Australia’s best tasting tap water was decided on Saturday 12 November 2022, when WIOA with great support from Richmond Valley Council hosted the Ixom 2022 Best Tasting Tap Water in Australia competition, putting interstate rivalry to the ultimate test.

Water authorities from various regional and metropolitan areas around Australia had already participated and won the Grand Final in their respective state-based competitions, and were then put head to head for the National Title and the chance to represent Australia.

The National competition was hosted by last year’s winner, Richmond Valley Council in Casino.  An exhibition space at the Primex Field Days was set up with the countries best samples sent for judging, with over 250 people tasting all 6 of the samples.

Ultimately the team from Melbourne Water with their sample from the Creswell WTP were announced as the 2022 Best Tasting Tap Water in Australia.

The Creswell sample will now be sent over to the USA and represent Australia at the annual Berkeley Springs International Water Tasting Competition held in West Virginia, USA.

Quotes attributable for the taste test

The general public would probably be surprised to learn the complexities involved in delivering high-quality water to our taps each day.

Many of us turn on taps for a drink, to cook and shower, with little consideration of what it takes to operate and maintain the water infrastructure. The competition is a testament to the excellent quality of Australian water and to the diligence and commitment of the operational employees who deliver it to our communities.

We want to celebrate our unsung heroes – the water operators and the maintenance crews who work all year-round to ensure we have high quality water, which is essential to keep us alive.

Many of WIOA members are working hard behind the scenes for their communities to deliver high quality drinking water, whilst dealing with the impacts of COVID-19 and before that drought, fires and floods in various parts of Australia, and we want to use the Taste Test Competition to let people know the great work that is going on in local communities around Australia as these teams help shape and secure Australia’s water future.

Australia’s 2020 Best Tasting Tap Water is the Best in the World

Water from a small regional town in Tasmania, which was once deemed unsafe for consumption, is now the best tasting in the world.

Water from the Rossarden Water Treatment Plant in the state’s Northern Midlands represented Australia after winning the WIOA –  Ixom Best Tasting Tap Water in Australia competition in 2020.  The top drop has now won the Best Municipal Water for 2021 at the Berkeley Springs International Water Tasting event in West Virginia, USA, a global event that judged water from five continents, 14 countries and 19 US states.

This is the first time water from Australia has won the prestigious award, which is a major coup for the nation and the state.

The Rossarden Water Treatment Plant is run in partnership with water utility services provider TRILITY, which built and designed the facility as part of TasWater’s 24glasses Regional Towns Water Supply Program in 2018.

“It’s a great result for the community and is particularly pleasing because Rossarden was part of our 24glasses Regional Towns Water Supply Program. With the plant in place, the community can take advantage of the water that flows from Ben Lomond knowing it is safe to drink. It’s a welcome bonus to see it recognised as not only the best tasting drinking water in Australia, but now the world.”
TasWater Senior Water System Optimisation Scientist Stephen Westgate

WIOA’s IXOM Best Tasting Tap Water Competitions celebrate the work undertaken by many WIOA members who work hard behind the scenes for their communities to deliver high-quality drinking across Australia.
