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