City of Unley is about to put machinery into the ground along the Unley Road corridor. The $13.18 million renewal program kicking off in July covers drainage, footpaths, and stormwater infrastructure — and when contractors start cutting through bitumen in a neighbourhood this old, what's underneath gets disturbed. The ceramic and earthenware sewer lines running under Fullarton's residential streets weren't built for the vibration loads modern plant generates, and most of them are already offset or cracked from 60 years of seasonal ground shift. That heavy downpour in early May didn't help — saturated ground expands, and the lateral pressure that puts on old pipe joints is exactly how a borderline blockage turns into a sewage backup. If your drains have been off since the rain hit, that's worth taking seriously.
City of Unley notes
“Draft 2026-27 Annual Business Plan and Budget: Capital Renewal Program of $13.18M net covering renewal of existing assets including roads, footpaths, drainage, stormwater, and infrastructure (Resolution No. C0043/26)”
City of Unley
When council renews drainage and stormwater assets, they expose everything connected to them. Old private sewer and water connections in Fullarton will get disturbed during this program — that's when failures that were years in the making suddenly show up.
“Business Precinct Management Plan: Unley Road business precinct streetscape upgrades and footpath works funded through a separate rate from July 2026 (Resolution No. C0042/26)”
City of Unley
Footpath and road reserve works along Unley Road mean excavation close to residential and commercial service connections. Properties on side streets feeding into the Unley Road corridor are worth monitoring for drainage changes once the dig-work starts.
“Mary Place road closure (Unley) adjacent to Charles Walk Drainage Reserve — road parcel sold for development, works will involve drainage reserve and stormwater infrastructure (Resolution No. C0037/26)”
City of Unley
Development next to a stormwater drainage reserve changes flow patterns and loading across the connected catchment. If your property sits downstream of Charles Walk, it's worth knowing this works program is running.

Fullarton profile
Fullarton sits in the City of Unley — inner southern Adelaide, predominantly 1950s-70s brick veneer and sandstone cottages. Earthenware sewer lines, galvanised supply pipes, and a flat drainage profile on the eastern side of the suburb where allotments around Fisher Street don't shed water easily. The Unley Road business precinct cuts through the suburb and is scheduled for footpath and road reserve works from July 2026 — part of a $13.18 million renewal program that will mean contractors in the ground across the council area for the next 12 months.
Fullarton is mostly 1950s and 60s construction — brick veneer and rendered sandstone cottages where earthenware was standard for sewer lines and galvanised steel was the default supply pipe. Neither ages well. Galvanised internal scaling narrows the bore over decades until it perforates; earthenware sewer lines grow brittle, crack at the joints, and invite root intrusion the moment ground moisture shifts. Light Avenue and the residential pockets running off it have some of the oldest pipe runs in the suburb — the street trees here have had 60-plus years to locate every weak joint. Broadmeadows Road tells the same story. The blocks along Fisher Street have a different problem: flatter allotments mean stormwater has less natural fall to work with, and during sustained downpours the pits back up before the system can clear.
When calls come in: No call data yet for Fullarton. Based on housing stock and demographics, expect morning calls (6-8am) for hot water failures and evening calls (5-8pm) for blocked drains discovered after work.

Fullarton Plumber FAQ
Not directly in most cases, but the indirect risk is real. When heavy machinery operates near old underground infrastructure — cutting footpaths, excavating for drainage upgrades, running compactors along road reserves — vibration transmits through the soil to any private drain within range. Ceramic and earthenware sewer lines are particularly vulnerable because the material is brittle after 60 years in the ground and many joints are held in place only by compacted soil and inertia. The sections most exposed are where your private drain runs parallel to, or beneath, a footpath council is renewing. If you notice a sudden change in drain behaviour after works commence near your property, get a camera inspection done before assuming it'll resolve — the connection between ground disturbance and a pipe failure isn't always obvious without seeing inside the line.
Depends what slow means. A single fixture that slugged for a day then cleared is usually a partial blockage loosening under water pressure — monitor it. But if multiple fixtures are backing up simultaneously, or you're hearing gurgling from floor wastes or external gullies when you flush the toilet, the blockage is in the main sewer line, not a branch, and that won't self-resolve. Fullarton's earthenware sewer lines crack at the joints under ground movement and accumulate debris at those crack points over time. A blockage sitting inside a cracked section is a fundamentally different repair to one in a structurally intact pipe — jetting a compromised line without knowing the condition can dislodge debris into a collapse. Camera inspection first, then treatment based on what the camera shows.
The clearest sign is when your sewer backs up specifically during heavy rain — if flushing the toilet becomes difficult, or floor wastes in the laundry gurgle when it's raining hard, you've likely got downpipes cross-connected to the sewer. Older Fullarton homes often had downpipes routed straight into the house sewer as a quick fix on extensions and renovations done before development approval requirements tightened. It's illegal under current plumbing standards and SA Water's requirements. Call us and a plumber we dispatch can trace your downpipe connections and re-route to dedicated stormwater, which also takes the wet-weather surge off your sewer and stops the backups.
The tank itself, under Adelaide's mildly mineralised supply, typically runs 10-15 years before the anode depletes and internal corrosion takes hold. What catches most Fullarton homeowners off guard is the surrounding infrastructure — in a 1960s or 70s home, the supply connections feeding the unit, the cold water inlet fittings, and the relief valve discharge pipe are often original or early-replacement components, not the tank. The unit may fail first, or the connections might. When a plumber we dispatch assesses a hot water replacement, they check the full service configuration — fitting a new unit to deteriorated connections produces a second call-out within 12 months, which is how most avoidable hot water failures unfold in period homes.
Galvanised steel supply pipes corrode from the inside out — iron oxide scale builds up on the pipe walls over decades, steadily narrowing the bore until flow is severely restricted. In Fullarton's 1960s housing stock, original galvanised pipes that haven't been replaced are now 60-plus years old and most of the bore is consumed by scale. You'll usually notice it first at the hot taps — those runs are longer to reach the hot water system — then progressively at cold taps too. Flushing the system temporarily improves flow, but the scale keeps building. Once multiple outlets across the house are affected simultaneously, the system needs a full repipe. There's no practical way to clean galvanised pipe at that stage of internal corrosion.
A sewer smell from floor wastes or external gullies during dry weather is usually a dry trap — the water seal has evaporated and sewer gas is venting back through the fitting. On a floor waste you rarely use, half a bucket of water reseals it immediately. If the smell persists after refilling traps, or it's coming from the ground surface around a gully rather than the fitting itself, the more likely cause is a cracked pipe leaking sewer gas into the surrounding soil. In Fullarton, cracked earthenware under loaded areas — driveways, paved outdoor areas, anywhere heavy vehicles have parked — is common. A pressure test or camera confirms whether it's a trap issue or structural damage worth repairing.
