Stormwater Drains Adelaide
Stormwater Drain Solutions from Your Adelaide Neighbourhood Plumbers
When the first serious rain of winter hits Adelaide, water finds every weakness in your stormwater system at once. Blocked downpipes overflow into wall cavities. Pipe Relining repairs let water pool against foundations. Undersized pits flood the garden instead of clearing it. Most of the time, the problems were building quietly through summer – it just took the storm to announce them.
We’ve spent 15+ years across Adelaide diagnosing with CCTV Drain Inspections, repairing, and installing private stormwater systems for local homeowners. Whether it’s a collapsed earthenware pipe under a Norwood paver path, a pit that’s lost its fall in Salisbury’s clay soil, or a full new-build drainage design for a Mount Barker block, our licensed team (Licence PGE #360928) turns up with the right equipment, explains what we’ve found in plain English, and fixes it properly the first time.
Every job is backed by our Lifetime Workmanship Guarantee, 260+ five-star Google reviews from Adelaide neighbours, and a metro-wide team that treats your home like it’s next door to ours – because for most of our jobs, it is.
Why Adelaide's Conditions Are Tough on Stormwater Drains
Stormwater systems don’t fail randomly. After 15+ years across Adelaide, we see the same patterns repeat, and they’re almost always tied to where the home sits on the map.
Reactive clay soil in the north and inner suburbs. In Salisbury, Elizabeth, and much of Adelaide’s northern plain, clay swells in winter and shrinks back in summer. That constant movement cracks pipe joints, misaligns pits, and flattens the fall gradient your stormwater relies on.
Century-old earthenware pipes in the inner east. Homes in Norwood, Stepney, and St Peters often still have original earthenware stormwater in the ground, with mature plane trees and jacarandas sending roots that cause blocked drains into every joint gap
- Reactive clay soil cracking pipe joints in the north
- Century-old earthenware pipes failing in the inner east
- Tree root intrusion under mature plane trees and jacarandas
- Salt-air corrosion attacking metalwork in beach suburbs
- Heavy rainfall load scouring pits in the Adelaide Hills
- Original installs that no longer meet AS/NZS 3500.3
Salt air in the western beach suburbs. Coastal homes in Henley Beach and Semaphore deal with accelerated corrosion on galvanised downpipes, metal grates, and pump components. What lasts 40 years inland often fails in 15 near the coast.
Modern stormwater installations are governed by AS/NZS 3500.3, the Australian Standard for stormwater drainage. When we repair or install stormwater infrastructure, we bring older systems into compliance with that standard – which is why our work holds up through Adelaide seasons the original installation couldn’t.
Stormwater Drains in Adelaide: Who Owns and Maintains Them?
In Adelaide, stormwater responsibility is a three-way split most homeowners never get explained clearly – and it’s the single most common question our reception team fields.
SA Water doesn’t manage stormwater at all. Their remit is mains drinking water and sewerage. If you’ve ever phoned them about a flooded backyard or a blocked downpipe, you’ll have been politely redirected.
Your local council looks after the public stormwater network. That means the kerb-side inlets at the end of your street, the main pipes running under the road, and the wider drainage system that carries rainfall away from your suburb. If a council inlet is blocked or a street drain has collapsed, that’s their job to fix.
Everything on your property is yours. Every downpipe, every underground stormwater pipe across your block, every soakage pit, every grate, every connection to the street. From the roof down and from the boundary in, it’s private infrastructure that a licensed plumber needs to maintain.
That’s where we come in. If it’s on your side of the property boundary, we handle it. From a single blocked downpipe to a full system redesign, our licensed team (Licence PGE #360928) diagnoses, repairs, upgrades, and installs private stormwater infrastructure across metropolitan Adelaide.
Not sure where your responsibility ends and your council’s begins? Give our friendly team a call on (08) 8152 9100. If the problem is council’s, we’ll tell you straight rather than leave you wondering.
Signs Your Stormwater Drain Needs a Plumber's Attention
Most stormwater failures give warning before they turn into flooded rooms or cracked slabs. If any of the below sound familiar, it’s worth a look sooner rather than later.
- Water pooling in the garden or lawn after rain
- Damp patches on internal walls near ground level
- Fine cracks in foundations or external brickwork
- Downpipes overflowing at the top during rain
- Gutters draining slowly or backing up at downpipes
- Sinking or uneven ground above an underground pipe
Many of these same signs overlap with general blocked drains issues inside the home, so it pays to have the problem properly diagnosed before deciding on a fix. If you’re seeing two or more of these, book a proper inspection. Catching a hairline pipe crack in autumn costs a fraction of rebuilding a section of foundation in spring.
