Drainage Build Over Agreements in
St Albans
Extending over or near a public sewer in St Albans 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 St Albans’s Build Over Requirements
Thames Water treats build over approval for St Albans 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 St Albans planning application.
Whether a CCTV inspection’s needed for a St Albans 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.
This approval runs alongside your St Albans planning permission, not instead of it, both are genuinely needed for a project that involves building near a public sewer.
