Tender released for the construction of a new water treatment plant in Busselton Monica Gameng | September 30, 2026 Security of Busselton’s drinking water supply is a step closer to reality, with the release of a tender to construct a new water treatment plant as part of the $59.1 million Busselton Water Supply Improvement project.

The project is jointly funded by the Australian Government through the National Water Grid Fund and Western Australian Government.

“The Albanese Government is proud to partner with the Cook Government to invest in water infrastructure that will support Busselton’s growing community for decades to come.

“Through the National Water Grid Fund, we’re investing in practical projects that strengthen water security and help regional communities to prepare for future growth.

“This project will provide Busselton with a more resilient and sustainable drinking water supply, while supporting the homes, businesses and local economy that rely on secure water,” Federal Minister for the Environment and Water Murray Watt said.

In addition to the new water treatment plant, the project will also establish a new inland drinking water source supporting infrastructure, including two seven-megalitre treated water storage tanks that will help strengthen water supply reliability, a pump station and an expansion to the distribution network.

The project will enable 4,000 new connections to the community water supply and it supports the State Government’s efforts to increase housing supply in regional Western Australia.

The new treatment plant alongside inland bores will reduce reliance on Busselton Water’s coastal borefields and allow for sustainable development of inland groundwater resources.

Installation of the new production bore, and an associated monitoring bore are already complete.

“Busselton is growing, and we need to make sure the infrastructure that supports that growth keeps pace.

“Reliable water infrastructure is fundamental to growing our regional communities – it supports new housing, gives businesses confidence to invest and helps create local jobs,” WA Minister for the South West Don Punch said.

Tender submissions for the construction of the new water treatment plant will close on 4 December 2026.

Once appointed, the successful contractor will finalise the detailed design and build the new water treatment plant, including treated water storage tanks, pumping and electrical systems, controls and supporting infrastructure.

The contract to be awarded will also include testing and commissioning before the new facility is integrated into Busselton Water’s network.

Tenderers are encouraged to maximise opportunities for local contractors, suppliers, trades and services providers – ultimately supporting economic activity across the South West.

“This $60 million project is about securing Busselton’s drinking water supply for the long term, while supporting more homes, local jobs and continued economic growth.

“The project will also provide opportunities for South West contractors, suppliers and trades, keeping more of the economic benefit in the region.

“By developing a sustainable inland water source, we’re also reducing pressure on Busselton’s coastal borefields and building a more resilient water network for future generations,” WA Water Minister Daniel Pastorelli said.
