Drainage Build Over Agreements in
Caernarfon
Extending over or near a public sewer in Caernarfon needs approval from Dwr Cymru Welsh Water, entirely separate from planning permission itself. Getting the structural detail right the first time keeps this fast, without cutting corners.
Get StartedUnderstanding Caernarfon’s Build Over Requirements
Getting Dwr Cymru Welsh Water’s approval for a Caernarfon 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 Caernarfon 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.
Every Caernarfon 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.
