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

City of Sydney 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 City of Sydney 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
Local questions

Blocked drain FAQs for Zetland

Why clear a Zetland blockage before CCTV?

Flow and visibility often need to be restored before the pipe condition can be assessed. City of Sydney also says blockages must be cleared before drainage problems are investigated.

What if several units are affected at once?

Notify the authorised building contact, compare units and levels, limit fixture use where safe and arrange assessment of the common service route.

Does CCTV determine strata ownership?

It can document the pipe and fault position, but strata plans and the lots served still determine whether the line is private or common property.
