About Ascot Park
City of Marion's pushing ahead with the Centres Zone Adjustments Code Amendment — sites at 26-28 Daws Road and 66 Sixth Avenue in Ascot Park are flagged for rezoning to General Neighbourhood, which means higher-density infill is coming and the old reticulation underneath those blocks will cop more load than it was ever designed for. The early May rain — 14mm on the 2nd, another 15mm on the 4th — has kept the clay soil saturated, and that's when the 1950s-era clay sewer pipes start weeping at the joints. SA Water's just finished 612 metres of new water main in Ascot Park, which is good news for supply pressure but means some homes are now connected to new infrastructure via old copper runs that weren't designed for the improved flow. If you're in one of the post-war brick homes near the reserve, the flat ground and poor drainage fall make stormwater backup a real risk when the soil's already holding water. The EPA's Groundwater Prohibition Area still covers Ascot Park due to historical TCE contamination — mains water's fine, but if you've got an old bore connection that was never decommissioned, now's the time to sort it. Call us when the drains slow down or the hot water goes cold — we'll get a plumber out who knows what's under these streets.
City of Marion notes
“Centres Zone Adjustments Code Amendment (2025/2026) proposes rezoning sites at 26-28 Daws Road and 66 Sixth Avenue in Ascot Park to General Neighbourhood to support higher-density infill.”
City of Marion
Higher-density builds on old reticulation means more load on sewer and water mains that were sized for single dwellings — expect pressure and drainage issues to surface on neighbouring properties once construction ramps up.
“SA Water's 2024-25 Annual Report highlights the installation of 612 metres of new water mains in Ascot Park to upgrade the local network.”
City of Marion
New mains improve supply pressure, but homes still connected via original copper runs may see those old pipes fail faster under the improved flow — worth checking your internal plumbing if you've noticed pressure changes.
“Ascot Park is subject to an EPA-mandated Groundwater Prohibition Area (GPA) restricting bore water use due to historical TCE contamination.”
City of Marion
If your property has an old bore that was never decommissioned, it's a compliance issue — a plumber can check for legacy connections and advise on proper capping.
Ascot Park profile
City of Marion has a diverse housing stock ranging from post-war brick homes in suburbs like Ascot Park, Edwardstown, and Mitchell Park, to coastal properties in Hallett Cove, Marino, and Seacliff Park, and newer developments in Sheidow Park and Trott Park. Many older homes feature ageing plumbing, electrical wiring, and roofing that frequently require emergency trade callouts. The council is undergoing significant urban infill and medium-density redevelopment along key corridors such as Marion Road and Sturt Road, increasing demand for trade services across both established and new dwellings. City of Marion is one of South Australia's largest metropolitan councils, located in Southern Adelaide approximately 10km south of the CBD, covering 55 square kilometres and home to over 95,000 residents across 25 suburbs. The area includes major commercial hubs (Westfield Marion, Castle Plaza), industrial zones in Edwardstown and Mitchell Park, and coastal suburbs along the Gulf St Vincent. The mix of older established suburbs, coastal cliff-top properties prone to storm damage, and ongoing major infrastructure projects like the Marion Basketball Stadium redevelopment generates consistent demand for 24/7 emergency trades including plumbing, electrical, gas, locksmith, and roofing services.
The streets closest to Ascot Park reserve — think the lower sections of Doreen Street and Doris Street — sit on the flattest ground in the suburb, which is why stormwater pooling and sewer backup hit those blocks hardest after rain. The post-war brick homes along Marion Road and the side streets off it were built with clay sewer pipes and copper supply lines that are now 60-70 years old; the failure pattern is usually root intrusion first, then pinhole leaks in the copper, then hot water system collapse. Newer infill around Sixth Avenue is on plastic pipe, but it's often tied into the same old sewer mains — so a blockage downstream affects everyone on the run.
When calls come in: Most calls from Ascot Park come through between 6pm and 10pm on weekdays — people get home from work, run the shower or dishwasher, and that's when the slow drain or cold water becomes impossible to ignore. Weekend mornings are the second spike, usually hot water failures discovered when the first person tries to shower.
