Drainage Build Over Agreements in
Alton (Hampshire)
Extending over or near a public sewer in Alton needs approval from Southern Water, entirely separate from planning permission itself. Getting the structural detail right the first time keeps this fast, without cutting corners.
Get StartedWhat Southern Water Actually Needs To See For Alton
Southern Water treats build over approval for Alton 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 Alton planning application.
Whether a CCTV inspection’s needed for a Alton project depends on the specifics, sometimes the sewer’s route and condition are already well established, sometimes Southern Water wants it confirmed first. We arrange it honestly, only where it’s actually required.
