: Mid 2020-Mid 2021
What is happening?
An important part of our drought response and water supply resilience plan includes building additional treatment capacity at the Waikato Water Treatment Plant. This includes construction of an additional 50 million litres a day of treatment capacity adjacent to the existing plant.
What are the benefits?
In response to the worst drought on record. we have increasingly looked at the Waikato River and the associated treatment plant to maintain water supplies for Auckland. The plant allows us to prioritise water from the more resilient river feed, allowing the water storage dams in the Hūnua and Waitakere ranges more time to recharge and recover.
The Waikato Water Treatment Plant usually provides up to 30 percent of drinking water for the Auckland region. The Waikato River is a more drought resilient source than our water storage dams due to its large catchment extending all the way to Taupo. This project will enable an additional 50 million litres a day of treatment capacity.
How will this work affect you?
Part of the construction includes a work laydown area on Trig Road which is being used by our contractors for storage and parking. This will be utilised for the full construction period.
Some traffic layout changes along with speed restrictions will be in place on local roads during construction. Please follow traffic directions and take care around construction traffic.
Access to residential properties will remain open during the upgrade as the main construction works will take place at the existing treatment plant.
Construction and laydown areas will be fenced for the safety of the public.
Working hours will typically be from 7am to 6pm Monday to Saturday with extended hours from December 2020 until April 2021 as required. We will aim to minimise any associated noise and traffic movements at night and will notify you prior to any changes in construction hours.
