When Are Sewer Diversions Needed?

Sewer diversions are often required when existing sewer lines run through areas that are being altered, extended or redeveloped. Moving a sewer line is not simply a case of changing direction — it requires proper design, approval and installation to ensure the system continues to perform safely and effectively:

Property extensions: where an existing sewer line sits beneath a planned extension.
New build development: where underground drainage needs rerouting to suit the site layout.
Landscaping works: where major changes to levels or external layout affect existing sewer routes.
Building over sewers: where diversion is needed to comply with regulations and approvals.
Damaged or poorly positioned lines: where existing sewer runs are no longer practical or reliable.
CCTV-led redesign: where survey findings highlight the need for rerouting work.
Authority compliance: where local regulations require formal diversion design and approval.
Long-term site planning: where a more practical sewer route is needed for future use of the property.

Our team can assess the existing drainage layout, carry out the necessary surveys and complete the diversion works to a high standard, ensuring the new sewer route is safe, fully operational and built for long-term use.
