Every day, we supply South West Victoria with sustainable water services, while leading our communities towards a healthier, more prosperous future. It’s a commitment that we’re proud to make to the region we call home.

We’re your local, dependable experts

From the South Australian border to the Otways. From the Grampians to the coast. Our services take care of more than 30 communities, including residents, farmers, businesses and industries. It’s our responsibility to supply you with fresh water, from source to tap, and manage sewage to protect your health and wellbeing.

Putting people first comes naturally to us so we’re here to help with more affordable, reliable and personalised service. You’ll see us around, in towns and on streets, maintaining and upgrading the pipes, pump stations and treatment plants we all need.

We’re making a real and positive difference

As locals, we’re driven to shape our region for the better. We’re committed to working with our communities and strategic partners to support the health and wellbeing of our people and protect our natural environment. We simply believe it’s the right thing to do and it all comes back to our greater vision to go beyond water for stronger communities.

It’s about delivering sustainable water services together with positive change for our region – and we’re proud to be leading the way.

Our region

Our service area extends from the Otway Ranges to the South Australian border. It includes the major centres of Warrnambool, Portland and Hamilton and features the diverse landscapes of the Great Ocean Road, the Grampians, the volcanic plains and the Budj Bim National Heritage Landscape, which is sacred to the Gunditjmara people.

The Warrnambool City, Corangamite Shire, Glenelg Shire, Moyne Shire and Southern Grampians Shire Councils are all within our service area.

The region’s agriculture (particularly dairying), forestry, education, manufacturing, tourism and healthcare contribute more than $5 billion in gross regional product to the Victorian economy each year.
