What’s a Build Over Drain Survey — and Do You Need One in Derbyshire?
Planning a home extension, conservatory or garage conversion in Derby or Derbyshire?
You might need a Build Over Drain Survey.
What Is It?
When you build over or within 3 metres of a public sewer, Severn Trent (or your water provider) may require proof that:
The drain is structurally sound
The system can be accessed if needed
A drain survey provides that proof — and helps you avoid planning permission delays.
Who Needs It?
Homeowners planning extensions
Builders needing compliance documents
Architects and property developers
We work with local councils, builders and architects to deliver fast, accurate drain reports across Derby and the Midlands.
