Stormwater & Drainage Solutions Brisbane Sites Rely On

Water finds the cheapest way off a site. When stormwater stops taking it, the damage turns up under the slab and across the carpark, not in the drain.

What we cover and who we work for

Affinity Plumbing Solutions designs, repairs and maintains stormwater drainage on commercial and institutional sites across South East Queensland. Most of the work comes through facilities managers at schools, universities and hotels, and through body corporates holding older strata stock.

Our commercial drainage solutions run from pits and pipes through to soakwells, detention systems and the compliance paperwork that follows the repair.

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 still holding water days after the storm

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

Our Trusted Partners

Here are some of the trusted partners and commercial clients we have worked alongside across Queensland.

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.

Pipe repair and replacement
Terracotta and vitrified clay fail at the joints first. Roots find the misalignment, the joint opens, and the line silts up behind it. Most stormwater drain repair work on older Brisbane building stock starts at a joint like that.
CCTV inspection and drain locating.
Sewer plans exist. Stormwater plans often don’t. Councils hand over hand-drawn sheets from the seventies that don’t match what’s in the ground, and half the pits on a refurbished site sit under paving. Our drain locating and CCTV work marks position and depth on the surface, with a BYDA lodged before any excavation.
Blockage clearing and jetting.
We run our own commercial jetting trucks, so the machine turns up when the job is booked, and nobody waits on a subcontractor’s diary. High-pressure water shifts silt, sediment and root mass out through the pit.
Soakwell and detention system design and installation.
A soakwell copes with a light shower and then gives up once the ground around it saturates. On commercial sites, that job usually falls to on-site detention, sized to hold peak flow and release it slowly. We handle the stormwater drainage installation for both, sized off the roof and hardstand area feeding them.

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.

Four reasons property owners choose our Brisbane drainage solutions

How we work

STEP 01

Site assessment.

Our stormwater plumber walks the site, finds the pits, and works out where the water is meant to go.

STEP 02

Camera and locate

CCTV down the line with depth marked on the surface. You keep the footage. Fixed written quote.

STEP 03

Proposed solution and scope

Scope, method, reinstatement and timing, with options where more than one compliant fix exists.

STEP 04

Repair and handover

Job Safety Analysis issued with the invoice, PO and job numbers on the paperwork, gas certification where required, next service date set.

Not sure what's under your carpark?

Send us the site address and a photo of the pit. We’ll tell you whether it needs a jetter or an excavator before we quote.

Water, Stormwater & Drainage FAQs

Properly managed drainage and water supply systems protect your property from structural damage, soil erosion, and severe flooding. Here are answers to common questions about keeping your water and stormwater lines compliant and flowing freely:

Depth. Stormwater sits shallow. A line 1.5 to 2 metres down is almost certainly sewer, and if someone has quoted a dig that deep on a job they've called stormwater, get the plans checked first.

No. The gully has to sit above the surrounding ground so stormwater can't get into the sewer, and the grate is loose by design so it lifts when the line surcharges. Bury it and the next sewer blockage comes up inside the building. Paving, turfing and resurfacing crews cover these constantly on school and aged care sites, and the first anyone knows about it is the callout.

Council holds it and will supply the location, usually for a fee. Plenty of older Brisbane properties have no kerb outlet at all and run into a barrel drain under the street, a rubble pit, or a neighbour's line. Queensland stormwater drainage regulations and council plumbing approvals both key off that point.

Sometimes. Relining needs a host pipe intact enough to hold the liner and access at both ends, and a collapsed section still gets dug.

Check the QBCC number covers drainage work and ask whether they own a camera or hire one. Ours is 125 8056. Our drainage specialists cover Brisbane, Ipswich, Logan, Moreton Bay, the Sunshine Coast and the Gold Coast.

Twice a year on most sites, scheduled either side of the wet season. Carparks and kitchen surrounds silt up faster and want a jetting run in between. Planned stormwater maintenance costs a fraction of the drainage repair services that follow a collapse.
