Clear, inspect or repair

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

The Hills Shire Council and Hornsby Shire 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 the relevant council for the address — The Hills Shire Council and Hornsby Shire Council.

Process and scope

What affects the work and price

  • Whether wastewater is actively overflowing or the drain is slow
  • The number of affected fixtures and where the nearest safe access is
  • Whether clearing is enough or CCTV and locating are needed
  • The pipe condition and repair evidence found after flow is restored
