About Us

We are the principal supplier of water, wastewater and drainage services in Western Australia to hundreds of thousands of homes, businesses and farms, as well as providing bulk water to farms for irrigation.

Our services, projects and activities span over 2.6 million square kilometres. We have regional offices in Perth, Bunbury, Albany, Karratha, Geraldton, Northam and Kalgoorlie which allow our employees to provide a high level of professional expertise to customers. We have over 2,500 employees and participate in alliances to manage an asset base of over $15 billion in water supply, wastewater, drainage infrastructure and bulk water for irrigation. We are owned by the Western Australian Government and accountable to our sole shareholder, Minister for Water the Hon Dave Kelly MLA, for delivery of our services in a commercial manner. Most of our surplus is returned to the government as a dividend to contribute to the development of the state, with the remainder reinvested in capital works.

Are headworks and infrastructure contributions the same?
Yes, infrastructure contributions were previously referred to as headworks contributions. These are one-off charges, payable for works up to the connection point on a property that will increase the potential demand on existing water, wastewater or drainage schemes.
What is a standard Water Corporation connection?
A standard Water Corporation connection is a 20mm metered service.
Where can I view current bids and tenders?
You can view and apply for public bids/tenders using the bids/tenders transaction in our supplier portal. You can only view restricted bids in this transaction if you have been invited.
What is the supplier portal?
The supplier portal (or eProcurement) provides an easy platform for suppliers to transact with us in real time. Suppliers can lodge bids, enter claims for payment and OSH statistics, and much more.
How can I access the portal?
Access to the supplier portal is available via our website.
What is supplier registration?
Supplier registration lets us gather information to assess your suitability for our supplier base.
Does registering guarantee Water Corporation business?
No. Registration is not a guarantee of work, and is purely an expression of interest to conduct business with us. Successful registration ensures our suppliers are committed to our health, safety and environment requirements.
What happens when prequalification expires?
If your prequalification lapses, this could restrict your company’s ability to be engaged for future works. If you are currently engaged in works with us, this won’t impact your engagement but it’s advisable to maintain active prequalification status.
