Will Sydney Water inspect my property in the Shire?

Only if it's directly affected by the Wastewater Fix work. Sydney Water sends a letterbox notice to those owners and residents, and contacts owners in advance if it needs to come onto the property.

Where does Sydney Water's sewer pipe start?

At the junction on its main. Your private pipes, including the point of connection, belong to you, even where they run past your boundary.

Plumbers across Sutherland Shire: sewer checks and hot water

Plumbers across Sutherland Shire From Grays Point to Cronulla.

The Shire is one council area, Sutherland Shire Council, with Sydney Water running the water and sewer throughout. Most homes are owner-occupied, so the repair is usually yours to arrange. Wherever you are in the Shire, we match your job with a licence-checked plumber who specialises in that kind of work.

Across the Shire

Owners more than renters

At the 2021 Census, 36.4% of the Shire's 83,292 occupied homes were owned outright and 38.8% owned with a mortgage, both above the NSW figures of 31.5% and 32.5%. 22.3% were rented.

Houses, units and townhouses

Across the council area, 60.8% were separate houses, 24.8% flats or apartments and 13.9% semis, terraces or townhouses.

Seven suburbs on Sydney Water's list

A Wastewater Fix update of 30 September 2026 names Grays Point, Gymea, Gymea Bay, Kirrawee, Miranda, Sylvania and Yowie Bay for work over the following 12 months. All seven are in Sutherland Shire.

Sydney Water's 2026 to 2027 work

Wastewater Fix looks for places where rainwater gets into the sewer and overloads it. Owners and residents directly affected get a letterbox notice, and the crews' checks include the private stormwater and wastewater pipes that connect to Sydney Water's system. Your water and sewer keep working during an inspection.

If a fault turns up on your land, it's a private repair. Typical ones are a downpipe running into the sewer or its overflow relief gully, a gully that's damaged or sits too low, and cracked sewer pipes that let groundwater in. A drainage plumber can reconnect the downpipe to the stormwater system, raise or replace the gully, or reline the pipe.

Replacing a hot water system in the Shire

If you own your home, replacing the hot water system is your decision to make. In NSW a plumber needs no Notice of Work to replace an existing hot water system, but it is still licensed work and ends with a Certificate of Compliance.

Building Commission NSW requires a tempering device on every replacement heater, like-for-like included, so the water at showers, baths, basins and bidets stays at or below 50°C. Make sure it's in the quote. Compare options on our Sydney hot water replacement page.

Your suburb

We have pages for Cronulla, Miranda, Caringbah, Gymea, Engadine and Menai. We couldn't read Sutherland Shire Council's website when we wrote this, so ask Council directly about its stormwater, tree and flood rules for your property.

In a unit or townhouse, NSW strata rules usually make the owners corporation responsible for pipes in boundary walls and under the floor, and the lot owner responsible for fixtures inside. Your strata plan and by-laws settle it.

What we would do

If you live in one of the seven suburbs on Sydney Water's list, check your downpipes now. Each should run to the stormwater system, never into the sewer or the gully trap near the outside tap. Fixing one before an inspection is simpler than after. For a hot water swap, ask the plumber to confirm the tempering valve and the Certificate of Compliance in writing.
