Drainage Build Over Agreements in
Lymington (Hampshire)
A Lymington extension crossing a public sewer route needs sign-off from Southern Water before work starts. It’s a real, separate approval, and getting the detail right the first time is what keeps the whole thing fast.
Get StartedUnderstanding Lymington’s Build Over Requirements
Southern Water treats build over approval for Lymington 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 Lymington planning application.
Whether a CCTV inspection’s needed for a Lymington 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.
We keep Lymington clients clear on the distinction, Southern Water’s build over approval and planning permission are two separate, real requirements, and missing either causes genuine problems later.
