Infill sewerage is a system of buried pipes that takes wastewater away from residential properties for safe treatment and disposal.
Why are we doing it?
Nowadays, sewerage pipes are usually installed as land is developed and before new homes are built. However, many areas in Western Australia 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.
What will happen in your area?
We will write to you before any infill sewerage works begin in your area and we will keep you informed throughout the project.
Installing a wastewater system can be disruptive as it involves digging large trenches to lay the sewerage pipes. There may be some temporary inconvenience with access to your property and possible road detours.
Contractors do their best to minimise noise, dust and access restrictions, but we ask for your patience and understanding while work progresses.
If we need to work within your property we will do our best to restore it as near as practicable to its original condition.
There is no cost to the landowner for making access to our central wastewater system available and there should be no disruption to water, gas, electrical or telephone services.
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 five 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.
So far the program has enabled approximately 93,000 households across Western Australia to access the central wastewater system.