How We Diagnose and Repair Stormwater Drains in Adelaide
Before we quote, we diagnose. Before we dig, we consider every option that doesn’t require digging. That philosophy saves Adelaide neighbours thousands of dollars a year.
Step 1: CCTV inspection. We feed a waterproof camera into your stormwater line and trace it from access point to discharge. You see the footage with us on a live monitor. Cracks, collapses, root intrusion, offset joints, partial blockages – all visible in real time, with exact distance readings. Full detail on our CCTV drain inspections service.
Step 2: Matched-fix recommendation. Based on what the camera shows, we explain your options in plain English and give you an upfront quote before any work starts. For light blockages, that’s often a hydro-jet clean. For cracked or root-damaged pipes, we’ll usually recommend pipe relining – a trenchless method where a resin-impregnated liner is cured inside the existing pipe, forming a new structural pipe without excavation.
- On-site CCTV inspection with live monitor footage
- Plain-English options and an upfront written quote
- Trenchless pipe relining where excavation isn't needed
- Targeted dig and replace for collapsed or non-compliant runs
- Every install brought into AS/NZS 3500.3 compliance
- Photos or CCTV footage delivered for your records
Step 3: AS/NZS 3500.3 compliant repair. All work we install or replace is brought into line with AS/NZS 3500.3, the Australian Standard for stormwater drainage. That covers pipe falls, pit sizing, connection methods, and discharge – the technical details that determine whether your system still works in 20 years or fails in five.
Step 4: Clean-up and sign-off. Our Clean Home Guarantee means we leave your property cleaner than we found it. You get photos or CCTV footage of the completed repair for your records, and the work is backed by our Lifetime Workmanship Guarantee.

Stormwater Drain Questions Adelaide Neighbours Often Ask
Q: Who's responsible for stormwater drains in Adelaide - me, my council, or SA Water?
SA Water doesn’t manage stormwater at all. Your local council handles the public network – street inlets and main drains. Everything on your property, from downpipes to underground pipes to pits, is the homeowner’s responsibility. That’s the part we look after.
Q: Do your stormwater repairs meet Australian Standards?
Yes. All work we carry out meets AS/NZS 3500.3, the Australian Standard for stormwater drainage, and the broader AS/NZS 3500 plumbing code. Our team holds Licence PGE #360928 and operates under the oversight of South Australia’s Office of the Technical Regulator (OTR). That means pipe falls, pit sizing, connection methods, and discharge points on every install or replacement we do are brought into line with current standards, not just patched to last another winter. If you ever need to prove compliance for insurance or a property sale, we can document the work.
Q: What are the signs I've got a stormwater problem - and how fast can you respond?
The most common early signs are water pooling in the garden after rain, damp patches on internal walls near ground level, downpipes overflowing at the top, gutters draining slowly, and musty smells around garages or under-floor spaces. If you’re seeing two or more, book a proper diagnosis before small cracks become foundation damage.
For genuine stormwater emergencies, we target a 60-minute response across metropolitan Adelaide, 24/7*. Call (08) 8152 9100 and we’ll have a licensed plumber on the way.
Q: Can you fix a broken stormwater pipe without digging up my yard?
In most cases, yes. Trenchless pipe relining lets us repair cracked, root-damaged, or leaking stormwater pipes by curing a resin-impregnated liner inside the existing pipe, forming a new structural pipe in place. No trenches, no garden disruption, no lifted pavers or driveways. It’s usually faster than excavation and significantly cheaper once you account for reinstating surfaces. Where a pipe has fully collapsed or the installation itself is non-compliant, targeted excavation may still be necessary, and we’ll tell you that upfront rather than promise a reline that won’t hold.
Q: What's your warranty on stormwater work?
All our workmanship is covered by our Lifetime Workmanship Guarantee. If anything we’ve installed or repaired fails because of how we did the work, we come back and fix it at no charge, for as long as you own the property. Materials are covered by their manufacturer warranty on top of that.
Q: Can I pay off a large stormwater repair over time?
Yes – we’re partnered with Humm for flexible payment plans*, no deposit, and fast approval. That means a major stormwater repair or full system upgrade doesn’t need to wait for the next pay cycle. Our team walks you through the application when you book, so it’s sorted before work starts. Ask us about Humm when you call.
