Drainage Services in Riverwood
1000+ five-star reviews
Drainage is where a Riverwood home first betrays its years. Many streets were set out when the suburb rose on the old wartime hospital land by the station, and the sewer and stormwater lines beneath those blocks have carried flow for well over half a century.
Our drainage plumbers handle the full picture, from a gully that empties slowly outside a post-war cottage to a collapsed main under the front lawn. Call (02) 9072 0592 and a licensed plumber, not an answering machine, will talk it through before anyone books a truck.

When to Call a Drainage Plumber
Some drainage trouble can wait a day, and some cannot. A sewer surfacing through a downstairs gully or a storm drain surcharging against the slab needs a plumber on the phone now, so use these signs to point yourself at the right fix.
Wastewater rising in the yard or shower. When grey water or worse pushes up at the lowest fixture, the line downstream is choked, and that is a blocked drain or a deeper blocked sewer that needs clearing before it spreads through the house.
Gurgling toilets and slow tubs together. Air pulling back through several fixtures at once points past a single trap to the shared main run, and that pattern is the kind of fault a drain camera locates fastest.
Water pooling long after heavy rain. Grates that overflow and puddles that sit against the footings mean the stormwater drainage is blocked or undersized, not simply a wet week that will dry out on its own.
The same drain blocking again and again. A line that clears then re-blocks within weeks is telling you the pipe itself is cracked or root-bound, which is a repair question rather than a case for yet another routine clean.
A rotten or damp smell near a gully or wall. Sewer odour drifting up outside or a persistent damp patch can flag a broken pipe leaking underground, well before anything visibly backs up inside the home.

The Clay Sewers Beneath Riverwood
The signature drainage fault in this suburb is the vitrified clay sewer. Post-war cottages here were plumbed in short clay lengths joined every metre or so, and after decades in the ground those joints are where the trouble reliably starts.
Two local conditions work on them without a break:
- Reactive clay and shale The ground swells when wet and shrinks when dry, and that seasonal movement slowly offsets and cracks the rigid clay joints.
- Root-seeking moisture Every hairline crack weeps a little water, and roots follow it, prising the joint wider each season until flow begins to snag.
- Sheer age Clay laid in the 1950s and 1960s has already outlived its comfortable service life, so failures now cluster rather than arrive one at a time.
Once a joint has opened, cleaning alone is a short reprieve. The lasting answer is a trenchless pipe reline or a dug repair, and a camera survey is what tells us which one the pipe in front of us actually needs.

