Online application forms

Water and/or sewer connection application

Use this form if you are applying for a new water or waste connection.

You will need to apply for a new water or waste connection if you’re working on a new development of five buildings or fewer and you need to:

• connect to an existing water main
• increase the water supply from an existing water main
• connect to an existing sewer
• increase the waste flow of an existing sewer

Water and sewer development enquiry

Use this form to find out if a new development can be supplied with water and waste services.

Submit an enquiry for connections to 5+ residential and commercial properties to receive indicative costs and confirmation of our network capacity to serve your development.

Self-lay point of connection application

Tell us if you or your contractors will self-lay a new connection.

Self-lay providers must be accredited by the Lloyd’s register Water Industry Registration Scheme (WIRS).

We’ll assess water and/or waste service capacity for the proposed development.

New water main requisition

Use this application form if a new water main is needed to supply 5 or more properties on a development site.

A water main can be installed or extended when the existing water network cannot supply the new properties. This may be because of:​

• The number of properties​
• the site layout ​
• the distance from the existing network ​

If you just need a connection to an existing water main, apply for a water connection

Adoption of sewers application

You’ll need to complete a sewer adoption application if you want to enter into an adoption agreement with us.

(Section 104 of the Water Industry Act 1991)

You’ll need to complete a sewer adoption application if you want to enter into an adoption agreement with us before the new sewers are built.

In a Section 104 sewer adoption agreement, the developer builds sewers to a standard agreed to by us. We’ll take ownership of the sewer at a later date, usually after a few years.

Sewer requisition application

You must get agreement from the landowner to lay pipes on their land.

(Section 98 of the Water industry Act 1991)

You must get agreement from the landowner to lay pipes on their land. If you’re unable to reach an agreement with a third-party landowner, we can lay the pipes for you.

Complete a Section 98 sewer requisition application if you want us to lay a sewer on your behalf across third party land where you’ve been unable to reach agreement with the landowner.
