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