Drainage in Charlestown
Blocked Stormwater Charlestown
When summer storms hit the ridge and runoff starts backing up instead of getting away, the pipe is the problem, not the weather. Blocked stormwater is a routine call for us in Charlestown, and it's one we clear properly with a quote up front.
Why stormwater backs up on this ridge
This suburb doesn't flood from a creek. At roughly 116 m on the ridgeline there's no riverine flood exposure, so the water risk is all about surface runoff and what the pipes beneath it can handle.
Paved ground where gardens used to be
Driveways, extensions and paved courtyards have replaced garden ground across the town centre, so intense runoff now hits stormwater pits that were sized for a much smaller suburb.
Reactive clay moves the pipes
The reactive clay and shale under this ridgeline swell when wet and shrink when dry, shifting shallow stormwater runs until the falls flatten and water pools instead of draining.
Summer storms do the damage
Around 1128 mm of rain falls in an average year, much of it on hot, stormy summer afternoons, and a partial choke that copes with drizzle fails completely in a downpour.
Old pipework gives up eventually
Housing from the postwar decades dominates here, and the earthenware runs buried under yards of that vintage crack, sag and silt up as they move past sixty years of service.
How to spot a blocked stormwater line
Stormwater trouble shows itself during and after rain, which is one advantage over a sewer blockage. Watch for these signs:
- Gullies overflowing or dribbling across the yard while it's still raining
- Puddles sitting on paving hours after the rain has stopped
- Water spilling back out of the eaves because the gutters can't discharge
- Damp patches tracking a line through the garden between pits
- Runoff pooling against the house instead of heading for the street
One sign points to a choke somewhere downstream. Two or more usually means the blockage has moved past the first pit, and we've traced them along full runs between properties, including on leafy blocks off Bulls Garden Road where the garden beds hide where the pipes actually sit.
How we clear a blocked stormwater line
- 1
Call and tell us
Ring (02) 4063 3450 and tell us what's going on in Charlestown. We'll ask a few quick questions so the right gear is on the truck the first time.
- 2
Quote before work
You get the price before anything starts. No call-out fee, no hourly surprises - you approve the quote or we shake hands and leave, no charge.
- 3
Clear and confirm
For stormwater, that means jetting silt and leaf litter out of the line, cutting roots where they've pushed in, then running water through to prove the falls carry again.

Backed, no questions asked
If something isn't up to standard afterwards, we come back and make it right, no questions asked. That's the standard every Charlestown job is held to.
What the fix involves
A camera run before any digging
A CCTV drain inspection walks the whole line and shows whether the choke is silt, leaf litter, roots or a squashed section, so the repair targets the fault instead of a hunch.
Jetting clears without a trench
High-pressure jetting strips the line clean from end to end, shifting silt and leaf litter and cutting back fine roots, which is why it clears what rods and garden hoses leave behind.
Roots cut back at the joint
Street trees from the postwar subdivisions have had decades to find pipe joints, so root intrusion gets cut and the entry point gets flagged for a closer look once the line is flowing.
Collapsed sections get their own quote
If the camera shows a cracked or squashed run rather than a simple choke, we price the replacement separately, so you decide on the dig-up with the full picture in front of you.
What a stormwater clear-out costs
The $0 call out means getting us to your door costs nothing, and you approve the price before a tool comes out. What the job involves depends on a few things:
- How deep the pits sit and how far apart they are
- Whether roots have entered the line and need cutting back
- Whether any section has collapsed and needs replacing rather than clearing
Most blockages are a clear-and-confirm job. Anything bigger gets its own quote, as above.
Stormwater, sewer or a general drain?
Roof and yard runoff travels a separate set of pipes to the sewer, so the fix differs too. Inside-the-house backups belong on our blocked drains page, toilets and laundry troughs rising point to blocked sewer, and both sit under the main drainage hub.
Stormwater clearing in the suburbs nearby
A blocked gully doesn't care which side of the boundary it sits on, so we cover the neighbouring suburbs on the same run:
Stormwater questions, straight answers
Why does the stormwater only block in heavy rain?
A partial blockage handles light rain but fails in a downpour. Silt, leaves and roots narrow the pipe over time until one heavy summer storm outruns what's left of the flow.
Will a hardware store snake fix it?
You might shift leaves near a gully, but a shop-bought snake won't reach a root mass or silt bed partway down the run, and forcing it can damage older pipe.
Is the blockage my problem or the council's?
Pipes and pits on your own block, including the runs taking roof and driveway runoff, are yours to maintain, while the street network sits with council. We'll tell you which side you're on.
Do you come out during a storm?
We attend in bad weather where the schedule allows, and the $0 call out costs nothing. If water is heading indoors, ring (02) 4063 3450 and we'll tell you what to do meanwhile.
Do you clear stormwater for shops and unit blocks?
Yes. Paved carparks and courtyards around the town centre shed heavy runoff, and we clear pits and lines for strata managers and commercial tenants as well as houses.
How do I stop it happening again?
Keep gutters and gully grates clear of leaves, note where trees sit over shallow runs, and book a camera inspection if the same section slows twice. Fixing the cause beats repeat clear-outs.
