New King Island Water Treatment Plant opened

TasWater has today officially unveiled its new King Island Water Treatment Plant (WTP). 

The completion of the project represents a significant milestone for TasWater but more importantly, for both the Currie and Grassy community.

The multimillion-dollar infrastructure project now supplies water to both Grassy and Currie customers through a pipeline, spanning more than 26 kilometres, sourcing water from the Upper Grassy Dam.

TasWater CEO Michael Brewster said the treatment plant can treat about a million litres of water a day, meeting the needs of the growing Currie, Grassy and surrounding areas for years to come.

"The new plant brings water treatment on the island up to modern day standards, and features controls and stringent processes to treat the water consistent with the requirements of the Australian Drinking Water Guidelines."

Construction of the project started in November last year, taking about 12 months to completion.

"It is extremely satisfying to now see this new plant fully operational and I recognise the considerable amount of work carried out by our local contractors and joint venture partners Laurie Curran Water and MSD," Mr Brewster said.

“We are pleased to have worked closely with the King Island Council and Stornoway, who manage all our treatment and network facilities on the island, along with other stakeholders and companies to bring this project to fruition.”

"I appreciate the support the council has provided throughout this project and thank the community and nearby residents for their patience during the construction period."

“The King Island Water Treatment Plant demonstrates TasWater's commitment to the economic development of the island and Tasmania, and I am confident it will provide enduring benefits to the community and the environment,” Mr. Brewster said.

To mark today's official launch, a ribbon-cutting ceremony this morning with official guests taking a tour of the new water treatment plant site at Grassy.
