The Infill Sewerage Program has enabled more than 95,000 households in metropolitan and regional areas of WA access to the central wastewater system.
What is the Infill Sewerage Program?
The infill sewerage program, which started in 1994, aims to reduce the potential for health and environmental issues by capturing and treating wastewater in a modern and safe way and also helps with the orderly modernisation and renewal of residential infrastructure.
Infill Sewerage Program priorities are determined by the Minister for Water in accordance with public health, environmental and development criteria and are dependent on State Government funding. However, a recent review of proposed projects identified higher costs of the schemes compared with original estimates and available State Government funding, so some works will not go ahead.
The program includes projects in the following regions:
- Bindoon STED (not proceeding)
- Esperance 15B
- Kukerin STED (not proceeding)

How do infill sewerage systems and STED schemes work?
Infill sewerage is a system of buried pipes that takes wastewater away from residential properties for safe treatment and disposal. Once a property is connected to the central wastewater system, septic tanks and leach drains can be decommissioned.
Septic Tank Effluent Disposal (STED) schemes take wastewater that has already been treated in household septic tanks through a pipeline system, which is then pumped to an evaporation and infiltration disposal pond for further treatment. A STED scheme will allow existing leach drains to be decommissioned.
How do I 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 near you.
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 usually ranges from $1,500 to $3,500. This is subject to individual property requirements, such as depth and length of wastewater pipes and ground conditions.
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.
