Soakage pits and slow-draining stormwater

Blocked Soakage Pit Auckland

When a soakage pit or soak hole stops draining, rainwater can sit in lawns, overflow from grates, or back up through private stormwater pipes.

Signs of a soakage problem

A blocked or overloaded soakage pit can be harder to spot than a blocked grate because the issue may be underground. The surface symptoms are usually slow draining, recurring pooling, or stormwater backing up after rain.

  • Water sits in the same lawn or driveway area after every storm.
  • Stormwater drains slowly even when grates are clear.
  • Catchpits fill and drain away slowly.
  • The problem is worse after long wet periods when ground is saturated.

What may need checking

A professional may inspect the upstream pipe, clean silt from pits, jet the line, or check whether the soakage system is blocked, undersized, or affected by saturated ground conditions.
