About Kooyonga
West Torrens Council's May 2026 meeting flagged the Southern Region Waste Resource Authority approach — that's regional waste infrastructure under review, which means potential changes to how sewer and waste services interconnect across Camden Park, Richmond, and the Kooyonga fringe. The 25 Pierson Street Code Amendment is now progressing 140 dwellings plus multi-storey apartments onto a 4.87-hectare commercial site, and that's going to hammer the existing 150mm vitrified clay sewer main on Pierson Street that SA Water's already flagged for capacity upgrades. Add the Brooklyn Park convent redevelopment next door and you've got two major estates loading onto drainage infrastructure that was sized for 1960s density. We copped 14mm on the 2nd and 15mm on the 4th this month — not catastrophic, but enough to flush out every root-compromised joint and undersized stormwater pit in the area. SA Water's also issued warnings across western suburbs about severe tree root intrusions causing sewer blockages, and Kooyonga's mature street trees along Pierson and Azalea are prime suspects. If your drains are gurgling or your toilet's slow to clear after that rain, don't wait — call us and a plumber we dispatch will be there tonight.
City of West Torrens notes
“Item 20.1 - Southern Region Waste Resource Authority Approach to City of West Torrens — considered in confidence under section 90(3)(b)(i) and (b)(ii) regarding commercial and public interest matters”
City of West Torrens
Regional waste authority changes can affect how sewer infrastructure is managed across West Torrens — if service agreements shift, maintenance schedules and emergency response protocols for suburbs like Kooyonga may change. Worth watching for any flow-on effects to local sewer capacity.
“Item 20.2 - Proposed Purchase of Property - Camden Park — considered in confidence regarding potential land acquisition”
City of West Torrens
Council land acquisitions in Camden Park often precede infrastructure projects — stormwater detention, drainage easements, or community facilities. Any earthworks near Kooyonga's boundary could disturb shared drainage lines or alter stormwater flow paths.
“Item 14.1 - West Torrens Dog Park (Marleston) — Administration to investigate accessibility improvements including feasibility of installing an accessible public toilet”
City of West Torrens
New public amenities mean new sewer connections loading onto existing mains. Marleston's adjacent to Kooyonga, and any additional discharge into the shared network increases pressure on already-flagged capacity constraints.
Kooyonga profile
The City of West Torrens is an established inner-western Adelaide council covering suburbs including Hilton, Richmond, Lockleys, Plympton, Mile End, Torrensville, Thebarton, Cowandilla and Novar Gardens. The area is a mix of post-war and mid-20th century detached housing with significant heritage/historic character zones (e.g. Cowandilla), alongside newer infill and medium-density development. The Greater Adelaide Regional Plan identifies West Torrens growth areas plus general infill, signalling continued densification. The combination of older housing stock and active infill development means a wide range of housing ages — from pre-war character homes through mid-century brick and tile to recent townhouses and apartments. City of West Torrens is a densely populated inner-western metropolitan Adelaide council adjacent to Adelaide Airport, with 14 elected members across multiple wards including Airport Ward. The council is actively progressing several infrastructure-relevant initiatives: a community battery installation at Richmond Oval, ongoing Brown Hill–Keswick Creek stormwater catchment works, a road-purpose land acquisition at Ashley Street/Hardys Road, redevelopments at Cowandilla Reserve and Lockleys Oval, and preparation of a Local Area Plan for housing growth and supporting infrastructure. The mix of aging stormwater assets (residents reporting side-entry pit and stormwater flow issues), heritage housing, and growth-driven infill creates sustained demand for emergency plumbing, drainage, electrical and roofing trades — particularly during storm events and around active construction zones.
Pierson Street and Azalea Drive are the two corridors to watch in Kooyonga — Pierson's got the original 150mm vitrified clay sewer that SA Water's flagged for upgrades, while Azalea's on newer PVCU that handles flow better but still connects to the same downstream network. The housing along Pierson is predominantly 1950s–60s brick with copper supply lines and cast-iron internal drains; Azalea's slightly newer stock from the 70s with some early PVC transitions. The sandy Rudosol soil near the golf club means water moves fast through the ground, which sounds good until you realise it also means tree roots travel further hunting for moisture — and they find it in your sewer joints. When the 25 Pierson Street estate starts construction, expect ground disturbance to shift old clay joints and trigger blockages in properties that haven't had issues for years.
When calls come in: Kooyonga callouts cluster in early morning (6–8am) when households hit showers and toilets simultaneously, exposing partial blockages that held overnight. Secondary peak after 6pm when families return home. Winter months see more hot water failures as systems that limped through summer finally give up under heating load.
