The national Drinking Water Operator Certification Framework originally adopted name “Certification” as it most accurately reflected the needs of the water industry at the time.

Over time, there has been confusion over the term as it relates to Certificates awarded as a qualification on completion of Vocational Education and Training.

Individuals hold a qualification, for example a Certificate II or III, but that does not mean they are “Certified”.

To remove this confusion the Drinking Water Operator Certification Framework and the WIOA Water Operators Scheme will change from certification to registration.

Certified Operators will be automatically recognized as “Registered Professional Operators”.

The administration system Acuario provides an easy-to-use interface for the administration of the scheme. Demonstrations of Acuario can be made on request.

If you are interested in becoming a Registered Professional Operator, contact WIOA.

Congratulations to the operators of the Rossarden WTP who were awarded the Ixom 2020 Best Tasting Tap Water in Australia.

The Rossarden Water Treatment Plant, which is run in partnership with water services provider TRILITY, beat every other finalist from around the country to win the coveted award.

This is the second time Tasmania has won the national award, in 2016 water from TasWater’s Barrington Water Treatment Plant was named the best in the country.

The award acknowledges that TasWater is delivering great tasting, safe and reliable drinking water to Tasmania’s regional communities.

Rossarden’s water will now go up against global competition in the International Best Tasting Tap Water Competition in West Virginia next year.

The community of Rossarden can now celebrate after being acknowledged as having the best tasting tap water in Australia.
