Greenhill Road Infrastructure Review: Underground Services Impact
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 is Everard Park's northern boundary — this motion kicks off an investigation that could mean road works right on your doorstep. Once they start cutting into that corridor, expect access headaches and the real chance that older service pipes running off Greenhill get disturbed.
“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 Anzac Highway to Fullarton Road stretch runs right past Everard Park. Three councils coordinating means the scope of any dig could be bigger than a typical local job — and if they're opening up the verge along that alignment, mains and junctions in the area will be worth keeping an eye on.
“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.”
Full Council, 23 March 2026
Unley Oval is a short kick from Everard Park and council is spending serious money keeping it going. That kind of ongoing groundswork means contractor traffic and maintenance activity in the local area — worth knowing if you're waiting on a plumber and wondering why the street's busier than usual.
Everard Park is a tight little suburb wedged between Greenhill Road and the Anzac Highway corridor — and right now the City of Unley is looking hard at what's under and around those main roads. Most homes here are solid inter-war and post-war brick, which means the drainage and supply lines running under them are getting on in age. When council starts digging up the boundaries of a suburb like this, older pipes nearby can cop stress they haven't felt in decades.
Everard Park's got good bones in the homes but the plumbing underneath is running on borrowed time. If you're sitting on a 1940s or 50s brick place, get someone to do a quick camera scope of your sewer line before it becomes an emergency — it'll cost $200-300 now and save you thousands later. The clay soil here doesn't help drainage either, so if you've noticed stormwater sitting around the back garden after rain, that's not just weather — that's your ground telling you the system needs attention. If council's been digging anywhere near your property boundary, keep an eye on your water pressure and listen for dripping sounds under the slab over the next few weeks. Older galvanised pipes can crack under stress and take days to show up as a wet patch. And hot water units — if yours is original to the house, it's on borrowed time. Ring early, not when you've got no hot water in the middle of winter.
- Blocked drains in inter-war and post-war brick homes — clay pipe systems that have been in the ground since the 1940s and 50s, joints breaking down and sediment backing up
- Tree root intrusion in terracotta sewer lines — established gardens throughout Everard Park and roots finding every joint, especially in the older properties near the reserve
- Stormwater backup on the flat allotments near Everard Park reserve — clay soil with poor natural fall means water pools for days after heavy rain, overwhelming the junction with street drainage
- Hot water unit replacements — original storage systems in inter-war and post-war homes finally failing after 70+ years, often positioned awkwardly under slabs
- Leaking galvanised supply pipes under slabs — corrosion in pipes that have never been touched since they were laid in the 1940s-50s, pinhole leaks turning into floods
- Low water pressure from old corroded supply lines — homes on the older side of Everard Park losing pressure as internal corrosion builds up in galvanised steel
- Burst pipes during council roadworks — City of Unley infrastructure projects near Greenhill Road and Anzac Highway adding stress to nearby buried supply and drainage lines
- Slab leaks from failed original plumbing — buried pipes under concrete slabs deteriorating faster when soil is clay-based and acidic, Everard Park's standard soil profile
