Drainage Build Over Agreements in
Portishead
Extending over or near a public sewer in Portishead needs approval from Wessex Water, entirely separate from planning permission itself. Getting the structural detail right the first time keeps this fast, without cutting corners.
Get StartedWhat Wessex Water Actually Needs To See For Portishead
Getting Wessex Water’s approval for a Portishead 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 Portishead projects a CCTV survey forms part of that submission, for others it doesn’t, Wessex Water’s requirement depends on the individual site. We’re upfront about which applies before any work starts.
We keep Portishead clients clear on the distinction, Wessex Water’s build over approval and planning permission are two separate, real requirements, and missing either causes genuine problems later.
