Greenhill Road Infrastructure Works — Expect Disruptions
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
This is the starting gun on potential works along Greenhill Road — the northern boundary of Hyde Park. Nothing's been dug up yet, but if this moves forward, expect disruption to kerb and footpath infrastructure in an area where older drainage connections run close to the surface.
“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.”
Full Council, 23 March 2026
That stretch from Anzac Highway to Fullarton Road runs directly past Hyde Park's front door. Three councils coordinating on the same corridor means if works do get approved, they'll be bigger and longer than a standard kerb job — which puts older residential connections along King William Road and Greenhill Road under more pressure than usual.
Hyde Park sits tight between Greenhill Road and Unley Road — older character homes, narrow blocks, and pipes that in some cases have been in the ground since the fifties. City of Unley is currently looking at road and footpath works along Greenhill Road, which runs right along the northern edge of the suburb. Any digging up that corridor can disturb ageing stormwater and sewer connections in streets that feed off it — so if you're in Hyde Park and something's backing up or draining slow, it's worth knowing what's happening at council level before you assume it's just your problem.
Hyde Park's age works against you plumbing-wise. The houses are solid, but the pipes underneath are tired. If you're renting or just moved in, ask the owner or check the rates notice to see when the house was built — anything pre-1975 almost certainly has terracotta or clay sewer and stormwater, and you should know that going in. Tree roots are a fact of life on the bigger blocks, so if you've got mature trees and suddenly a slow drain, that's your answer nine times out of ten. With City of Unley working on Greenhill Road, if your drains start acting up, give them a call and ask if there's any active digging in your street. Half the time a slow drain during council works fixes itself once they're done — if it doesn't, then you know it's something on your property. Don't wait for a full backup to call someone out; slow drains are cheap to clear, backups aren't.
- Blocked drains from tree root intrusion in clay and terracotta pipes — the established garden blocks in Hyde Park, especially those with mature trees, see this constantly because the old pipes are porous and roots find them easy prey
- Slow stormwater drainage on the flat allotments near Hyde Park reserve after rain — clay soil, no natural fall, and old brick or concrete kerbing connections that can't handle volume
- Hot water unit failures in period homes from the 1950s–1970s — most still have original or undersized systems that were never meant to last this long
- Sewer odour and backflow where older junction connections have shifted or cracked — especially where Greenhill Road council works are disturbing the corridor
- Leaking taps and corroded internal copper pipework in pre-1970 homes — the older the house, the more likely the pipes are eating themselves from the inside
- Stormwater backup after heavy rain on properties with original brick kerbing connections — the connections haven't moved in sixty years but they're not watertight anymore
- Burst or pinhole leaks in old copper pipes under pressure — common in homes built in the 1950s and 1960s where the copper was thinner gauge
- Failed or undersized sewer connections where properties were subdivided — narrow blocks in Hyde Park often have older mains that weren't designed for dual occupancy
- Slow drainage in kitchens and bathrooms in homes with original lead traps — common in 1950s builds and often clogged with decades of grease and sediment
- Gutter and downpipe blockages that overflow into stormwater systems — older homes on Hyde Park's elevated northern side shed leaves straight into aging infrastructure
