If you’re installing a new drain and need to connect it to a public sewer, you’ll likely come across something called a Section 106 application.
For many property owners, this is unfamiliar territory — but it’s an essential part of the process when connecting to the public drainage system in the UK.
What Is a Section 106 Application?
A Section 106 drainage application is a formal request to connect a private drain to a public sewer.
It is required under the Water Industry Act 1991 and must be approved by your local water authority before any connection work can take place.
This ensures that new connections are carried out safely and do not affect the wider sewer network.
When Do You Need One?
You will need a Section 106 application if your new drain is connecting to a public sewer.
This typically applies to:
- New builds
- Property extensions
- Replacement drainage systems
- Commercial developments
If your drainage system only connects to private drains within your property, a Section 106 application may not be required.
What Information Is Required?
As part of the application, you will need to provide details about your drainage system.
This usually includes:
- Plans showing the layout of the drain
- Location of the connection point
- Pipe sizes and materials
- Method of connection
Accurate information is essential for approval.
The Approval Process
Once submitted, the water authority will review your application.
They will assess whether the connection is suitable and whether it meets their requirements. If approved, you will be given permission to carry out the work.
This process can take time, so it’s important to factor it into your project timeline.
Inspections and Compliance
In many cases, the connection work will need to be inspected.
This ensures that the installation is carried out in line with the approved plans and meets all required standards.
Failure to comply can result in the connection being rejected.
What Happens If You Don’t Apply?
Connecting to a public sewer without approval is not permitted.
If you proceed without a Section 106 application, you may face:
- Enforcement action
- Fines
- Having to remove or redo the connection
Ensuring approval is in place avoids these risks.
Who Handles the Application?
While the property owner is responsible for ensuring the application is submitted, a professional drainage company will often manage the process.
This includes preparing the required plans, submitting the application, and liaising with the water authority.

The Section 106 process can be complex, especially if you’re unfamiliar with it.
Working with an experienced company ensures everything is handled correctly and avoids delays.
Companies like RR First Drainage Care & Repair, with over 1,000 five-star reviews across Google and Checkatrade, regularly manage these applications as part of their service.
