Drainage Hornsby Heights: Sewers, Stormwater and Everything Underground
1000+ five-star reviews
Everything below the lawn has a page in this silo. Blocked drains, blocked sewer lines, stormwater design, CCTV drain inspections, pipe relining and full drainage repair and installation: six services, one department, all delivered by a licensed plumber with a fixed written price before work starts.
This hub is where Hornsby Heights homeowners work out which one they need. The suburb makes drainage interesting in a way flatter suburbs never experience.
Three factors do the damage here. Post-war earthenware sewers, a national park boundary feeding roots into every cracked joint, and blocks shedding stormwater down steep drops to the creek gullies combine into a set of problems this silo exists to solve.

Which drainage service do you actually need?
Water not draining where it should? Start with blocked drains, the page for sinks, showers, floor wastes and any pipe running slower than it should.
Sewage involved? That is blocked sewer territory, and if it is surfacing right now, treat it as urgent.
Rain is the problem? Stormwater covers pits, downpipes, ag lines and the design work sloping blocks demand.
Want to see inside the pipe first? CCTV drain inspections put a camera down the line before anyone commits to a fix.
The pipe itself is failing? Pipe relining rebuilds cracked runs without excavation, and complete rebuilds and new runs live on the drainage repair and installation page.
Not sure which bucket your problem sits in? Ring (02) 9072 0504 and describe what is happening; a licensed plumber, not an answering machine, will tell you.

Earthenware mains under the plateau's shallow ground
The sewers laid for the 1950s-60s homes along the original subdivision roads are largely original earthenware, and after decades in shallow shale-over-sandstone ground they crack at the joints. Bushlands Avenue and Evans Road both run through that first build-out wave, and the blocks behind them back straight onto bushland.
- Original earthenware pipes Crack and displace in ground that shifts with every wet and dry season, opening joints wide enough for fine roots.
- The bush boundary feeds those joints constantly With gums along the national park edge pushing feeder roots into any gap a cracked joint offers.
- Shallow soil means shallow pipes So vehicle loads, garden edges and even heavy mulching over the run can worsen a joint that was already failing.
That is why this silo starts with a camera, not a guess: the fix differs completely between a root-choked joint, a displaced pipe and a collapsed section, and the price differs with it.
The drainage directory: six services, six pages
- Blocked drains: the everyday unblocking service for sinks, showers, laundries and floor wastes.
- Blocked sewer: the sewer-specific page for surcharging gully traps and slow-then-stopped mains.
- Stormwater: design, pits and dispersal for rain coming off the ridge.
- CCTV drain inspections: camera diagnosis before any dig or quote.
- Pipe relining: rebuild a cracked pipe from the inside, no excavation.
- Drainage repair and installation: collapsed sections replaced, new drainage designed and laid.
Storms, slopes and the 190-metre ridge
The second local factor is gravity. This suburb sits at around 190 metres elevation, noticeably cooler than coastal Sydney, and when a summer downpour hits, the water does not soak in; it races. Plateau-edge properties shed run-off hard toward the gullies, and older pits sized decades ago for lighter flows surcharge under the load.
- Downhill blocks cop concentrated flows That scour gardens and undermine paths where a stormwater run is undersized.
- The steep streets funnel water So a blocked pit halfway up a slope backs water into every yard below it.
- Bushfire season cuts the other way The same leafy canopy that feeds drain roots drops litter that packs into grates and pits ahead of the first big storm.
Houses here fail drainage in predictable seasonal patterns, and the fixes are engineering, not luck. That is the difference between a drain that works in a drizzle and one that survives the February storm.

How it works
How we diagnose a drainage fault
The path from symptom to fix follows the same sequence every time, because guessing underground is how people pay twice.
- 01
The camera goes down first
A CCTV drain inspection shows whether you are dealing with roots, a cracked joint, a displaced section or a collapse, and where exactly the fault sits.
- 02
Jetting clears what can be cleared
High-pressure water cuts through root mass and sludge, restoring flow and revealing whether the pipe behind the blockage is still structurally sound.
- 03
Then the honest fork in the road
A sound pipe that was simply blocked needs nothing more; a joint-cracked run is a pipe relining candidate; a collapsed section means excavation and a full rebuild, which is the repair-and-installation service.
The camera footage means you see the same evidence we do, and the fixed price that follows is priced against what the camera actually showed, not a worst-case allowance.

Good questions, straight answers
Questions Hornsby Heights locals ask about drainage
Do the original clay sewers in Hornsby Heights have to be dug up?
Not always, because pipe relining can rebuild a cracked earthenware main from the inside without excavating a driveway, garden or bush-backed block, and a CCTV inspection first tells us whether your run suits it.
How often should drains be inspected in a bushland-interface suburb?
For homes bordering the national park or running original earthenware sewers, a camera inspection every couple of years catches root intrusion at the joints before a total blockage backs up the bathroom.
Why does stormwater cause problems on a plateau suburb?
The suburb sits at around 190 metres elevation and sheds run-off down steep falls toward the creek gullies, so water arrives fast at downhill pits built generations ago for far gentler flows.
Is a blocked sewer an emergency?
When sewage is surfacing or a gully trap is surcharging, yes, treat it as urgent and call, because the post-war houses here mostly have one bathroom and no fallback while the main is out of action.
What does a CCTV drain inspection involve?
A small camera travels the pipe while we watch the vision live, locating roots, cracks, displaced joints and collapses, then you get the footage and a fixed written price for whichever fix the run actually needs.
Can you design new stormwater drainage for a sloping block?
Yes, we size pits, ag lines and dispersal runs to suit the steep blocks above the gullies, so water is engineered away from footings and gardens rather than left to scour its own path downhill.
