Hurstville is the administrative centre of Georges River Council and the main town centre of the St George area, with Forest Road, Westfield Hurstville and a skyline of residential towers. Once known as Gannon's Forest, it grew once the railway opened in 1884 and the land around the station was subdivided. The town centre has gone up rather than out: at the 2021 census about six in ten Hurstville homes were flats or apartments and three in ten were separate houses. The neighbours are different again. South Hurstville is about half houses, and Hurstville Grove, running down to Oatley Bay, is almost all houses.

Under most of Hurstville is Ashfield Shale, which weathers to clay that is reactive and often drains poorly. It swells when wet and shrinks when dry, and over the years that movement opens the joints of old clay sewer, which is how roots get in. Toward the Georges River the ground changes to Hawkesbury sandstone, with steep slopes and thin sandy soil, so a broken drain in Hurstville Grove can mean digging through rock. The older streets are older than they look: the O'Brien's Estate heritage conservation area is a 1920s subdivision of Inter-War Californian and late Federation bungalows. Water is the other part of it. Georges River Council's 2016 overland flow flood study covers Hurstville, Mortdale and Peakhurst, and the council says plainly that its drains are built for smaller, frequent storms, so in heavy rain water runs across roads and properties.

Every part of Sydney has its own plumbing character, shaped by the age of the housing, the ground it sits on, and the weather it takes. Here is what we are called out for most often around Hurstville.

Reactive shale clay moves with the seasons, and the pipe buried in it moves too. In houses still on their original clay sewer, joints open up, roots follow, and a section can sag and hold water. The blockage tends to come back after it is cleared, because the cause is the pipe. A camera shows which joint has failed, and relining seals it without digging.

With most Hurstville homes now apartments, many blockages are in a common stack rather than a single unit's pipe. Slow drains across several floors, or water coming up in the lowest apartment, point to the stack. It is common property and needs clearing from the stack itself.

The council's drains are designed for smaller, more frequent storms, so in a downpour they fill and water runs over the ground. A property's own pits, grates and lines then have to cope, and if they are silted or broken the water ends up against the house or in the garage.

In Hurstville Grove and the southern edge of South Hurstville, sandstone is close to the surface and the slopes are steep. Long sewer runs down a sloping block and pipe laid through rock make repairs slower if they have to be dug, which is where relining earns its place.

Houses that have never been re-plumbed can still have a galvanised steel water service, which rusts closed from the inside. Pressure that has dropped slowly over years, rather than suddenly, is the usual sign.

Common Questions

Yes. Our phones are answered 24 hours a day, 7 days a week, and for emergencies we aim to be with you within 60 minutes. We give you an ETA when you call, and there is a $0 call-out fee.

In an older house it is usually the original clay sewer. The shale clay here moves as it wets and dries, joints open, and roots get in. Clearing works for a while; a camera inspection shows whether relining that section will stop it coming back.

Yes. We cover Hurstville and the suburbs around it, including South Hurstville, Hurstville Grove, Kogarah, Penshurst, Beverly Hills and Allawah.

When more than one unit is affected it is usually the shared stack, which is common property. We clear it from the stack and give the strata manager a report of what we found.

Georges River Council's own drains are designed for smaller storms, so in heavy rain they can overflow. What you control is your own drainage: we make sure your pits, grates and stormwater lines are clear, unbroken and big enough to get water away from the house.

It depends on the job. You get a fixed price quoted before we start, and there is a $0 call-out fee.
