Council's just approved a $60,000 sediment transport study for Dry Creek — that's the watercourse running through the eastern edge of Salisbury Heights, and when they're studying sediment movement, it means the stormwater network's under pressure. Resolution 932 from the 12 May meeting confirms it. The Department for Infrastructure and Transport also finished major junction upgrades at The Grove Way and Canterbury Drive late last year, which involved road widening and resurfacing — any time you dig up intersections like that, you disturb the mains underneath. We copped 14mm on the 2nd of May and another 15mm on the 4th, which isn't catastrophic but it's enough to show up any cracks in 45-year-old terracotta sewer lines. Coomurra Rise Estate's adding 24 new homes to the network, and that extra load on ageing infrastructure is when you see pressure drops and backflow issues emerge. If your drains are running slow or you're getting that sulphur smell from the floor waste, don't wait for the next downpour — call us and a plumber we dispatch can get eyes on it before it backs up into the laundry.
City of Tea Tree Gully notes
“Council makes an application to the Stormwater Management Authority for grant funding of up to $60,000 to undertake a sediment transport study for Dry Creek, subject to securing co-contributions from the City of Salisbury and Green Adelaide. Resolution 932.”
City of Tea Tree Gully
Dry Creek runs along Salisbury Heights' eastern edge — when council's studying sediment transport, it means stormwater infrastructure is under load. Properties draining toward the creek corridor are at higher risk of backflow and blockages during wet weather.
“Council endorses the draft submission to the State Planning Commission in response to consultation on Design Standard 1 – Engineering Requirements for Land Division (stage 2). Resolution 933.”
City of Tea Tree Gully
New land division standards affect how estates like Coomurra Rise connect to existing mains. Tighter engineering requirements should mean better connections, but the transition period often exposes weaknesses in the old network when new loads come online.

Salisbury Heights profile
Salisbury Heights falls within the City of Tea Tree Gully local government area in North Eastern Adelaide, South Australia.
Green Valley Drive and Coomurra Drive are where the calls will come from — that's where the original 70s subdivisions went in on heavy clay, and the terracotta sewer lines have been shifting with the soil for decades. The newer Coomurra Rise Estate at the top of Coomurra Drive is all PVC, but those homes are tying into the same ageing council mains, so when the old network backs up, the new builds cop it too. Root intrusion is worst where the street trees are mature — the council plantings along Green Valley Drive have had 40 years to find the joints. If you're in the older stock and haven't had a camera inspection, you're guessing about what's under your slab.
When calls come in: Evening calls are typical — people get home from work, run the dishwasher and washing machine, and that's when a marginal sewer line tips over into a full backup. Weekend mornings also spike when everyone's showering and the hot water unit that's been struggling finally gives out.

Salisbury Heights Plumber FAQ
The study itself won't touch your pipes, but it's happening because stormwater flow and sediment buildup are stressing the drainage network. If your property backs onto the Dry Creek corridor or drains toward it, you're more exposed to backflow during heavy rain. The study may lead to future council works that could disturb connections. For now, if you're getting slow drainage after rain, it's worth getting a plumber to camera the line and check for sediment or root blockages before any major works start.
Gurgling means air is being displaced in the system, which usually points to a partial blockage downstream or a venting issue. In Salisbury Heights, the most common cause is root intrusion in the old terracotta sewer lines — the roots don't fully block the pipe at first, but they slow flow enough to trap air. If it only happens after rain, you might also have stormwater cross-connected to sewer, which is illegal and causes surcharging. Either way, get it checked before the next wet spell turns a gurgle into a backup.
First sign is usually rust-coloured water when you first turn on a tap, especially in the morning. Then you'll notice pressure dropping — takes longer to fill the kettle, shower loses punch. If you see wet patches in the yard or hear hissing near the meter, you've got an active leak. Galvanised pipes in Salisbury Heights are 45+ years old now, and once one section goes, the rest is usually close behind. A plumber we dispatch can pressure test the line and tell you whether it's a patch job or time for a full repipe.
In a 70s Salisbury Heights home, the sewer is almost certainly terracotta, which cracks and lets roots in. Supply lines are likely galvanised steel, which corrodes from the inside out. Hot water is probably an electric storage unit that's been replaced once or twice, but if it's original, it's a ticking bomb. Gully traps and sewer vents are often the first to fail because they're exposed to weather. The sequence is usually: blocked drains first, then supply pressure drops, then hot water dies. Get a plumber to do a full inspection if you haven't had one in the last five years.
A blocked sewer backs up, you clear it, and it works again — at least for a while. A collapsed sewer backs up, you clear it, and it backs up again within days or weeks because the pipe itself has failed and debris keeps accumulating at the break point. The only way to know for sure is a CCTV drain camera inspection. A plumber we dispatch can run a camera through and show you exactly what's happening — root mass, joint displacement, or a full collapse. That footage also helps if you need to claim on insurance or negotiate with council about the boundary trap.
Get your sewer line camera-inspected every few years, especially if you've got mature trees near the line — figs, peppercorns, and liquidambars are the worst offenders. Replace flexi-hoses under sinks and on washing machines every five years, no exceptions. If your hot water unit is over ten years old, budget for replacement before it floods the laundry. And if you notice slow drains after rain, don't ignore it — that's the early warning that your stormwater and sewer might be cross-connected or your gully trap is failing.
