Plumber feeding a drain camera into a pit at a commercial unit

What stops a yard line draining?

Stormwater carries whatever the rain washes off your roof and garden, so it blocks differently to a sewer:

Leaf litter and bark from mature trees, washed down downpipes until it mats at the first bend or pit
Silt washed in from garden beds and unpaved ground, settling wherever the fall has flattened out
Roots finding a cracked joint, since a wet stormwater line is the easiest water source in a dry spell
A dropped section of the older clay runs, which holds water and debris instead of carrying it past

Any of those leaves water sitting in the yard hours after the rain has stopped.

Is it the stormwater or the sewer?

Stormwater and sewer problems announce themselves differently, and the signs point to the right one:

Stormwater faults follow the rain: the yard floods, the driveway runs, the gully at the low point of the block overflows, and it drains away once the downpour passes
Sewer faults show inside: the shower or floor waste backs up, the toilet gurgles, and the weather makes no difference
Water coming up in a shower while the yard is under water can mean both lines are involved, and a camera sorts which is which before anything is charged

When the problem turns out to be sewer-side, the blocked sewer page covers that work, and both lines sit under the parent blocked drains hub.

From gully to clean line

Find the entry point

The nearest gully or inspection opening sets where the gear goes in, and on the deep skinny blocks of the old Park Forest Estate that point is not always where you expect it.

Wash, don't poke

The jetter strips silt, leaf mat and root mass off the pipe wall the full length of the run, and the water carries the debris out ahead of it.

Camera after the clear

CCTV drain inspection footage then shows whether the pipe is sound or a cracked joint needs fixing before the next storm finds it.

Fix what the footage shows

A clean line needs nothing more. A cracked section can be relined without digging, and a line full of roots gets the tree root removal treatment.

What shapes the quote

We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.

Three things move the figure:

What the line is made of Since the mid-century clay runs take a gentler approach than PVC, and the quote reflects the pipe the camera finds
Where the blockage sits Because a gully beside the driveway is a shorter job than a run buried behind a retaining wall on one of the sloping blocks
What the fix needs Since a jet and a flush costs far less than a reline, and the footage settles which one you are looking at before you commit

Where Kotara's runoff goes

The creek decides some outcomes

Area figures put average rainfall here around 1128mm a year, and most of it arrives in bursts that Styx Creek, straightened in concrete through the suburb, has to shift all at once. Council's 2023 flood study flagged Gregory Parade and Wallace Street for a closer look, which marks where the street network runs out of puff in a big storm.

A surcharged street side is not your pipe's fault

A private drain with nothing in it can still spill over while the council connection is full, and repeated clears will not change that. The camera run separates the two cases, and when the blockage is actually out in the street-side network, council drainage owns the fix rather than another clear of a pipe that was never blocked.

When We're Not the Right Call

Flooding that comes off the creek or the street network rather than your pipes is a council drainage matter, and the footage shows it plainly when that is the case. Water entering the house at speed is one for the emergency plumber line first.

What Customers Say

[The team] have done an outstanding job at my mother's rental property. The area they worked on was particularly challenging, as it retained water and had become extremely muddy and boggy… The transformation has been remarkable.

Questions from Kotara yards

Why does my Kotara yard flood even after the drains were cleared?

Styx Creek takes this suburb's runoff, and when a downpour fills the council network, water gets pushed back up private lines that have nothing in them. A camera run after a storm shows whether your pipe is blocked or simply spilling over because the street side is full, which changes what the fix should be.

Do the retaining walls on sloping blocks affect stormwater repairs?

They do. The undulating ground means many lines run under or behind stone and brick retaining walls, so access takes longer and the method matters more. The quote covers the work the slope demands rather than a flat-rate guess.

Can you stop leaves blocking the drains again?

Clearing removes the blockage, but mature trees drop leaf litter every autumn, and gutters feed it straight to the gully. A grate on the pit and gutter guards on the roof both cut the debris reaching the line, and we can quote either at the same visit.

Is a flooded yard an emergency?

Water entering the house or pooling against footings is worth acting on quickly, and we take those calls at any hour. A slow yard drain with nothing coming inside can wait for a booked visit, and we name which one yours is when you ring.
