Blocked Stormwater in Wahroonga

Wahroonga sits high enough that its stormwater system has to move a lot of water fast once a storm hits, and that puts real strain on ageing pipework. Here's what a typical callout looks like.

Surcharging pit clearing. A pit pushing water back out during rain gets cleared and checked for what's actually causing the backup.

Downpipe and gully clearing. Overflowing downpipes and gully traps get cleared of leaf litter, silt and debris so water moves through properly again.

Root and silt removal from ag lines. Agricultural drains and channel drains around the property get cleared of roots and built-up silt, and checked for any collapse underneath.

Post-storm assessment. After a major downpour, we check pits, grates and gullies across the property for damage that a smaller storm wouldn't have exposed.

Wahroonga's elevated position means rain runs off the higher ground fast, and the large roof areas and paved surfaces on many blocks send a lot of that water into the stormwater system all at once. Older pipework was never sized for how hard modern storms hit.

The heritage-listed Wahroonga Reservoir on Woonona Avenue marks how long this area has carried established water infrastructure. Separately, much of the housing here predates 1940, built mostly through the 1920s and 1930s, and stormwater pipe of that vintage runs to a smaller bore than anything laid since, so it silts up sooner.

Deciduous street trees add their own seasonal pressure too, dropping leaf litter into gutters and pits through autumn that a single storm can wash straight into an already narrow pipe. Once a pipe partially silts up, even a moderate downpour is enough to overload what's left of its capacity.

1. Fixed quote. The cost is agreed in writing before any work begins.
2. Find the blockage. We trace the pit, drain or ag line to locate exactly what's stopping the flow.
3. Clear it. Jetting or mechanical clearing removes silt, leaf litter or roots from the line.
4. Camera check. A camera pass confirms the line is flowing and flags anything needing repair.
5. Test under load. Water is sent through the system to check it now copes the way it should.
6. Tidy and warranty. The site is left tidy, backed by our lifetime labour warranty.

Storm damage rarely waits for a convenient hour, and that's exactly why we're set up to answer around the clock, not just during business hours.

We also carry the jetting gear and camera equipment to fix the problem properly on the first visit, all backed by a lifetime labour warranty.

A repeat-offender pit or gully gets flagged for a maintenance schedule rather than another one-off callout, so the same storm doesn't catch the property out twice.
