Overview

Join us for a tour of the Moa Point Wastewater Treatment Plant, Wellington’s largest facility for treating and managing the city’s wastewater. At the Moa Point Treatment Plant, sewage travels through a series of screens, tanks, bioreactors, clarifiers and ultraviolet treatments before being discharged as liquid into the Cook Strait. It was granted new consents on 11 May 2009. These consents will continue for 25 years (expire 11 May 2034). In general, the consents allow WCC:

• continuously discharge up to 260,000 cubic metres per day of treated and disinfected wastewater into the coastal marine area via the existing submarine outfall
• discharge up to 4,500 litres per second of mixed disinfected, treated, and milli-screened wastewater to the coastal marine area during and/or immediately after heavy rainfall, when inflows to the Moa Point Wastewater Treatment Plant exceed 3,000 litres per second
• occupy the foreshore and seabed of the coastal marine area with the existing submarine outfall pipeline
• continuously discharge contaminants (including odour) to air from the Moa Point Wastewater Treatment Plant ventilation system.
