Drainage Build Over Agreements in
Elstree
Extending over or near a public sewer in Elstree 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 Elstree’s Build Over Requirements
Thames Water treats build over approval for Elstree 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 Elstree planning application.
Whether a CCTV inspection’s needed for a Elstree 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.
We keep Elstree clients clear on the distinction, Thames Water’s build over approval and planning permission are two separate, real requirements, and missing either causes genuine problems later.

How We Help in Elstree
For Elstree 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.
Elstree submissions to Thames Water get followed through properly, with anything they raise addressed directly and promptly.
Getting Elstree Build Over Approval Right First Time
We give Thames Water exactly the structural and design detail they need for a Elstree project, not a generic submission that risks queries and delay.
Being honest about whether a Elstree project needs a CCTV survey, rather than assuming either way, keeps both cost and timeline realistic.
Whatever a Elstree project actually involves, structural detail, design detail, or both, we prepare it properly for Thames Water from the outset.
