Stormwater Drain

1 min read Updated 6 Jul 2026 DrainSpy Brisbane
In short The separate piped system that carries rainwater from roofs, paving and land to street drainage, creeks or soakage — never into the sewer.

Australian properties run two independent drainage systems: sanitary (sewer) and stormwater. Stormwater collects from downpipes, surface pits and paved areas, discharging to the street kerb, an underground council network or approved on-site soakage.

Illegal cross-connections — stormwater into sewer or vice versa — cause sewer overflows in rain and contaminate waterways, and are a standard check during drainage inspections.

What Is It For?

Removes rainwater safely without loading the sewer system.

Where You'll Find It

From every downpipe and surface pit, running to street or soakage disposal.

Common Problems

  • Blockages from leaves, silt and garden debris
  • Roots in older stormwater lines
  • Cross-connections with the sewer system
  • Undersized old systems flooding in storms

How DrainSpy Brisbane Deals With It

A CCTV drain inspection is the standard way to confirm whether this is what's happening in your pipes: the camera shows the condition on screen, a locator pinpoints the exact position and depth, and you get a recorded report before any repair decisions are made.
