We are upgrading the Mangere Wastewater Treatment Plant and improving our biological nutrient removal process. This project is part of an upgrade of the Mangere Wastewater Treatment Plant.
Read the latest update on the BNR expansion project.
The centrepiece is a facility that uses bacteria to remove nitrogen and phosphorus from the wastewater stream. High levels of these nutrients in waterways can harm the environment.
What are the benefits?
- Better water quality.
- Protection of marine life.
