Huia Water Treatment Plant Replacement

Detailed Planning
Huia Water Treatment Plant Replacement

The Huia Water Treatment Plant Replacement project involves construction of a new treatment plant with a daily capacity of 140 megalitres. This represents an increase on the existing plant's capacity of 126 megalitres. The replacement treatment plant will be located on the Watercare-owned Manuka Road, Waima site with reservoirs to be located on the Woodlands Park Road site. 

The project will replace the existing Huia Water Treatment Plant which is approaching the end of its operational life.
