Upgrading Westport’s drinking water supply
We supported Buller District Council to upgrade the Westport drinking water supply, without burdening the community with the cost.
The Westport drinking water supply is old and performs poorly but the challenge was updating the system in a way that would be cost effective for a small community of 5000 people.
Opus made Buller District Council’s project happen by supporting their decision process, securing a funding subsidy, designing the upgrade and facilitating construction.
The old treatment plant had some unique features including a series of 100 year old tunnels, channels and water races but the design didn’t meet required standards.
Initially we reviewed the plant after a failure delivered visibly poor quality water to the community. We prepared options for Council to consider, including taking water from the Buller River and building new treatment and storage facilities. They decided a major upgrade of the existing plant was the way to go.
Our team prepared an application to the Ministry of Health drinking water subsidy scheme and secured a $1.5m subsidy for the council – 50% of the upgrade cost.
Opus is a trusted partner to the council. We’re ensuring the upgrade is technically appropriate and cost effective. For years to come, this project will give people in Westport clear and safe drinking water.
