Local drain guidance

Blocked drain decisions in St Ives Chase

St Ives Chase had 998 occupied private dwellings in the 2021 Census, with separate houses accounting for 95.8%. This supports a private house-drain focus without making claims about an individual property’s pipes or access.

Council puts private stormwater maintenance with the owner but treats natural overland flow and groundwater seepage as different matters. A licensed assessment should follow the actual water source.

The next step depends on the evidence

  1. 01 · Clear

    Restore safe flow

    Clear the obstruction using a method suited to the accessible line and stop the immediate backup or overflow.

  2. 02 · Inspect

    Confirm the cause

    Use CCTV when the blockage repeats, the condition is uncertain or the fault position must be documented.

  3. 03 · Repair

    Fix a proven defect

    Recommend repair or relining only when the inspection, condition and blockage history support it.

Responsibility

Ku-ring-gai Council, Sydney Water or the property owner?

The responsible party depends on the affected pipe and fault position. Private drains are generally managed by the property owner, public wastewater faults by Sydney Water, and public stormwater questions by Ku-ring-gai Council.

  • Whether wastewater is actively overflowing or the drain is slow
