Greenhill Road Infrastructure Works — Clay Pipe Risk Alert
City of Unley · Council intelligence · Last updated April 2026
“NOTICE OF MOTION FROM COUNCILLOR M BRONIECKI RE: WALKING AND CYCLING INFRASTRUCTURE ON GREENHILL ROAD”
Full Council, 23 March 2026
Greenhill Road runs right along Millswood's northern boundary. A notice of motion like this is the first step before the excavators show up — when cycling and walking infrastructure gets built, there's usually kerb work, drainage changes, and service relocations involved. If you're on a street that connects to Greenhill Road, it's worth knowing your drainage is in good shape before works start.
“Administration work with staff from the City of Adelaide and the City of Burnside to investigate the provision of improved walking and cycling infrastructure along the southern boundary of the Adelaide Park Lands fronting Greenhill Road from Anzac Highway to Fullarton Road.”

This is a three-council job running from Anzac Highway all the way to Fullarton Road — that corridor runs straight past Millswood. When three councils start coordinating on a stretch like that, the groundwork is significant. Older stormwater and sewer lines in the area can cop pressure when heavy machinery is working nearby, so if your drains have been slow or your spouting hasn't been looked at in a while, don't leave it.
“The total cost to Council of maintaining the playing surface at Unley Oval for football and cricket differs from year to year as there are various factors that can impact cost. For the 2024-25 financial year, the total cost to Council was $85,172 (excluding GST). This comprises a cost of $28,372 for football (excluding temporary fencing for Sturt Football Club matchdays) and $56,800 for cricket.”

Not a direct plumbing issue, but Unley Oval is a short walk from Millswood and the irrigation and drainage infrastructure underneath those surfaces is serious gear. Heavy oval maintenance activity nearby — especially around match season — can mean extra load on local stormwater connections. Worth keeping in mind if your yard drains slowly after rain.
Millswood is sitting right on the edge of the Greenhill Road corridor, and the City of Unley is actively looking at road and infrastructure works along that stretch. That matters if you're in a 1920s or 1930s timber-and-iron home here — ground movement from nearby digging can stress old clay pipes that were never built to handle it. Nothing's been ripped up yet, but the planning is moving and it pays to know what's coming before your drain backs up on a Sunday night.
If you're renting or own in Millswood, you've probably noticed the older homes around here have their own quirks — especially when it comes to water and drainage. The houses built pre-war are solid, but original clay pipes and aged copper fittings don't fix themselves. When the City of Unley starts moving earth along Greenhill Road, that's when pre-war homes in Millswood start showing their weak points. A quick inspection of your sewer line and hot water setup could save you a nasty call-out on a Sunday.
- Blocked drains in pre-war homes with original clay sewer lines — roots get in at every joint
- Hot water unit failures in older weatherboard homes with units that haven't been replaced in 15+ years
- Leaking taps and corroded copper pipework in 1920s–1940s homes with original fittings
- Spouting and downpipe disconnections — cast iron spouting rusts through and pulls away from fascia
- Slow-draining showers and basins from partial blockages in underslab clay drainage
- Ground stress on clay pipes from nearby council infrastructure works along Greenhill Road corridor
- Water seepage issues after heavy rain in homes with degraded underground drainage
