Quindalup - Dunsborough 5C and 9A

back to current projects

Project goal:

Complete infill sewerage works in this area


Commencing soon

Delivery Date:


This work will eliminate the need for septic tanks and leach drains and will allow 206 residential lots to connect to the central wastewater system.

As of July 2018, we are progressing the tender process and expect to finalise the work schedule and estimated connection dates once a contractor is appointed.

At this stage we expect construction work to begin in Quindalup in mid/late 2018.

We will be in touch with impacted property owners as the project nears a start date and will keep the community informed as work progresses.

Water Corporation will soon start work in Quindalup as part of the State Government’s Infill Sewerage Program. We’d like to know how you would like to be kept informed during the work by taking the survey below.

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 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. But, between 1950 and 1975 many areas were developed in WA using 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 renewal and modernisation of 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 will do their best to minimise any 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 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.

So far the program has enabled approximately 93,000 households across Western Australia to access the central wastewater system.
