City of Unley's draft 2026-27 budget is out for consultation through 25 May, with $13.18M earmarked for capital renewal works across the council area — that includes road resurfacing on Collins Street between Campbell Road and Dudley Street, plus Belgrave Court from Unley Road to the end. Both streets sit on Parkside's western edge where the original 1920s clay sewer mains run tight to the kerb. May's already dropped 29mm across two hits early in the month, and that's enough to get the Bay of Biscay clay moving again after a wet April. The big development news is the proposed 156-unit Regis Aged Care facility at 12-30 Glen Osmond Road — that's a serious new load on sewer infrastructure that's already running at capacity. If you're on a street feeding toward Glen Osmond Road or the Greenhill Road corridor, now's the time to get a camera down your drains before the next heavy rain. Call us and a plumber we dispatch can run a CCTV inspection same day.
City of Unley notes
“Draft 2026-27 Annual Business Plan and Budget endorsed for community consultation, including Capital Renewal Program requiring net funding of $13.18M (Resolution C0043/26)”
City of Unley
Road renewal works on Collins Street and Belgrave Court mean heavy machinery on Parkside's western edge — vibration and soil disturbance can crack already-weakened clay sewer joints on adjacent properties.

Council's infrastructure works are ongoing across Unley — any trenching or resurfacing near your property boundary is worth monitoring for drainage changes or new leaks appearing after completion.

Parkside profile
Parkside sits tight against Greenhill Road, and City of Unley is looking hard at what goes in the ground along that corridor. Any road or footpath work near a suburb like this — older homes, established trees, clay soil — tends to shake things loose underground. Expect pressure on aging stormwater and sewer lines close to the boundary, and if you're on a street that connects to Greenhill Road, it's worth keeping an eye on what's coming.
The worst streets for sewer problems in Parkside run parallel to Greenhill Road — think Young Street, Robsart Street, and the lanes feeding toward Glen Osmond Road. These blocks have the oldest housing stock, the biggest established trees, and clay sewer mains that were laid before anyone thought about root barriers. The homes closer to Fullarton Road tend to be slightly newer 1940s-50s builds with marginally better pipe condition, but the same reactive clay soil means joint failure is still common. When we see a cluster of calls from one street, it's usually because one property's root problem has spread to the shared main — if your neighbour's had a blockage, yours isn't far behind.
When calls come in: Parkside 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 when families are home and putting load on the system.

Parkside Plumber FAQ
Road resurfacing itself doesn't touch your sewer or water mains directly, but the heavy machinery and vibration can shift clay soil enough to crack already-weakened pipe joints. If your property connects to the sewer main running under or near these streets, watch for slow drainage or gurgling in the weeks after works finish. A CCTV inspection before and after gives you a baseline — if something cracks, you'll know when it happened and can pursue the right channels.
Slow drains after rain in Parkside usually mean one of two things: either your stormwater system is backing up because gutters and pits are blocked with leaf debris, or your sewer line has root intrusion that swells when groundwater rises. The test is simple — if it's only floor wastes and outdoor drains, it's likely stormwater. If toilets and sinks are also slow, roots are in your sewer. A plumber we dispatch can jet the line and run a camera to confirm which system is compromised.
Galvanised steel pipes in Parkside homes typically last 50-70 years before internal corrosion restricts flow. Early signs include rusty water first thing in the morning, reduced pressure at taps furthest from the meter, and pinhole leaks appearing under concrete paths or in walls. Once you see one pinhole, the whole run is compromised — patching buys you months, not years. A plumber we dispatch can pressure test the line and advise whether you're looking at spot repairs or a full copper or PEX repipe.
Homes from this era typically have vitrified clay sewer pipes, galvanised steel water supply, and cast iron waste stacks. The sewer goes first — root intrusion and joint failure from soil movement are almost universal by now. Next is the galvanised supply, which corrodes from the inside out. Cast iron waste pipes last longer but eventually scale up internally, reducing flow to a trickle. If you've owned the home less than 10 years and haven't had a full plumbing inspection, assume at least one of these systems is near end of life.
A blocked sewer clears with a jet and stays clear for months — roots or debris were the problem, but the pipe is intact. A collapsed sewer clears temporarily then blocks again within days or weeks, often in the same spot. The only way to know for certain is a CCTV camera inspection after jetting. The camera shows whether the pipe walls are intact, cracked, or completely failed. A plumber we dispatch will run the camera as standard after clearing a stubborn blockage — it's the only way to quote accurately for what comes next.
A 156-unit facility adds significant load to the sewer main it connects to. SA Water will require the developer to upgrade infrastructure to handle the new capacity, but the existing downstream network — including older clay mains serving nearby residential streets — may see increased flow and pressure. If you're on a street that feeds toward Glen Osmond Road, it's worth getting a baseline CCTV inspection now. Any cracks or root intrusion will only get worse once the new load comes online.
