Drainage Build Over Agreements in
Swansea
A Swansea extension crossing a public sewer route needs sign-off from Dwr Cymru Welsh 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 Swansea’s Build Over Requirements
Where a Swansea project involves building over or within close proximity to a public sewer, Dwr Cymru Welsh 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 Swansea, 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.
We keep Swansea clients clear on the distinction, Dwr Cymru Welsh Water’s build over approval and planning permission are two separate, real requirements, and missing either causes genuine problems later.
