Drainage Build Over Agreements in
Rickmansworth
A Rickmansworth 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 Rickmansworth’s Build Over Requirements
Thames Water treats build over approval for Rickmansworth as a genuine technical review, focused on foundation design and how the proposed structure interacts with the sewer beneath or beside it. This sits entirely separately from your Rickmansworth planning application.
Whether a CCTV inspection’s needed for a Rickmansworth project depends on the specifics, sometimes the sewer’s route and condition are already well established, sometimes Thames Water wants it confirmed first. We arrange it honestly, only where it’s actually required.
Every Rickmansworth enquiry gets checked against both requirements honestly, planning permission and Thames Water’s build over agreement, since conflating the two causes real delay.
