Connecting WA households to the central wastewater system.

back to current projects

Project goal:

The Infill Sewerage Program has enabled more than 95,000 households in metropolitan and regional areas of WA access to the central wastewater system.

Status:

In construction

Delivery Date:

Ongoing

What’s happening?

The Infill Sewerage Program is connecting households to the central wastewater system to avoid the health and environmental issues that come with septic tanks. We’re modernising and renewing infrastructure to ensure the safe, reliable removal of wastewater for residents.

Where is this happening?

Work areas are determined by the Minister for Water based on criteria like public health, and are dependent on State Government funding. See the table below for upcoming project areas.

Perth region

  • City Beach 2A (complete)
  • City Beach 2B (complete)
  • Halls Head 59A (complete)

Mid West

  • Bindoon STED (not proceeding)

Goldfields & Agricultural

South West

Great Southern

  • Esperance 15B (complete)
  • Kukerin STED (not proceeding)

Why is this work taking place?

This work ensures the safety and reliability of wastewater removal. It also eliminates the need for septic tanks, which can be hazardous to public health.

When is this happening?

Please view the specific project pages to see dates and timings.

How will this impact the community?

Once work is complete in your area, you’ll need to arrange a licensed plumber to connect your property to the sewer connection point. There are connection costs which range depending on individual property requirements, and we encourage you to confirm an expected connection cost with your plumber. Find a licensed Waterwise Plumber near you.

Sewerage rates will be charged once the system is available and we have notified you in writing. These rates will be charged whether or not you have connected to the system. We encourage you to connect as soon as possible and you need to connect within 5 years.

If you have a septic tank, you’ll need to contact the health services section of your local council to find out about decommissioning requirements.

If you have a Pensioner Concession, State Concession, WA Senior or Commonwealth Senior Health Card, you may be eligible for rebates or concessions. Find out more about pensioner and concession discounts.

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 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. If you have a Pensioner Concession, State Concession, WA Senior or Commonwealth Senior Health Card, you may be eligible for rebates or concessions.
