Drainage Build Over Agreements in
Lisburn
NI Water has to approve any Lisburn build that goes over or close to a public sewer, a genuine requirement that sits alongside, not instead of, planning permission. We handle the structural and design detail properly, and move quickly.
Get StartedWhat NI Water Actually Needs To See For Lisburn
Getting NI Water’s approval for a Lisburn 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 Lisburn 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.
This approval runs alongside your Lisburn planning permission, not instead of it, both are genuinely needed for a project that involves building near a public sewer.
