Drainage Build Over Agreements in
Twyford
Extending over or near a public sewer in Twyford needs approval from Thames Water, entirely separate from planning permission itself. Getting the structural detail right the first time keeps this fast, without cutting corners.
Get StartedUnderstanding Twyford’s Build Over Requirements
Getting Thames Water’s approval for a Twyford build over agreement means submitting real structural detail, not just a general description, showing exactly how the foundation design accounts for the sewer’s presence.
For some Twyford projects a CCTV survey forms part of that submission, for others it doesn’t, Thames Water’s requirement depends on the individual site. We’re upfront about which applies before any work starts.
This approval runs alongside your Twyford planning permission, not instead of it, both are genuinely needed for a project that involves building near a public sewer.
