new one to be built.

Using self-lay providers

Independent self-lay providers could offer cost-effective terms, fit in better with your construction programme and may also be able to install multiple utilities.

Using NAVs

You can ask a ‘New Appointment and Variation’ (NAV) to serve your development in a defined area known as an inset.
