Waikato Water Treatment Plant – Increasing water supply

The Waikato Water Treatment Plant is one of the most sophisticated water treatment plants in Australasia. Starting in 1999 and completed in 2002, Beca was part of the Waikato Water Joint Venture responsible for successfully delivering the $100 million water supply.


The project involved the construction of pump stations and an advanced treatment plant, as well as 37 km of pipeline to deliver 150 million litres of treated water per day from the Waikato River to a reservoir in Manukau. Many new and cost-effective design features were introduced, setting a new benchmark for water treatment in New Zealand. They include the use of Zeeweed® membrane ultra-filtration technology as the core treatment process, to help purify and protect public health.
