Plateau Plumbing designs, installs and services septic systems right across the Northern Rivers, and we bring our own excavator. General plumbing, gas, water tanks and roofing too. One bloke who answers his phone, and does the job properly.
Plateau Plumbing has been working across the Northern Rivers since 2017. Wardell, Bexhill, Brooklet, Alstonville, Ballina, and every dirt road in between. Most of it is septic work, because most plumbers would rather not touch it.
The advantage of doing the plumbing and the excavation yourself is simple: nobody is waiting on anybody. The trench gets dug, the tank goes in, the lines get run, and the ground gets put back the way it was found. One quote, one crew, one person to ring if something is not right.
Design, approval drawings, installation, and servicing. Tanks, reed beds, ETA trenches, pump-outs and flood replacements. If your system failed in the floods or it has quietly stopped coping, it is worth getting looked at before it becomes a bigger job than it needs to be.
Soil and site assessed, system sized to the house and the block, drawings prepared for council so the approval goes through without a back and forth.
Our own machine on site, so the dig and the plumbing happen together. Tank set, reed beds and trenches laid, ground backfilled and levelled properly.
Existing systems inspected, pumps and lines repaired, flood-damaged tanks replaced. Regular servicing so a small problem stays a small problem.



New systems designed, approved and installed end to end.
Certified gas installation, appliance connection and repairs.
Leaks, taps, toilets, hot water and drains that have stopped draining.
Full rough-in and fit-off for new builds, extensions and bathrooms.
Tanks supplied, set, plumbed and pumped for rural properties.
Our own excavator for trenching, site prep, pads and drainage.
Rural driveways formed, gravelled and drained to last a wet season.
Re-roofs, repairs, gutters and downpipes done watertight.
Built in the shed, one at a time, out of rustic pipe work and solid brass fittings. Designed for outside, where a shower actually earns its keep.
