Ixom 2021 Best Tasting Tap Water Competitions

All water providers/councils were invited to participate in the Ixom Best Tasting Tap Water competitions, as WIOA searches for the best tap water in each State. Unfortunately, there can only be one winner per state who will now represent their state in the national final to be held in early 2022.

What were the judges looking for?

  • Colour Water that is completely translucent without any white or brown tones
  • Clarity Crystal clear water with minimal turbidity
  • Odour Samples that are pleasing to smell – nice scent

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

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.
