Auburn at a glance for plumbing
On Sydney Water's work list
A Wastewater Fix update dated 4 December 2025 names Auburn among the suburbs where Sydney Water crews will work over the following 12 months. Owners who are directly affected get a letterbox notice first.
Haslams Creek flood study
Cumberland City Council's study of the Haslams Creek catchment covers Auburn, Lidcombe, Berala, Rookwood and Regents Park. Feedback closed on 12 June 2026 and a draft study is planned for 2026 to 2027.
Houses and units, nearly even
In 2021, 42.0% of Auburn's occupied homes were separate houses and 47.3% were flats or apartments. Almost half, 49.9%, were rented.
Why Sydney Water cares about your gully trap
When it rains, stormwater can find its way into the wastewater system and overload it, sometimes until sewage overflows inside homes. Sydney Water names the usual ways in: downpipes plumbed into the sewer by mistake, cracked or badly sealed private pipes that let groundwater through, and overflow relief gullies that are damaged or sit too low.
The gully is the grated fitting outside, often near a tap, that lets a blocked sewer spill in the yard instead of the house. Rain shouldn't be able to run into it. If yours is cracked, flush with the paving, or has a downpipe draining into it, a drainage plumber can raise or replace it and move the downpipe onto the stormwater line.
Where your pipes end
Cumberland City Council's line is plain: an owner is responsible for the services to their property, sewer and stormwater pipes included, even where they run under public land. That responsibility lasts until the pipe meets a drainage point such as a Sydney Water main, a street gutter or a pit.
Sydney Water says much the same about the sewer. The owner's section includes the point of connection, and only the junction is Sydney Water's. Shared inter-allotment stormwater lines are the business of the owners they serve, not Council.
If the yard floods or the gully overflows after rain
- Check whether any downpipe empties into the gully or a sewer pipe.
- Look for a cracked, sunken or buried gully grate.
- Note whether it overflows only in rain, or also when you run water inside.
- Ask your neighbours whether theirs did the same.

Our advice for Auburn owners
If Sydney Water's notice turns up in your letterbox, there's no need to panic: it says its inspections don't interrupt water or wastewater services. If a fault shows up on your side of the connection, it's yours to fix, so get a licensed drainer to quote and ask for the Certificate of Compliance when the work is done. We can match you with a drainage specialist who does this kind of repair.
