There is an ongoing untreated wastewater discharge from Moa Point. We strongly recommend the public stay out of the water on the South coast of Wellington. Do not collect kai moana.

Wellington Water is responding to a significant incident at the Moa Point Wastewater Treatment Plant which has resulted in untreated wastewater discharging into Tarakena Bay on the south coast.

Faq / The Treatment Process

The treatment process

All treatment plants are slightly different, but the process is generally similar.

Entering the treatment plant.

As wastewater enters a treatment plant it is passed through milliscreens. These are made of fine mesh (about two millimetre wide openings) and act as a sieve to stop any large solids in the wastewater getting through, such as wet-wipes, sanitary products, shampoo bottles, toys, plastic bags, etc (link to "Looking after your wastewater" page). Everything that doesn’t make it through the screens is collected, pressed to squeeze out the excess water, and then transported to a landfill. The liquid that does make it through the milliscreens then flows through a pipeline into an aeration basin.
