Driveway channels and garage flooding

Driveway Drain Blocked Auckland

Blocked channel drains and driveway grates can send stormwater straight toward a garage, basement, entry, or neighbouring property during heavy rain.

Why driveway drains block

Driveway drains sit where leaves, mulch, tyre grit, sediment, and garden waste naturally collect. Once the grate or channel is covered, water runs over the top instead of entering the stormwater system.

What to check before calling

  • Keep people away from moving water and slippery concrete.
  • Take photos of the water level and where the water is flowing.
  • If safe, clear loose leaves from the grate surface.
  • Call for help if water is entering a garage, house, or electrical area.

If the surface is clear but water still will not drain, the channel outlet, catchpit, or stormwater pipe may be blocked deeper in the system.

The outlet and downstream stormwater pipe may be suitable for jetting depending on access and condition.
