New Zealand’s largest ever wastewater infrastructure project, the Central Interceptor, has officially begun, with the launch of the Tunnel Boring Machine at Māngere.
Currently, in the event of heavy rain Auckland’s central wastewater network overflows to local waterways and the Waitematā Harbour at more than 100 locations, and to the north-eastern Manukau Harbour at 14 locations. Untreated wastewater results in increased harm to the environment, contaminated seafoods, transmitted diseases to water users, and creates unsuitable conditions for marine life.
The existing wastewater pipeline that passes under the Manukau Harbour was built in 1964 and is reaching the end of its operational lifespan.
The Central Interceptor is an integral part of Auckland Council’s long-term strategy to manage wastewater, and will provide a series of essential benefits such as drastically reducing wet-weather overflows, reducing risks to public health and the environment, and meeting the needs of a growing Auckland City.
“This project is a positive reflection of the work that Auckland Council puts into facilitating the continued growth of Auckland as a world-class city and experience for our citizens”, says Whau Ward Councillor Tracy Mulholland.
More information regarding this project, as well as regular updates, can be found on Auckland Council’s website.
