Drainage Build Over Agreements in
Thames Ditton
A Thames Ditton extension crossing a public sewer route needs sign-off from Thames Water before work starts. It’s a real, separate approval, and getting the detail right the first time is what keeps the whole thing fast.
Get StartedUnderstanding Thames Ditton’s Build Over Requirements
Getting Thames Water’s approval for a Thames Ditton 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 Thames Ditton 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.
Every Thames Ditton enquiry gets checked against both requirements honestly, planning permission and Thames Water’s build over agreement, since conflating the two causes real delay.
