Regional Sewer Relining
Project goal:
To reline old wastewater pipes, protecting the local wastewater system, homes and environment.
Status:
In progress.
Delivery Date:
On-going.
What’s happening?
Sewer relining is an ongoing program to renew ageing wastewater pipes. This work is completed by our authorised contractors. Where possible, pipes are relined using trenchless technology.
This means we won’t need to dig anything up to replace the pipes, minimising the impact on the local community. Check out the tab ‘How does it work’ for more information..

How will this impact the community?
Work activities
Nearby residents may notice more activity in the area. Noise from generators and vehicles and temporary odour. Work will be approved in advance by your local government authority.
Generally, we will be in one area for no more than six days at a time as we progress work along the wastewater route. If required, traffic management will be in place to direct people around the work area.
Access to property
Contractors will be working in both verges and/or roads and may work in the boundary of private properties. If crews need access to your property, they will contact you to discuss the work and arrange entry. They will only need access to your back or front yard and will not need to enter your home.
During the work
If you experience any odour in your bathroom, flush your toilet and pour water down the floor drain. Where possible, please close all toilet covers during this period.
In the rare instance wastewater does overflow out of your toilet, please notify the relevant contractor immediately. The contractor will assess the issue, work with you to organise a clean-up and notify the Department of Health.
| HOW DOES IT WORK | |
|---|---|
Step 1 - Pipes are checked via CCTVTo determine exactly what we need to do to fix them. |
 |
Step 2 - Pipes are cleanedHigh pressure water is jetted through the pipes. It may cause some odour or on a rare occasion, spurting from your toilet. We therefore advise to keep the toilet lid down. If water does spurt out of the toilet, please contact the Interflow Project Manager immediately. |
 |
Step 3 - Pipes are relinedA new liner is installed inside the old pipe by a machine and forms a new pipe. |
 |
Step 4 - New pipe is connectedLateral lines (property connections) are reconnected to the new pipe and junctions are sealed to protect the new pipe. This opens the connection to provide access to the system. |
 |
Step 5 - Pipes are checkedThis ensures that the job has been done properly. If we find any issues, we'll come back and fix it. We may need to return to the area to repeat the above steps. |
