Drainage Build Over Agreements in
Lambourn
Extending over or near a public sewer in Lambourn 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 StartedThe Real Process Explained For Lambourn
Thames Water treats build over approval for Lambourn 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 Lambourn planning application.
Whether a CCTV inspection’s needed for a Lambourn 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.
Every Lambourn enquiry gets checked against both requirements honestly, planning permission and Thames Water’s build over agreement, since conflating the two causes real delay.
