Ms McBain criticised the NSW's state government's position on Yass water in parliament last Wednesday.

She specifically criticised a decision to spend $2 million on upgrading an existing water treatment plant, described as a "short-term fix", rather than pushing ahead with the Yass Valley Council's preferred solution: a $31.2 million new water treatment plant.

The development of a water treatment plant is now at stage two of a three-stage plan to fix the town's water.

Discussions about going forward with a new water treatment plant have been delayed to 2022 with council and the NSW Department of Planning Industry and Environment to reconvene after council develops a business case for the development.

"My answer every time is 'Yes'."

Yass residents say they have spent thousands of dollars a year on bottled water to avoid drinking discoloured and foul smelling tap water, with some residents fearful of bathing in the water.
