Drainage Build Over Agreements in
Corsham (Wiltshire)
Extending over or near a public sewer in Corsham 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 Corsham’s Build Over Requirements
Thames Water treats build over approval for Corsham 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 Corsham planning application.
Whether a CCTV inspection’s needed for a Corsham 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.
