Understanding the issue

Start with the right diagnosis.

Where the blockage occurs matters. Private drains and Sydney Water network assets have different responsibilities, so it is worth establishing the likely fault location.

How we approach the work

A licensed drainer can investigate private drainage. If the problem appears to be in the Sydney Water network, contact Sydney Water and follow its reporting process.

Before you book

If several nearby properties are affected or wastewater continues overflowing when no water is used on site, contact Sydney Water on 13 20 90.

What helps us quote or plan

  • Your Sydney suburb and property type

  • Relevant photos or system details, if safe to provide

We will discuss the scope, access and availability before an appointment is confirmed. Any price or repair method depends on inspection and the agreed work.
