What Happens When Adelaide's Stormwater Drains Block
A stormwater drain blocks when leaves, silt, roots or a broken pipe stop roof and driveway rainwater escaping, so gutters spill over mid-storm and yards flood. Toilets and sinks empty into a separate sewer line.
What we find on the job
Six Causes of Blocked Stormwater Drains
Rain washes roof and yard debris into the pipe, so why does the drain choke underground? Six causes explain it:
-
Leaves & Gutter Debris
Autumn leaves, twigs and roof grit wash off gutters into downpipes with every Adelaide downpour, compacting at bends and pit outlets into soggy plugs, forcing rainwater back up the pipe.
-
Tree Roots
Roots from gums, figs and jacarandas find hairline cracks in older clay stormwater pipes, then thicken inside the joint until a dense root mat catches leaves and silt, blocking flow.
-
Silt & Sand
Heavy rain carries soil, sand and mulch off garden beds and unsealed driveways into grated pits, where the sediment settles in low pipe sections and hardens into a solid layer.
-
Collapsed Pipes
Once shifting soil or sheer age cracks a stormwater line, the broken section sags or caves in, trapping debris at the break and leaving water nowhere to go but back.
-
Blocked Pits & Grates
Surface grates and silt pits are meant to catch debris before it enters the pipe, yet a pit left unemptied for years fills to its outlet and overflows across paving.
-
Poor Pipe Falls
Pipes laid with too little fall, or dipping where the ground settled, hold standing water in shallow bellies, and each storm drops fresh sediment there until the line barely drains.
Don't ignore these
Signs Your Stormwater Drain Is Blocked
Walk the yard during the next heavy shower and these four signs point to a blocked stormwater drain:
Overflowing Gutters
Water spilling over the gutter while the downpipe stays quiet means rainwater cannot get down and away, pointing to a choked downpipe, an overfull pit or a blocked underground line.
Pooling Water
Puddles that linger around grates, paths and driveways for hours after rain has stopped tell you the stormwater system is draining too slowly to cope with the next Adelaide storm.
Soggy Lawns
Spongy, waterlogged patches of lawn above the stormwater route, often greener than surrounding grass, suggest a cracked or blocked pipe is leaking underground instead of carrying rainwater to the street.
Water Near Foundations
Rainwater collecting against the house after storms is the sign to act on fastest, because water sitting beside footings can soak into subfloors and walls and cause damp problems indoors.
No surprises, start to finish
How Our Plumbers Work
Found, Cleared and Flow-Tested
Clearing a blocked stormwater drain takes five steps, whether the job is in Mawson Lakes or Blackwood:
- 1
Rapid Inspection
Arriving promptly anywhere in Adelaide, our plumber walks the gutters, downpipes and pits with you, noting exactly where water overflows first to trace the blockage back toward its likely source.
- 2
CCTV Diagnosis
Feeding a camera down the affected line confirms whether leaves, roots, silt or a collapse is to blame, which decides the right clearing method before any machine is set up. Our CCTV drain inspection records the footage, so you get an answer before any digging.
- 3
Fixed Upfront Quote
With the cause confirmed, you receive a written fixed price for the whole job, because we charge by the job, not the hour, and nothing starts until you approve it.
- 4
Clear the Line
Our jetter works through the affected line from the nearest access point, flushing leaves, silt and fine roots, while each pit is emptied and each downpipe cleared, so everything drains. Hydro jet cleaning scrubs the pipe wall clean instead of punching a hole through the plug.
- 5
Test the Flow
Hosing water through gutters, downpipes and pits after the clear proves rainwater reaches the street kerb or council connection freely, and a final camera pass confirms nothing was left behind. Where the camera shows a collapsed or root-riddled section beyond cleaning, our drain replacement team replaces the damaged length so the fix holds.
Local knowledge
Who Is Responsible for Adelaide Stormwater Drains
SA Water says street stormwater drains are your local council's responsibility, not its own, and here's what that means:
Council Street Drains
According to SA Water, stormwater is rainwater running off roads, driveways, footpaths and rooftops into street gutters, and the drains it then enters are the responsibility of your local council.
Your Property's System
Gutters, downpipes, pits and pipes carrying rainwater across your own land to the street are where a licensed plumber works, and our plumbers at Exceed Plumbing clear exactly that section.

Straight answers
Blocked Stormwater Drains Adelaide Frequently Asked Questions
Here are straight answers to the stormwater drain questions Adelaide homeowners ask us most often:
What causes a blocked stormwater drain?+
Leaves, gutter debris, silt, tree roots and collapsed or badly graded pipes cause most blocked stormwater drains, and they build up gradually until one heavy downpour exposes the problem through overflowing gutters and pits.
Who is responsible for stormwater drains in Adelaide?+
According to SA Water, local councils are responsible for Adelaide's street stormwater drains and SA Water doesn't maintain them, while gutters, downpipes, pits and pipes on your own property are where a licensed plumber works.
How do you unblock a stormwater drain?+
We unblock a stormwater drain by locating the blockage with a CCTV camera, hydro jetting silt, leaves and roots off the pipe walls, emptying pits, then flow-testing every downpipe to confirm water drains freely.
Can tree roots block stormwater pipes?+
Yes, roots enter stormwater pipes through cracked joints and form mats that trap leaves and silt, so we cut thick roots with a cable machine, jet the walls clean, then camera-check for damage.
What happens if a stormwater drain stays blocked?+
A stormwater drain left blocked keeps overflowing whenever heavy rain hits Adelaide, so water pools against footings, soaks garden beds and paths, and the trapped sediment and roots make the eventual clear a bigger job.
Do you clear blocked stormwater drains across Adelaide?+
Yes, our licensed plumbers at Exceed Plumbing clear blocked stormwater drains across Adelaide metro and the Adelaide Hills, 24/7, with same-day service, fixed upfront pricing and a lifetime labour warranty on every job.
