Every sewered property has a defined connection point, recorded on the authority's drainage plans with its position and invert depth. Upstream of that point, drains are private assets the owner maintains; downstream is the utility's network.
Knowing where the connection point sits is essential when a blockage is being diagnosed — it determines who is responsible for the fix.
Defines where private drainage ends and the public network begins.
Usually near the property boundary, at the depth recorded on drainage plans.
A CCTV drain inspection is the standard way to confirm whether this is what's happening in your pipes: the camera shows the condition on screen, a locator pinpoints the exact position and depth, and you get a recorded report before any repair decisions are made.
A CCTV drain inspection shows exactly what's happening inside your pipes — no guesswork.
