Blocked drains in Greenwich
For a blocked drain in Greenwich, identify whether the property is a house or unit, which fixtures or lots are affected and who controls the service access. A similar symptom can involve a private branch, shared line, private stormwater pipe or public network asset.
Blocked drain decisions in Greenwich
Greenwich had 2,128 occupied private dwellings in the 2021 Census. Separate houses accounted for 50.6% and flats or apartments for 43.8%; 909 occupied flats or apartments were in purpose-built blocks. The mix makes both private-yard and managed-building pathways credible without describing a specific address.
Lane Cove Council says owners maintain private stormwater drains and property-drainage pipes, even where part of that private system crosses council land. Sydney Water handles confirmed network wastewater faults, while strata responsibility depends on the pipe and lots served.
- House-drain clearing through a confirmed outdoor access point
- Unit and common-line triage with building or strata management
- CCTV where repeat symptoms or responsibility require a fault position
- Stormwater checks that distinguish private property drainage from council assets
The next step depends on the evidence
- 01 · Clear
Restore safe flow
Clear the obstruction using a method suited to the accessible line and stop the immediate backup or overflow.
- 02 · Inspect
Confirm the cause
Use CCTV when the blockage repeats, the condition is uncertain or the fault position must be documented.
- 03 · Repair
Fix a proven defect
Recommend repair or relining only when the inspection, condition and blockage history support it.

Blocked drain FAQs for Greenwich
Is a Greenwich unit blockage automatically common property?
No. The pipe and lots it serves determine responsibility. A branch serving one lot may belong to that owner, while shared drainage may be common property. Confirm the affected fixtures and fault position before invasive work.
Does Lane Cove Council maintain private stormwater pipes?
Council’s guidance says the owner maintains private stormwater drains and pipes on private property, including property-drainage pipes on council land. Council maintains its own identified public stormwater infrastructure.
