Drainage Build Over Agreements in
Corwen
Dwr Cymru Welsh Water has to approve any Corwen build that goes over or close to a public sewer, a genuine requirement that sits alongside, not instead of, planning permission. We handle the structural and design detail properly, and move quickly.
Get StartedWhat Dwr Cymru Welsh Water Actually Needs To See For Corwen
Where a Corwen 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 Corwen, 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.
Every Corwen enquiry gets checked against both requirements honestly, planning permission and Dwr Cymru Welsh Water’s build over agreement, since conflating the two causes real delay.
