The Kensington Road Black Spot Project is wrapping up early May — $1.3 million of drainage, kerb, and median work at the Kensington Road, George Street, and Giles Street intersection. That's been live since early March, and any property on those connecting streets has had ground disturbance within spitting distance of their service connections. Add the 14mm on the 2nd and 15mm on the 4th this month, and you've got saturated clay shifting around pipes that were already under stress. Toorak Gardens runs on 1920s–30s terracotta and galvanised — the kind of infrastructure that doesn't forgive movement. Council also just adopted the Precinct Plan covering Toorak Gardens, which flags future traffic and streetscape treatments across the suburb. If your drains have slowed down or you're seeing damp patches after the rain, ring us — a plumber we dispatch knows exactly what's under these streets.
City of Burnside notes
“Kensington Road Black Spot Project at intersection of Kensington Road, George Street, and Giles Street — $1.3 million drainage, kerb, footpath, and median upgrades running early March to early May 2026”
City of Burnside
Ground disturbance from drainage works on reactive clay soils puts stress on nearby terracotta sewer connections — properties on Giles Street and George Street should watch for new slow drains or damp patches.
“Council adopted Precinct Plan for Dulwich, Rose Park, Toorak Gardens, Frewville, Glenunga and Eastwood — 28 proposed treatments across streetscape, traffic management and active transport (Resolution C32026/14116)”
City of Burnside
Future streetscape and traffic treatments flagged for Toorak Gardens mean more ground disturbance coming — older properties on affected streets will see their ageing infrastructure tested.
“Burnside War Memorial Hospital expansion approved — $65 million, three-storey health precinct with basement parking at 120 & 126 Kensington Road and 2 Moore Street”
City of Burnside
Major excavation and new sewer/water connections for a development this size will increase load on local mains — nearby residential properties may see pressure fluctuations during construction.

Toorak Gardens profile
City of Burnside covers eastern Adelaide from the inner suburbs to the Mount Lofty foothills — pre-war sandstone and Federation homes in the older streets, mid-century brick veneer across the main residential areas, and modern infill on larger blocks. Housing stock from the 1920s through 1970s means original galvanised iron supply lines, terracotta sewer pipes, and ageing copper hot water runs are standard. Mature tree canopy across the council area is the primary driver of root intrusion — established gums, figs, and plane trees have had 50-70 years to find every cracked joint in clay and terracotta sewer lines. Foothills terrain creates faster stormwater runoff and puts pressure on ageing pit infrastructure during heavy rain. The council's current capital works program includes traffic treatments and streetscape upgrades that disturb road reserves and expose service connections.
Giles Street and Alexandra Avenue are the streets that light up after rain — mature tree canopies, 1920s–30s housing stock, and terracotta sewer lines that have been taking root intrusion for decades. The properties closer to Kensington Road tend to be the worst because they're on the original subdivision infrastructure that's never been upgraded. Watson Avenue and the streets feeding into Portrush Road have more 1970s brick veneer mixed in, which means copper supply lines and different failure modes — burst pipes in winter rather than root blockages. The split between pre-war and post-war housing stock here is sharp, and it dictates what breaks.
When calls come in: Toorak Gardens calls tend to come through in the evening — owner-occupiers who notice something wrong after work and want it sorted before morning. Weekend mornings are also common when people have time to investigate that slow drain they've been ignoring.

Toorak Gardens Plumber FAQ
The works at Kensington Road, George Street, and Giles Street involve drainage and kerb upgrades running through to early May 2026. Ground disturbance from heavy machinery can shift reactive clay soils, which puts stress on older terracotta and earthenware pipe joints nearby. If you're within a few hundred metres of the intersection and notice new slow drains, gurgling, or damp patches in your yard, it's worth getting a camera inspection to check for cracked joints or displaced connections before a partial blockage becomes a full collapse.
Slow drains after rain in Toorak Gardens usually mean one of two things: either your stormwater system is overwhelmed and backing up, or tree roots have partially blocked your sewer line and the extra groundwater is exposing the restriction. If it clears within a day, it's likely stormwater capacity. If it persists or you notice gurgling from other fixtures, that's a sewer issue — roots or a collapsed section. A plumber we dispatch can run a CCTV camera through to tell you exactly what's happening and where.
Galvanised steel pipes corrode from the inside out, so you won't see rust on the outside until it's too late. Early signs include reduced water pressure at taps furthest from the meter, brown or orange-tinged water when you first turn on a tap in the morning, and pinhole leaks that show up as damp patches on walls or ceilings. In Toorak Gardens' pre-1960s homes, these pipes are often 60–80 years old and well past their design life. If you're seeing any of these signs, get a pressure test and visual inspection before a pinhole becomes a burst.
A 1930s bungalow in Toorak Gardens typically has terracotta sewer pipes, galvanised water supply lines, and possibly original cast iron stacks if it's two-storey. The sewer lines are the first to go — root intrusion at the joints is almost guaranteed after 90 years. Galvanised supply lines corrode internally and restrict flow. Hot water systems from that era have been replaced, but if you've got a unit older than 15 years, it's on borrowed time. The sequence is usually sewer blockages first, then supply line failures, then hot water.
You can't tell from the surface — a blocked sewer and a collapsed sewer both cause backups and slow drains. The difference matters because a blockage can be cleared with a jet rodder, while a collapse needs excavation and pipe replacement. A plumber we dispatch will run a CCTV camera through the line to see exactly what's happening. The camera shows whether it's roots, grease, a bellied section holding water, or an actual break in the pipe. That inspection takes 30–60 minutes and tells you whether you're looking at a $300 clear or a $3,000 repair.
Prevention is limited once roots have found your pipes — they'll keep coming back. The best approach is regular maintenance clearing every 12–18 months to cut back growth before it causes a full blockage. For long-term solutions, pipe relining seals the joints from the inside and removes the entry points roots exploit. If you've got large trees within 10 metres of your sewer line and terracotta pipes, assume roots are already in there. A CCTV inspection will confirm the extent and help you plan whether clearing or relining makes more sense.
