Restaurant Owner
Property Type:
Commercial Restaurant
Location:
Brixton, London
The Assessment
Our team carried out a full inspection, which included:
- Clearing the blocked interceptor
- Conducting CCTV surveys of the drainage pipes & connections
- CAT scanning the area to identify existing underground services
- Producing a detailed report based on our findings

The Solution
Based on our assessment, we determined that removing the interceptor and installing a
correctly graded, direct drainage run would provide a more reliable, maintainable, and
compliant long-term solution.
Key Steps
1. Breaking out and removing the existing interceptor.
2. Cutting the existing pipework and installing a Fernco band seal.
3. Adjusting pipe falls and modifying pipework to achieve correct drainage gradients.
4. Reinstating the area and clearing the site upon completion.
5. Completing all work within a strict 3-hour window to align with the restaurant's opening times.
The Result
The newly configured drainage system was fully tested and commissioned to confirm
reliable operation and optimal performance.
Removing the interceptor eliminated the recurring blockages and unpleasant odours. The system now drains efficiently, with no standing sewage water remaining in the
chamber, providing a cleaner, more dependable solution for the restaurant.
