Council's veteran tree review is hitting Tusmore hard right now — inspections along Greenhill Road and in Tusmore Park are using sonic tomography to assess root systems, which means anyone with terracotta sewer lines near those mature gums should be paying attention. The 14mm and 15mm rain events early May have already saturated the reactive clay soils that run through the suburb, and that's when the old earthenware pipes start moving at the joints. Tusmore's housing stock is predominantly inter-war character homes with original clay drainage — the kind that cracks when the ground swells, then lets roots in when it shrinks back. We've seen the pattern before: heavy rain, soil movement, then a week later the toilet's backing up. The rekerbing program rolling out through 2026-27 will disturb some of those ageing service connections too. If your drains are slow after this wet start to May, don't wait — call us and a plumber we dispatch can get a camera down before it becomes a dig-up job.
City of Burnside notes
“Review of veteran tree management practices is underway, including detailed inspections of veteran trees along Greenhill Road and Portrush Road, as well as trees in Hazelwood Park Reserve and Tusmore Park, incorporating aerial inspections and sonic tomography.”
City of Burnside
Sonic tomography maps root systems — if council's assessing root spread near Tusmore Park and Greenhill Road, homeowners on those streets with terracotta drains should expect root intrusion issues to be confirmed, not discovered for the first time.
“Rekerbing 2026-27 program to replace kerb and guttering across various streets in the City of Burnside.”
City of Burnside
Kerb replacement means excavation along the footpath zone where service connections run — older clay and galvanised connections in Tusmore are vulnerable to cracking or joint separation from ground disturbance.
“Ongoing catchment-wide flood mitigation works under the Brown Hill Keswick Creek Stormwater Project.”
City of Burnside
Tusmore drains into this catchment — any upstream capacity improvements reduce backflow risk during heavy rain, but properties with undersized or blocked private stormwater lines won't benefit until their own systems are cleared.

Tusmore 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.
Tusmore Avenue, Stirling Street, and Kennaway Street near Tusmore Park are the worst streets for root intrusion — the mature gums and elms have had 80-plus years to find every terracotta joint. The housing along these streets is predominantly 1920s-40s character stock, which means original clay sewer lines that were laid before plastic was an option. When the reactive clay soils swell after rain then shrink back in dry spells, those rigid pipes crack at the joints and roots follow the moisture gradient straight in. The newer infill around the edges of the suburb has PVC drainage, but the water supply often ties into the same aged mains infrastructure.
When calls come in: Tusmore calls typically come through in the early evening — 5pm to 8pm — when people get home from work and discover the toilet won't flush or the shower's backing up. Weekend mornings are also common, especially after Friday night rain events when the damage has had time to show.

Tusmore Plumber FAQ
Rekerbing work involves excavation along the road edge and footpath zone, which is exactly where your service connections run from the main to your property boundary. If your home predates 1980, those connections are likely original clay or galvanised — materials that don't handle vibration or ground disturbance well. Watch for new leaks, wet patches near the footpath, or a sudden drop in water pressure in the weeks after kerb work passes your property. If you notice anything, get a plumber to inspect before minor damage becomes a full replacement job.
Slow drains after heavy rain in Tusmore are usually one of two things: surface debris washing into grated drains, or soil movement cracking old clay pipes and letting roots in. If it's just one fixture (like a floor waste), debris is likely. If multiple fixtures are slow — toilet, shower, laundry — that's a main drain issue and probably root intrusion or a joint failure. The reactive clay soils here swell when wet and shrink when dry, which stresses rigid terracotta pipes at every joint. A CCTV inspection will show exactly what's happening before you commit to any clearing or repair.
Galvanised steel pipes corrode from the inside out, so you won't see rust on the outside until it's too late. The warning signs are: brown or orange-tinged water when you first turn on a tap, reduced water pressure that's worse at the furthest tap from the meter, and pinhole leaks appearing at fittings or elbows. In Tusmore's inter-war and mid-century homes, galvanised supply lines are often 50-70 years old — well past their expected lifespan. If you're seeing any of these signs, a plumber can pressure-test the line and advise whether you need spot repairs or a full repipe.
A 1930s character home in Tusmore typically has terracotta sewer and stormwater drains, galvanised or early copper water supply, and cast iron vent stacks. The sewer lines are the first to fail — root intrusion at joints is almost guaranteed after 90 years. Next is the galvanised supply, which corrodes internally and restricts flow. Hot water systems in these homes are often undersized for modern use and sitting on original pipework that's scaled up inside. Expect to address drains first, then supply lines, then hot water — that's the typical failure sequence in heritage eastern suburbs housing.
A blocked drain clears with a jet or electric eel and stays clear for months. A collapsed drain clears temporarily, then blocks again within weeks — because the pipe wall has failed and debris keeps catching at the same point. The only way to know for certain is a CCTV drain camera inspection. The camera shows whether the pipe is intact with a root ball (clearable), cracked with roots growing through the wall (needs relining or patching), or fully collapsed (needs excavation and replacement). In Tusmore's clay soils, cracks often turn into collapses after a few wet-dry cycles.
Cold inlet water in winter is around 10-12°C compared to 20°C+ in summer — your hot water system has to work harder to reach the same output temperature, which means the tank depletes faster. In older Tusmore homes, the problem is compounded by scaled-up elements (reducing heating efficiency) and undersized tanks that were fine for 1970s water use but can't keep up with modern showers and dishwashers. If you're running out of hot water regularly, a plumber can check element condition, flush sediment, and advise whether a larger tank or continuous flow system makes sense for your household.
