Rain and property protection

Stormwater trouble often appears during rain when pits overflow, downpipes back up or water sits around the driveway, yard or house.

Fast answer

Blocked pit, grate or stormwater pipe?

If a pit, grate or downpipe backs up during rain, the private stormwater drain may be blocked by leaves, silt, roots or damaged pipework. Start with the point that overflows, clear the connected line where possible and inspect it when the problem keeps returning.

Signs the stormwater line is restricted

  1. 01Pits or grates remain full after rain eases
  2. 02Water backs up at downpipe connections
  3. 03Surface water moves towards the building
  4. 04The same area pools during repeated rain events

Clearing stormwater

Clear the pit and connected line

Leaves and silt can be removed from accessible pits and grates. The connected pipe may then need jetting, with CCTV used when flow stays poor or the same area floods again.

How we clear the blockage

01
Pit and inlet clearing
When leaves, silt or debris restrict the collection point.
02
Stormwater jetting
When the connected pipe and access allow high-pressure flushing.
03
CCTV and locating
When the buried pipe, connection or problem location is unclear.

Before you book

Stormwater Drains questions

Straight answers about when this service helps, what is involved and what happens next.

View all drain questions
Why does my stormwater drain only block when it rains?

Heavy rain exposes partial restrictions. Leaf litter, silt, roots, or a low section can pass light water but fail once the system is under load.

Can stormwater drains be inspected with CCTV?

Yes. CCTV is useful when flooding keeps returning or when the line may be crushed, full of roots, or disconnected underground.

How do you tell a blockage from a stormwater capacity problem?

A blocked pit or pipe may stay slow after rain eases. Water that appears only during very heavy rain can also involve surface flow or more water than the system can carry, so the pits and pipes need checking.

Who handles a blocked stormwater drain?

Property owners generally arrange work on private stormwater drains, while councils manage relevant public drains. The next call depends on where the blockage is found.

What should I note before calling about stormwater flooding?

Record which pit, grate or downpipe connection fills first, whether water enters the building, how it changes after rain eases and any safe access points you can see.
