Building and Developing

New Connection
New site developments
If you're building multiple domestic or commercial properties on a site that will have a new road/access you'll probably need a new water main. You can choose either STW or a WIRS accredited Self Lay Provider (SLP) to lay the new main and/or service connections. Proposed sewers into the site can be offered to us for adoption so we become responsible for them.

Sewer adoption - New site

Step 1: Before you apply

If you are only building a small number of properties that are close to an existing public sewer and the sewer does not need adopting you can apply for a standard sewer connection.

There are some key things you need to know before you’re ready to apply for a new connection. Once you have considered all of these you are all set to send us your application.

Step 2: Apply

How do I apply?

You’ll need to submit the following:

  • A Water and Sewer connections application form
  • A location plan –showing the site boundary in relation to the existing houses/roads and the proposed route of the new sewer connections, if you are connecting to a transferred sewer please indicate the position of the sewer you have located
  • If it's a direct connection – your contractors details
  • If it's a surface water connection – evidence why a soakaway cannot be used
  • The correct application charge, which is dependant on the type of connection                       
Step 3: Approval

What does this include?

We will assess your connection requirements and check our existing network has capacity for the proposed connections. If there are any restrictions placed on surface water flows we will confirm these with you.If we are happy with your proposals we will issue a approval letter for each sewer connection within 21 days of your request.

It will confirm the connection details and the details of the sewer you are connecting to. This may be required by your local building control officer.

 

Step 4: Connection

Who is responsible for carrying out the connection?

We will assess your connection requirements and check our existing network has capacity for the proposed connections. If there are any restrictions placed on surface water flows we will confirm these with you.If we're happy with your proposals we will issue a approval letter for each sewer connection within 21 days of your request. It will confirm the connection details and the details of the sewer you are connecting to. This may be required by your local building control officer.

 

Step 5: Inspect

How do I get the connection inspected?

Once you've received your approval letter you'll need to inform us when the connection is being made allowing 48 hrs notice. If it is a direct sewer connection we will aim to attend site on the day of connection to inspect the work. If the work passes the inspection we will sign it off.If the work does not meet the standard we will tell you on site what remedial work is required. Once this is complete please contact us and we will arrange a new inspection.If it is an indirect connection we will not inspect the connection this will be done by your local building inspector, although it is helpful for us to know when they have been made.

 

Step 6: Adoption

How do we complete the process?

Once the work is signed off by us, we'll issue you with final paperwork confirming who is responsible for the sewer. If the lateral drain leaves the property boundary and enters into public highway we will issue a vesting declaration to show we have taken responsibility from the public sewer back to the demarcation chamber (constructed within 1 meter of the site boundary). If all of the connection work is within the property boundary the sewer will remain the responsibility of the property owner but we will issue a letter to confirm we approved and inspected the connection.

We’ll update our records and billing information for the property. It's important we complete the process to ensure there are no issues if you sell your property and the property shows up correctly on any searches your solicitor will carry out.If you require more detailed information on our process - please read our guidance documents.
