The Infill Sewerage Program is a Western Australian Government initiative which we administer. It aims to provide sewerage connections to properties where the use of septic tanks poses a risk to public health and the environment.
Infill sewerage is a system of buried pipes that removes wastewater from residential properties for safe treatment and disposal.
Why are we doing it?
Nowadays, the installation of sewerage pipes usually happens when land is developed and before new homes are built. But many areas in WA developed between 1950 and 1975 used septic tanks and leach drains for wastewater disposal.
The Infill Sewerage Program aims to reduce the potential for health and environmental issues by capturing and treating wastewater in a modern and safe way. It also helps with the orderly modernisation and renewal of residential infrastructure.
How to connect
Once the central wastewater system is completed in your area, you will need to arrange for a licensed plumber to connect your property to the sewer connection point.
We encourage you to connect as soon as possible and you need to connect within 5 years. Find a licensed waterwise plumber.
If you have a septic tank, please contact the health services section of your local council to find out about decommissioning requirements.
How much will it cost?
The cost of connecting to the wastewater system ranges depending on individual property requirements, such as depth and length of wastewater pipes and ground conditions.
We encourage you to contact a licensed plumber to confirm an expected connection cost.
Sewerage rates will be charged once the system is operational and we have notified you in writing of its availability. These rates will be charged whether or not you have connected to the system.
Eligible pensioners can apply for concessional rates or for payments to be deferred. Find out more about concessions for pensioners.
The Infill Sewerage Program is one of the biggest single capital works programs undertaken in Western Australia and is an investment in public health and the protection of our environment.
The program started in 1994, but has been deferred several times due to budget constraints and higher priority water supply projects.
The Infill Sewerage Program has enabled approximately 93,000 households across Western Australia to access the central wastewater system.
