About This Service
A stormwater pit collects water from the yard, paving or downpipes and sends it into the stormwater line. When the pit fills with silt, leaves or roots, or the line out of it blocks, the pit overflows and the water goes across the yard instead. In Rhodes, overflowing pits had been blocked by tree roots and debris: we cleared four stormwater pits and a grate by hand, ran a CCTV camera through the stormwater lines, then jet blasted all the stormwater lines on the property to clear the roots. That's the usual order: clean the pit, see what's in the line, then clear it. Where water pools with nowhere to go, we install new pits and grated drains and connect them into the stormwater. You get a fixed price before we start, and 12 months on our workmanship.

(02) 9139 8945 — available 24/7Why Stormwater Pits Overflow
The pit is full
Silt, soil, mulch and leaves settle in the bottom of the pit until there's no room left and the outlet is covered.
The line out of the pit is blocked
Tree roots get into the joints of older stormwater pipe, and silt builds up behind them. The pit fills because the water can't leave it. That's what we found in Rhodes.
The grate is blocked on top
Leaves and grass clippings mat over the grate, so water runs past the pit instead of into it.
Too few pits, or in the wrong place
If water pools in a part of the yard with no pit, the problem isn't a blockage. It needs a new pit where the water actually collects.
Installing New Pits and Grated Drains
Where the water collects
A new pit goes at the low point where water pools, and is connected into the existing stormwater line, or a new line laid with fall to the discharge point.
The right grate
A grate in a lawn or garden is different from one in a driveway, which has to take the weight of a car.
Strip drains across paving
Along a patio, outdoor area or the bottom of a driveway, a grated strip drain catches water across its whole width. In Haberfield we installed grated strip drains along a new outdoor area to stop it flooding.
Kept out of the sewer
Stormwater and sewer are separate systems. New pits connect to the stormwater, never the sewer.
Looking After Your Pits
Check after storms
Lift the grate and look. If there's silt or leaves near the outlet, scoop them out.
Keep soil and mulch away
Garden beds that wash into a pit fill it quickly. A border or a step in the level helps.
Don't hose debris into it
Washing leaves and soil off paving into the pit sends them straight into the line.
If it refills quickly, call us
A pit that's full again soon after you've cleaned it usually means the line out of it is blocked.

Common Questions
FAQs
Why does my stormwater pit keep overflowing?
Usually the pit is full of silt and leaves, or the line out of it is blocked, often by tree roots. We clear the pit, put a camera through the line and jet blast it clear.
Can you clean out my stormwater pit?
Yes. We clear pits and grates by hand, and clear the stormwater lines behind them with the jet blaster.
Do you install new stormwater pits?
Yes. We install new pits and grated strip drains where water collects, connected into the stormwater.
Can tree roots get into stormwater pits and pipes?
Yes. Roots get into the joints of older stormwater pipe. In Rhodes we cleared roots from the pits by hand and from the lines with the jet blaster.
Can I clean the pit myself?
You can scoop silt and leaves out of the pit itself. If it fills again quickly or the water still won't drain, the line needs clearing.
How much does it cost?
We give you a fixed price before we start, with a $0 call-out fee.
