On 30 May 2017 the Watercare Board selected Manuka Road in Waima (Titirangi) as the location for the replacement Huia Water Treatment Plant. The Waima location was selected following a comprehensive assessment which initially identified more than 100 sites. These were reduced to 19 following further analysis. A multi-criteria analysis narrowed the 19 options to the four shortlisted sites, two in Parker Road, Oratia, the existing site and Manuka Road, Waima.
The replacement treatment plant is proposed to be set back at the intersection of Woodlands Park Road and Manuka Road and is part of a wider improvement of the western water supply. Two new treated water reservoirs are also planned along with a treated water pipeline suppling the community between the plant and Albany. Sections of the raw water pipelines from the dams will also be upgraded.
