‘Momentous achievement’ as Waiohine reservoir comes into service

The Waiohine Treated Water Reservoir has been officially opened and will increase water storage for Featherston and Greytown by around five times.

The reservoir was brought into service on Wednesday 9 February and adds an extra 8 million litres to the existing treated water storage capacity.

The commissioning of the reservoir brings an end to the project which began in 2019.

Wellington Water’s Chief Advisor Drinking Water, Laurence Edwards, said the reservoir will offer much needed water supply resilience to the community.

“The new treated water reservoir will provide a greater level of water supply resilience for both Featherston and Greytown, particularly in the summer months when demand is high,” he said.

“This new asset provides buffer storage to help us better manage through adverse conditions or unexpected events, like the ones experienced in the last few years from storms and power cuts.

“It will also allow the treatment plant to be taken offline for an extended period of time when required, without impacting the delivery of safe drinking water to the community.”

SWDC Group Manager Partnerships & Operations Stefan Corbett said the commissioning of the reservoir was a significant step forward. 

“This is a momentous achievement for all involved and will ensure a more reliable water supply,” he said.

“I know our community has been looking forward to it and will welcome this significant progress.”
