Stormwater and Drainage Plumbers for Commercial Sites

Blocked drains, silted pits, burst mains and stormwater that ends up inside the building. We find the cause with a camera, clear it with our own jetting and vac trucks, and fix it to AS/NZS 3500.

Who owns the pipe and where council picks it up

Private stormwater lines belong to the owner up to the legal point of discharge. Not every pipe crossing your title is yours, though. Easements, council mains and shared strata lines muddy it, and we establish which side of the boundary the fault sits on before quoting a dig.

What we cover and who we work for

We design, repair and maintain stormwater and sewer drainage on commercial and institutional sites across Gold Coast, Brisbane, Moreton Bay and the Sunshine Coast. Most calls come from facilities managers at schools, shopping centres and universities, and from body corporates with older strata stock. That covers pits, pipes, soakwells, detention systems and the compliance paperwork that goes with them.

Water pushing out from under a driveway in heavy rain

The line has failed somewhere below, and the water is finding its own path out. Driveways get undermined that way.

Bubbling at the base of a downpipe

The pit or the line under it can no longer take the flow, so the downpipe backs up.

Ground near the carpark edge staying soft for weeks

Water is sitting in the fill and not moving. Subsidence and slab edge movement follow.

A pit holding water for days after a storm

Silt or a collapse downstream. The pit has lost its outlet.

Each one points to a different fault. A soakwell copes with light showers but saturates. Detention handles peak flow. Clay and terracotta lines fail first at the joints. The camera tells us which one you have.

Who we work with

Some of the organisations that keep us on their approved lists.

Stormwater drainage services we provide

Heavy subtropical rainfall in South East Queensland puts immense pressure on residential and commercial drainage infrastructure. When water lines leak or stormwater channels become clogged, pooled runoff can quickly threaten your property’s structural integrity. Affinity Plumbing Solutions delivers complete water and drainage care, ensuring efficient flow and total protection for your site year-round.

Pit and drain cleanouts
The vac truck sucks silt, leaves and debris out of stormwater pits, then we jet the line so it actually drains next storm.
Blocked drain clearing and jetting

Our own commercial jetting units for 100 mm lines and larger. Eel for the small stuff.

Pipe repair and replacement

Sewer and stormwater lines, with the surface reinstated afterwards.

Soakwell and on-site detention
Designed and sized from your roof and hardstand area, then installed.
CCTV inspection and drain locating.

Depth marked on the surface and a BYDA lodged before any excavation.

Burst water mains
Isolation first, then repair. If the floor has no isolation valve we add one while it is open.

Repair and handover

Work to AS/NZS 3500, surface reinstated, Job Safety Analysis and pipework map issued with the invoice.

Not sure what's under your carpark?

Book a camera run. Half a day for most sites, and you get the footage, the map and a price for anything it finds.

Frequently asked questions

Stormwater sits shallow. A line 1.5 to 2 metres down is almost certainly sewer. If you are not sure, a quick locate settles it.

It must sit above the surrounding ground with a loose grate so a sewer surcharge comes out there and not inside the building.

Council holds the record and usually charges for the location. Older properties sometimes discharge to a barrel drain, a rubble pit or a neighbour's line, which is where problems start.

Often, where the host pipe is intact and there is access at both ends. A collapsed section still needs digging.

Twice a year, either side of the wet season, with extra jetting for carparks and kitchen surrounds.

That their QBCC licence covers drainage, and whether they own their camera and jetting gear or hire it in. Ours is QBCC 1258056 and the trucks are ours.
