Sewerage connection - Commercial property

Step 1: Before you apply

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 connections application form.
  • A location plan – showing the site boundary in relation to the existing properties/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 is a direct connection – your contractor's details including site specific method statement and risk assessment for the works.
  • If it is a surface water connection – evidence why soakaways cannot be used.
  • An approval fee per connection – Depending on the number of and type of connection there is a different fee associated:
    • A direct connection to a public sewer in public highway is £455.67.
    • A direct connection to public sewer in private land is £224.98.
    • An indirect connection (to a private drain which then outfalls to a public sewer) is £96.41 (For more info our charges see our FAQs or our charges booklet).

Please note, these are the charges for Seven Trent to approve the connection, the cost of the actual work to complete the connection will vary and will be determined by the contractor you use.

You can apply on the same application form for multiple connections to our existing sewers.

For more info our charges see our FAQs or our charges booklet.

When you're ready to apply download our application and read our sewer connection guidance notes.           

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 an 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's responsible for carrying out the connection? 

You’re responsible for carrying out the sewer connection/s usually through employing a contractor. Once you have received your approval letter you can then go ahead and instruct the work to be carried out.  

For more information about the technical requirements for laying your sewer see our sewer connection guidance notes.

Step 5: Inspection

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. If it is a direct sewer connection please give us at least 48 hrs notice as 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 is 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.
