Huia water treatment plant replacement



Built in 1928, the Huia Water Treatment Plant, in Woodlands Park Road, is nearing the end of its useful life.

Great turn-out for Huia Water Treatment Plant tours

The Huia Water Treatment Plant tours on 8 and 9 April attracted more than 320 people, who were given a closer look at how the plant operates. Watercare staff were on hand to provide information and answer questions. 


Green Party candidate and television presenter Hayley Holt was one of the visitors.

Exhibition Drive

Watercare owns Exhibition Drive land for water supply purposes.​ We recognise the significant amenity value of this walkway. We have been working, and continue to work, constructively with Auckland Council on the potential transfer of this asset to the council so that it retained as part of the regional park and operated accordingly. 

We would retain easements for specific infrastructure and ownership of some portions of land that are of strategic importance to the area and Auckland’s water supply system. We are required to work through a process with Auckland Council to ensure that we meet our statutory obligations.

We have not entered into any discussions with developers regarding Exhibition Drive. We reject any claims to the contrary, that have been made by other uninformed parties.​


What’s happening?

Planning is underway to optimise the future treatment and delivery of water from the dams in the Waitakere Ranges to best meet demand as Auckland continues to grow. In some cases, this will require replacement of old assets nearing the end of their operational life. The most significant and costly of these will be the replacement of the Huia Water Treatment Plant and associated water transmission infrastructure which in some cases is nearing 90 years-of-age. 

As part of the process to identify a suitable site for a new water treatment plant, we undertook a comprehensive site identification process using geographical information systems based on four key principles. Forty-four potential sites were identified for further assessment using a multi-criteria assessment method. This assessment looked into environmental, social, cultural and economic factors. The process ultimately resulted in three preferred options being selected for final consideration. Please refer to the Tonkin and Taylor report and the GHD shortlist site development report.

Further detailed work is now underway on non-financial and environmental attributes such as social and community impacts. Feedback from the community open evenings will be incorporated into these reports and considered as part of the final decision making process.

The project is part of our wider Western Water Supply Strategy. 

Working with you

Decisions made regarding water servicing are important, not just for the current communities but for future generations too. We are committed to working closely with the community to identify the best option to service existing and future supply needs. 

Open evenings

On Tuesday 21 February, a community meeting was held in Oratia to discuss the replacement of the Huia Water Treatment Plant. A second meeting was held at Woodlands Park School on Wednesday 22 February. These sessions provided an opportunity for Watercare staff to answer questions and hear feedback on the options.

Why build a new treatment plant?

Huia Water Treatment Plant, located at the corner of Woodlands Park Road and Manuka Road, is Auckland’s third largest water treatment plant. Constructed in 1928, the plant is nearing the end of its operational life and needs to be replaced. In order to continue supplying Auckland with high quality water from the west, as the city grows, a project is underway to assess the options and requirements needed for a replacement water treatment plant.
