Vasse Diversion Drain Upgrade

The drain will be widened to hold more water for flood protection.

Water Corporation is planning to upgrade the Vasse Diversion Drain to increase flood protection in Busselton. Floods have continued to affect the Busselton community since the drain was built in the 1920’s, and although we have been making smaller modifications to the Busselton drainage system to mitigate flooding, these options have now run out.

The Vasse Diversion Drain starts just North of the Busselton Golf Course (refer to map under Document Library) and extends for around 6.3 km north to the ocean at Geographe Bay. It diverts water from the Vasse & Sabina rivers to prevent them overflowing and flooding Busselton.

In November 2000, State Cabinet accepted a proposal from the Busselton Flood Management Steering Committee to ensure the Busselton community be protected from 1 in 100 year rainfall events. This plan included the construction of large compensating basins and reconstructing the banks of the Vasse Diversion Drain.

Since then, we have been working towards this goal, having completed the construction of three compensating basins and reviews of local drainage needs. We have now determined the essential next step is to increase the capacity of the Vasse Diversion Drain while reconstructing the levee banks.


Have your say

In December, we set up pop-up project information booths. We spoke to over 100 residents to better understand how people use the drain and any concerns they had about construction or eventual changes to the drain, before finalising our design and construction plan.

We listened to this community feedback and now have solutions and strategies to share with you. These can be found under the Document Library .

We shared this plan at our our pop-up project information booths on 22 -23 February 2020 and continued speaking with the community. We will be back with an update on our environmental management plans and the outcomes of our environmental approvals when they are finalised later this year.

  • Project planning with the community

    We set out to talk with the Busselton community face to face to make sure their concerns are addressed early.

    The project team set up information booths in Busselton on 30 November and 1 December at Bunnings and the Foreshore Markets. We spoke with over 100 Busselton locals over the weekend and received some valuable feedback. Many people shared their eagerness to see improvements in flood protection for Busselton and told us stories of previous flood events.

    People also shared with us their concerns about the project. Common concerns included:

    · Walking/Transport routes over and along the drain during construction

    People also shared with us their concerns about the project. Common concerns included:

    · Walking/Transport routes over and along the drain during construction

    · Construction impacts like dust, noise and vibrations on nearby homes

    · Environmental impacts

    · Aesthetics of the drain when construction is complete

    · Integrated management of drains and rivers

    We are now working through these concerns to ensure they are addressed in our engineering designs and construction plans. We’ll be back in touch in early 2020 with the outcomes.
