Drainage Build Over Agreements in
Cwmbran
A Cwmbran 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 StartedThe Real Process Explained For Cwmbran
Getting Dwr Cymru Welsh Water’s approval for a Cwmbran build over agreement means submitting real structural detail, not just a general description, showing exactly how the foundation design accounts for the sewer’s presence.
For some Cwmbran projects a CCTV survey forms part of that submission, for others it doesn’t, Dwr Cymru Welsh Water’s requirement depends on the individual site. We’re upfront about which applies before any work starts.
