Network Repairs Program

Essential ongoing maintenance

Our water network handles billions of litres of water every year. We regularly check our wastewater system for damage using CCTV. When we find cracked, collapsed or damaged sections, we may need to dig to repair them. We replace aged and damaged wastewater pipes, valves and maintenance holes to improve the wastewater system in all areas of Greater Sydney.


Overview

Our wastewater system includes a network of over 25,000 kilometres of pipes. These range from 100mm to 900mm in diameter.

The system also includes structures like maintenance holes, lamp holes, junctions and reflux valves.

This large network of wastewater pipes and structures is underground, beneath roads, backyards and buildings. It is subjected to ground movement, root invasion and vibration, which ultimately take their toll.

We regularly check our wastewater system for damage using CCTV. When we find cracked, collapsed or damaged sections, we may need to dig to repair them.

We complete thousands of jobs to repair our wastewater network throughout Sydney, the Illawarra and the Blue Mountains every year. These repairs keep our wastewater system operating effectively and help protect the environment and public health.

We repair wastewater pipes affected by ground movement, tree roots and vibration.


Project stages

When working on private property, our contractor will prepare a home plan with the property owner or resident as a first step.

A home plan is a written agreement between our contractor and the property owner or resident that is put in place before any work starts.

 It outlines:

  • what the work is
  • how long the work should take
  • how the work will be done
  • which specific property details the owner or resident wants to be taken into account while the work is being done, for example if we need to be aware of children or pets on the property, or special garden features
  • how the property will be restored.

After the home plan is done, the work usually takes a few days. However, it may take longer if the job is more complex. The work involves:

  • digging and excavating an area to expose the damaged wastewater pipe or structure
  • replacing or repairing the damaged infrastructure
  • restoring the site to its existing condition.

After we finish restoring the site, we'll ask the property owner or resident to sign the home plan to say that the work has been completed as previously agreed.
