Drainage Build Over Agreements in
Marlow (Buckinghamshire)
A Marlow extension crossing a public sewer route needs sign-off from Thames 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 StartedThe Real Process Explained For Marlow
Where a Marlow project involves building over or within close proximity to a public sewer, Thames Water needs to formally approve it, a genuinely separate process from planning permission, running alongside it rather than replacing it.
A CCTV survey of the existing sewer is sometimes required as part of this in Marlow, though not always, it depends on how well documented the sewer’s exact route and condition already are. We arrange one where it’s genuinely needed, not as a blanket extra.
This approval runs alongside your Marlow planning permission, not instead of it, both are genuinely needed for a project that involves building near a public sewer.
