Council Approves $5.92 Million Upgrade for Pātea Water Treatment Plant
South Taranaki District Council has given the green light to a revised budget for the Pātea Water Treatment Plant Enhancement Project, approving up to $5.92 million to ensure the community continues to enjoy safe, high-quality drinking water.
The additional funding of $2.64 million will allow the project to move into the construction phase without delay, meeting compliance rules set by Taumata Arowai – New Zealand’s Water Services Authority.
Why the upgrade is needed
The Pātea Water Treatment Plant is being upgraded to meet the latest Drinking Water Standards and Water Quality Assurance Rules. After a successful pilot trial earlier this year, the Council opted for a modern biological filtration system instead of reverse osmosis. This approach delivers excellent water quality, is more efficient, and better suited to local conditions.
What’s changing?
The upgrade will include new treatment components such as:
- Biologically activated carbon filters
- Copper and carbon dioxide dosing systems
- UV and chlorine disinfection
- Improved filter cleaning and monitoring systems
These improvements will reduce ammonia levels in the water, helping maintain sufficient chlorine levels and ensuring compliance with drinking water regulations.
A big step forward for Pātea
Mayor Phil Nixon says the decision reflects the Council’s commitment to providing safe, reliable water for the community:
“This is a critical investment in Pātea’s future. We know how important a secure and high-quality water supply is for our residents, and this upgrade ensures we meet the highest standards while planning for long-term resilience.”
Tendering for the project is complete, and work will begin late January 2026 with expected completion in December 2026.
