Hallett Cove in four facts
94.7% separate houses
The 2021 Census counted almost only houses in the suburb: 94.7% separate houses, 5.1% semis or townhouses and 0.1% flats.
Owners, mostly
45.4% of homes were owned with a mortgage and 39.2% outright. 14.2% were rented, about half the South Australian rate.
Marion's drain network
City of Marion manages 261 km of stormwater pipes, culverts and box drains, 1007 km of kerbing and spoon drains, and 6946 stormwater pits.
Kerb connections in steel
Marion's July 2025 permit conditions say every stormwater connection to the kerb must use a steel stormwater outlet.
New driveway, new kerb outlet
A driveway job often disturbs the stormwater pipe that runs under the verge. Work across Council land needs a permit under section 221 of the Local Government Act 1999, and Marion's conditions set some clear distances.
The crossover must sit at least 0.5 metres from existing infrastructure such as side entry pits and drains, and at least 2.0 metres from street trees. Where the stormwater pipe meets the kerb, the outlet has to be steel. Ask your plumber and concreter to plan the pipe and the driveway together so neither has to be redone.
Getting ready for a big storm
Clear the roof water path
Gutters, downpipes and any silt pits on your block are where water backs up first.
Check the kerb outlet
If water sits behind the kerb or bubbles out of the verge, the pipe under the nature strip may be blocked or crushed.
Report street pits to Council
Side entry pits in the road are part of Council's network, so report a blocked one to Marion.
Why storms are on Marion's radar
Council's stormwater plan for 2024 to 2034 reports good performance on climate resilience, with an awareness of surge events that need catering for as storms become more severe. For private drains, the best defence is a clear pipe and a sound outlet. See our stormwater page for what a plumber checks.
SA Water and the sewer
SA Water provides the sewer, but we couldn't confirm its rule on where its pipe stops on your property. Check with SA Water before anyone digs near the front boundary. For everyday jobs: blocked drains, hot water replacement, heat pump hot water and burst pipes. Also in the City of Marion: Marion.
What we would do
If you're replacing a driveway, get the stormwater checked at the same time. It's far easier to lay a new pipe and steel outlet while the verge is already open than to break the new concrete later. And if water backs up in the yard during rain, have a stormwater specialist camera the line before winter rather than in the middle of a storm.
