Blocked Stormwater for Cherrybrook Homes

A blocked sewer line and a blocked stormwater line cause very different headaches, even though both involve water going where it shouldn't. Here's what falls under the stormwater side of the work:

1. Surcharging pits that overflow onto the lawn or driveway once heavy rain sets in.
2. Downpipes and roof gutters that back up and spill over at the join instead of running clear.
3. Gully traps that fill and overflow before a storm has even properly passed through.
4. A slow build-up of garden debris that narrows a line over the course of a season.
5. Ag pipes and channel drains clogged with soil, mulch or mud washed in after a downpour.
6. Yard flooding that traces back to a blocked or undersized stormwater connection rather than the rain itself.

Cherrybrook sits close to 185 metres above sea level, on a ridge that falls away toward the Berowra Valley. That elevation catches the brunt of summer thunderstorms rolling through this part of the Hills District.

On the bigger, landscaped blocks common here, that means a lot of paved driveway and roof area feeding into one stormwater connection. A short, intense downpour can push more water through that single line than it was ever sized for, and the system surcharges rather than drains away.

Purchase Road sits on ground like this, on the falling side of the ridge, where a pit clearing a storm easily last month can be overwhelmed again the next time a heavier one rolls through.

Our licence, #465156C, covers stormwater work the same way it covers any other drainage job under NSW rules. AS/NZS 3500 plumbing standards apply whether we're clearing a pit or repairing a cracked section underneath it.

Larger stormwater alterations, like adding a new pit or changing where a line discharges, can require council approval before work starts. Clearing an existing blocked pit or pipe doesn't need that step, and we'll always say plainly if a job crosses into the kind that does.

Storms don't wait for business hours, and neither do we. A real person answers around the clock, so a surcharging pit gets attended the same day, not whenever it suits a calendar.

Book a jet blast and the camera survey that goes with it costs nothing extra, so you see exactly what caused the overflow, not just that it's gone.

Older homeowners save a further 20% on the completed job, and looking at the problem never costs anything whether or not you go ahead with the work. Every stormwater callout here gets treated the same way.

A blocked pit is sometimes the first sign of a bigger issue, which is why CCTV drain inspection or blocked drain repair sometimes follows on the same visit. The same crew covers Thornleigh, Winston Hills and the rest of the Hills District, all on the same quoted-upfront basis.
