Drainage Build Over Agreements in
Didcot
Thames Water has to approve any Didcot build that goes over or close to a public sewer, a genuine requirement that sits alongside, not instead of, planning permission. We handle the structural and design detail properly, and move quickly.
Get StartedUnderstanding Didcot’s Build Over Requirements
Getting Thames Water’s approval for a Didcot 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 Didcot 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 Didcot enquiry gets checked against both requirements honestly, planning permission and Thames Water’s build over agreement, since conflating the two causes real delay.

How We Help in Didcot
For Didcot projects, we establish the real picture first, exactly where the sewer runs, what’s being proposed, and what Thames Water’s specific requirements are for a site like this.
Once that’s clear, the submission gets built around what Thames Water will actually assess, with a CCTV survey arranged only where it’s genuinely called for.
Given how much attention to detail Thames Water expects for a Didcot build over approval, we stay engaged throughout, right up to a decision.
Getting Didcot Build Over Approval Right First Time
Every Didcot submission to Thames Water gets checked properly before it goes in, since a poorly prepared application slows down the fast turnaround we’re aiming for.
Being honest about whether a Didcot project needs a CCTV survey, rather than assuming either way, keeps both cost and timeline realistic.
Every Didcot enquiry gets handled with the attention to detail Thames Water expects, not rushed just to hit a fast turnaround.
