What is the Infill Sewerage Program?
In today's development era, sewerage pipes are usually installed as land is prepared for new housing developments. However, between 1950 and 1975, many areas in Western Australia were developed using septic tanks and leach drains for wastewater disposal.
The Infill Sewerage Program aims to reduce potential health and environmental issues associated with septic tanks and leach drains by providing these households with a connection to the central wastewater system.
What will happen in your area?
We will write to you before any infill sewerage work begins in your area and 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.
There is no cost to the landowner for making access to the 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 5 years. Find a licensed waterwise plumber.
If you have a septic tank, please contact the environmental health department of your local council to find out about decommissioning requirements.
How much will it cost?
For a residential property, 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.
Sewerage charges are based on your property’s Gross Rental Value (GRV) which is supplied by the Valuer General. The charge is calculated by multiplying a rate (cents in the dollar) by the GRV. The rates are different for each town or area as the cost of providing sewerage services varies for each country town sewerage scheme. A cap applies to residential sewerage charges in country areas and this cap is reviewed yearly.
Eligible pensioners can apply for concessional rates or for payments to be deferred. Find out more about concessions for pensioners.