Every drainage job on the site routes back through the six services below. Each card explains what the work covers and when a Riverwood home tends to need it, then links you to the full page.
Start wherever your symptom fits, and the deeper detail on method, timing and what to expect lives one click on.
Drainage Repair & Installation
Cracked, sagging or root-split lengths of pipe are excavated and replaced, or a fresh line is run for a new bathroom or laundry. The ground is reinstated and the finished drain is pressure-checked before we hand it back.
- New drainage for extensions, granny flats and re-plumbed wet areas
- Point repairs where a single joint or section has collapsed
Blocked Drains
Sinks, floor wastes and yard gullies that drain slowly or back up entirely are cut clear with a high-pressure jetter. A camera then confirms the real cause, so the fix deals with the fault and not just the day's symptom.
- Kitchen, laundry, basin and floor-waste blockages
- Root mats and grease that keep coming back
Blocked Sewer
When wastewater surfaces at the lowest gully or the pan empties slowly, the sewer line itself is usually snagged on roots or a dropped joint. We clear the entire run from your boundary connection inward and check it is flowing freely.
- Overflowing gully traps and slow, gurgling toilets
- Whole-of-house backups after rain or root intrusion
Stormwater
Downpipes, surface grates and yard drains that overflow in heavy rain get cleared, repaired or upgraded. Run-off is directed to the street or the pit instead of banking up against the slab, footings and paths where it can do real damage.
- Overflowing pits and downpipes during storms
- Poor yard fall that pools water near the house
- Redirecting run-off away from the slab and foundations
CCTV Drain Inspections
A self-levelling camera travels the line to show precisely where a blockage, crack or root mass sits. You get recorded footage and a marked depth instead of guesswork, which is why we run one before opening any ground.
- Locating faults ahead of a repair or reline
- Pre-purchase drain checks on older homes
- Confirming a reline has cured cleanly end to end
Pipe Relining
Many broken drains are mended without a trench by curing a new resin liner inside the failing pipe. It seals split joints and locks roots out for decades, and your driveway, lawn and garden stay whole while it happens.
- Cracked and root-invaded clay sewers
- Repairs under paving, slabs and mature trees
Roots, Reactive Soil and Storm Run-Off
Beyond the clay joints, the setting of the suburb shapes what goes wrong underground. Salt Pan Creek Reserve wraps a bushland edge around the south, and the established street trees planted through the post-war blocks both send feeder roots hunting for the moisture inside ageing drains.
Water sits low toward the creek, too. The creek joins the Georges River right at the suburb's edge, and the flat ground by that junction keeps the water table high, so storms can surcharge the drains from below as well as above.
- Bushland-fringe roots Near the reserve and along tree-lined streets such as Bonds Road and Kentucky Road.
- Low-lying run-off On the flats near Gannons Park on the Peakhurst boundary, where heavy rain gathers fast.
- Seasonal joint movement As the reactive shale dries out and swells back through the year.
None of this is unusual for the older Georges River pockets. It simply means a drain here is working against roots, movement and water at the same time, which is why a proper diagnosis pays for itself.
How We Find the Blockage
Guesswork gets expensive, so any drain worth more than a plunger starts with a proper diagnosis and a clear decision path rather than a hopeful dig.
Camera first
Then clear it
Then choose the repair
This order matters because it separates a pipe that only needs cleaning from one that needs rebuilding. You are never paying to dig a trench that a liner could have avoided, or to reline a pipe that was only ever full of grease.
Drainage Warning Signs by Property Type
The stock around the suburb fails in different ways, so the signs worth watching depend on what you live in and how the drainage was built.
The post-war cottages
Walk-up flats and unit blocks
Renewed apartments and extended homes
Knowing which of these you own tells us where to point the camera first, and it usually explains why a drain has been misbehaving in the way it has.
Why a Slow Drain Is Worth Fixing Early
A drain that only gurgles today is rarely a drain that stays that way, and on reactive clay a small fault tends to widen with every wet-and-dry cycle the seasons put it through.
Small cracks become collapses
Water undermines what it sits under
Backups carry a health cost
Acting on the early signs keeps the job small, the mess contained, and the repair down to a single method rather than a staged rescue after the pipe has failed.
Storm Season and a High Water Table
The south of the suburb sits on ground the Salt Pan Creek flood study maps as low and flood-influenced, and that has real consequences for drains once the weather turns wet.
Run-off arrives from the higher streets
The water table pushes back
The lowest gully overflows first
Getting ahead of that means keeping the stormwater side clear and the sewer joints sealed, so a storm has somewhere to send its water other than up through your yard.
Keeping Your Drains Clear
A drain that has been properly cleared stays clear far longer with a little upkeep, and that is doubly true of the older clay lines carrying roots and movement.
Jet it, don't just rod it
Mind what goes down
Keep the stormwater side moving
A yearly camera look at a known problem line is quiet insurance, especially on a property with mature trees close to the sewer run.
After-Hours and Emergency Drainage
Not every drain waits for business hours. A sewer surcharging through the house or stormwater rising against the slab during a storm is a job for right now, not Monday.
We answer day or night
We make it safe first
If it is escalating fast, our emergency plumbing team runs the same trucks and the same warranty, so nothing changes except the hour on the clock.

Good questions, straight answers
Drainage Questions Riverwood Locals Ask
Why do tree roots keep blocking the older drains here?
The old street trees and the creek's bushland fringe push fine roots toward moisture, and the cracked joints in old clay sewer lines are exactly where that moisture escapes for them to find.
Can a cracked clay sewer be repaired without digging up the yard?
Usually yes, because a resin liner can be cured inside the existing pipe to seal split joints and lock roots out, so paths, driveways and garden beds stay untouched above it.
My yard drains overflow in every big storm, so what is wrong?
Homes on the low ground where the creek runs down to meet the river sit where run-off gathers, and overflowing grates usually mean a stormwater line that is blocked, broken or undersized.
How do you find a blockage without guessing where to dig?
A self-levelling camera is fed down the drain to show the exact fault and its depth on screen, so any repair is planned from recorded footage rather than trial holes dug across the lawn.
Is there a call-out fee to look at a blocked drain?
Looking at a blocked drain costs you nothing, and your plumber sets one fixed written price for the clearing or repair before any machine goes down the line.
Do you work on both the post-war cottages and the unit blocks near the station?
Yes, from the post-war cottages on the older streets through the estate walk-ups and the renewal apartments, we clear and repair drainage on every property type across the suburb.
