Stormwater That Won't Drain Away
Rain that should run off to the street can pool in the yard or lie against the house after a storm. A stormwater drain is a drain system that carries rain off roofs and paved areas. Sydney Water says that water often runs from the property's drains to a street gutter that the local council operates. Blockages in a sink, shower or toilet sit on the wastewater side, which our blocked drains service clears. A yard can hold water from below as well. Mosman Council says Mosman's sandstone bedrock is rarely more than 1 to 1.5 metres deep, so groundwater runs heavily through the soil above it. When that groundwater runs unusually high in dry weather, Mosman Council advises having a licensed plumber check that the stormwater system is in good working order.
Stormwater Drain Cleaning Across Sydney
Cleared Now Drain Plumbing clears blocked stormwater drains from the stormwater pit and grate to the underground line:
-
Blocked Stormwater Pipes
Get a quoteThe underground stormwater line is the buried pipe that carries water away from the downpipes. What's The Damage lists water pooling against the foundations or under the house, instead of reaching the stormwater drain, as a sign of blocked downpipes. A downpipe clear is a job of its own. What's The Damage's 2026 Sydney guide says a clear downpipe with water still not draining points to the underground stormwater line. That blockage is a job for a licensed plumber with a jetter or camera. A blocked stormwater pipe under the lawn leaves water lying for days after rain. A stormwater drain blocked at the pipe needs the line cleared, not just the grate lifted.
-
Stormwater Pits and Grates
Get a quoteWe lift the grate on a stormwater pit blocked with silt and debris, clear the pit, and jet the pipe running out of it. New, raised or re-grated pits are separate pit work.
What Blocks a Stormwater Drain?
What's The Damage names the outdoor causes: tree roots in older clay pipe joints, storm debris where surface drainage joins the line, and soil movement that cracks rigid pipes:
-
Roots and Cracked Lines
What's The Damage's Sydney guide calls root intrusion in older clay pipes extremely common in Sydney's established suburbs. Its national guide says roots chase moisture into the joints of old clay and earthenware pipes. The same guide says soil movement cracks rigid pipes.
-
Storm Debris
When heavy rain runs off roads and properties, Sydney Water says the run-off carries litter, sediment, grease, oil and metals. What's The Damage also lists storm debris, washing in where surface drainage joins the line, as an outdoor cause.
Our Process
Stormwater drain cleaning runs in five steps, camera first:
-
Call answered
A real person takes the call 24 hours and arranges Same Day Service. -
Camera in first
The CCTV drain camera goes in from the nearest pit or access point and locates the blockage and what caused it before any quote. -
Quote before work
The price comes in writing before anyone starts, on every job. -
Jet or eel
We locate and clear the line with the electric eel, a motorised cable that drives through the blockage, or the jet blaster, a jetter firing high-pressure water. The camera's finding picks the tool. -
Flow check
We jet and inspect, then run water through the line and send the camera through again to confirm the line drains. The work carries Quality Workmanship Guaranteed.
Common Stormwater Drain Problems We Fix
Mosman Council says owners keep their stormwater drainage in working order so it doesn't flood or damage their own property or the properties downhill. A stormwater blockage shows up in the ways below:
-
Water Pooling After Rain
When water still lies across the yard after rain, the stormwater line may be holding that water up. Water pooling against the house points the same way. Sydney Water notes that a puddle or pool left after heavy rain may not be a leak. Sydney Water says water that smells like wastewater may be a wastewater blockage. Our drain camera shows where the water is held up.
-
Incorrect Connections
Sydney Water's connections diagram marks a roof downpipe joined to the wastewater system as an incorrect connection. In very heavy rain, stormwater pipes connected straight to the wastewater system let extra water into it. Correcting it takes new pipework, because the roof water needs its own stormwater line, which stormwater drainage installation covers.
-
Repeat Stormwater Blockages
Ask for a camera run when the same line blocks again after a routine clear. What's The Damage says repeat blockages point to a camera inspection and jetting. According to What's The Damage, the camera can find a collapsed section, a cracked pipe or a root-crushed joint. That work becomes stormwater repairs, quoted by length, depth and access.

Frequently Asked Questions
Who Is Responsible for a Blocked Stormwater Drain in Sydney?
In Mosman, the property owner is responsible for a blocked private stormwater drain, keeping the gutters, downpipes, pits and drainage pipes working up to the council's drainage system. Mosman Council looks after the stormwater system that drains the area beyond that. Mosman Council asks that blocked or damaged pipes causing flooding be reported straight away, through Mosman Council's stormwater page. Mosman Council can require owners to maintain their drainage under the Local Government Act 1993 and the Roads Act 1993.
How Do I Prevent a Blocked Stormwater Drain?
What's The Damage advises a periodic camera check where significant trees grow near the drainage run. The same publisher says habits solve indoor blockages, while outdoor ones come down to the pipe's condition. Our CCTV drain camera shows that condition before any quote.
How Much Does It Cost to Clear a Blocked Stormwater Drain in Sydney?
A standard drain clear in Sydney costs "$170 to $575" a job, $370 typical, with GST included (What's The Damage, October 2026). That guide gives stormwater lines no separate price, so these are general blocked-drain bands. What's The Damage puts a stubborn blockage needing a CCTV camera and high-pressure jetting at "$400 to $1,275", $805 typical, in the same October 2026 guide. According to What's The Damage's Sydney downpipe guide, an underground stormwater blockage that needs a drain machine or jetter costs more than clearing a downpipe. The call-out fee is $0, and the written quote fixes the price before work begins.
Can an Electric Eel Clear a Blocked Stormwater Drain?
Yes, an electric eel can clear a blocked stormwater drain as a standard clear that restores flow. The eel is a motorised cable that drives through the blockage. What's The Damage says mechanical tools only trim tree roots, while jetting cuts the roots back to the pipe wall. A line full of roots needs the jet blaster. Before the written quote, the camera shows which tool suits the line.
Can I Pour Drain Cleaner Into a Stormwater Drain?
No, drain cleaner doesn't belong in a stormwater drain, because in Mosman only rain may go into the stormwater system, and anything else is illegal and can be fined. Mosman Council also asks residents to compost or mulch garden and lawn clippings rather than wash garden sweepings into the stormwater system. Mosman Council says the area's stormwater ends up in Sydney Harbour. What's The Damage says caustic drain chemicals rarely fix a real blockage and won't touch tree roots.
How Do I Book a Blocked Stormwater Drain Clear in Sydney?
One call to (02) 9158 3577 books the clear, with a real person on the line 24 hours arranging Same Day Service. The call-out fee is $0.
