Stormwater in Perth is different — and that matters when it blocks
Most Australian cities pipe roof water to street drainage. Perth doesn’t. Our deep sandy soils soak water so well that the standard arrangement is entirely on-site: downpipes feed underground soakwells — perforated concrete or poly chambers — that release rain into the ground within your own boundary.
It’s an elegant system with one catch: every part of it is the owner’s to maintain, and almost nobody does until it fails. Leaves and roof grit wash into pipes, fine silt settles in the soakwell base, roots find the joints — and none of it shows a symptom in the dry months. Then the first real cold front of June arrives, the system meets more water in an hour than it saw all summer, and the courtyard becomes a pond.
What we clear, from grate to soakwell
We service the entire stormwater chain: gutter outlets and downpipe connections, underground stormwater lines, grated pits and channel drains, and the soakwells themselves. High-pressure jetting clears pipe runs of silt, leaf sludge and roots; silted soakwells get physically cleaned out so their soakage surfaces work again. Where a line keeps failing, the CCTV camera shows why — cracked pipe, root entry or a joint that ground movement has pulled apart, each fixable with a targeted repair.
The problems concentrate where geography stresses the system. In the Perth Hills around Kalamunda, steep falls move winter runoff fast and punish any undersized or leaf-blocked line. On the heavy clays of Gosnells, water that can’t soak away runs overland and finds the low point — often a doorway. And near the coast in Rockingham, high water tables leave soakwells standing in groundwater with nowhere to soak. Same symptom — water where it shouldn’t be — three different fixes.
Why blocked stormwater is worth taking seriously
Pooling rain feels harmless compared to a sewage backup, but the slow damage is real: saturated ground against footings, rising damp in brickwork, undermined paving, and the permanently moist soil zone that subterranean termites actively seek out. Insurers also take a keen interest in whether flooding “resulted from lack of maintenance” — a silted soakwell that hasn’t been touched in twenty years is exactly the finding that complicates a claim.
A pre-winter check is cheap insurance: downpipes flow-tested, pits and grates cleared, soakwell condition assessed, and an honest word on whether the system’s capacity matches your roof area — especially if extensions or new paving have added catchment since the soakwells went in.
Beat the front, not race it
The best time to clear stormwater drains in Perth is before the forecast turns purple. Book a stormwater check or clearing anywhere in the metro area — and if it’s already raining and already flooding, we do emergency call-outs too.
