Moa Point Wastewater Treatment Plant

At the Moa Point Treatment Plant, wastewater travels through a series of screens, tanks, bioreactors, clarifiers and ultraviolet treatments before being discharged as liquid into Cook Strait.The Plant has capacity to discharge up to 260,000 cubic metres of wastewater per day.

Each day the Plant cleans and disinfects wastewater from about 180,000 people. It treats an average 850 litres of water (or about three standard bathtubs) every second and up to 3,000 litres a second during heavy rainfall.

Much of the Plant’s equipment and parts are nearing the end of their service life, which means its more prone to service interruptions and needs more maintenance.

A multi-million-dollar programme of work is planned over the next seven years to renew and upgrade equipment at the Plant to improve its operation, subject to funding being confirmed. This programme includes improving the reliability and effectiveness of the treatment, increasing capacity to handle population growth, and improving safety.
