Waikanae treatment plant upgrade
A 24-month upgrade to increase earthquake resilience and to replace aging equipment at the Waikanae Water Treatment Plant began in February 2022.
This upgrade is part of our commitment to provide safe, clean, reliable and resilient drinking water to homes and businesses. The Waikanae Water Treatment Plant provides drinking water to 41,000 people in Waikanae, Paraparaumu and Raumati.
The project is stage two of a planned three-staged upgrade of the Waikanae Water Treatment Plant. These works are part-funded by a $5.2 million grant from the Government’s Three Waters Reform Programme and include:
- enabling works to move utilities such as telecommunications lines and stormwater pipes out of the way for excavations needed for the clarifier (2022)
- building a new clarifier (a large settling pond which removes suspended solids from the water), and
- planned renewals to replace pumps and dosing equipment which are getting towards the end of their useful life.
The works will also increase the seismic resilience of the water supply for Waikanae, Paraparaumu and Raumati.
