Northern parts of the district receive water supply from Watercare Auckland.
Watercare has been maximising production at their Waikato and Onehunga water treatment plants and have been delivering up to 170 million litres of water a day. Without these vital plants, Auckland would be out of water by now.
Watercare have been expanding the Waikato Water Treatment Plant step-by-step to stay ahead of population growth. When it was first built in 2002, it produced 50 million litres of water a day. Since then, there have been five upgrades so that it can now produce 150 million litres a day.
