Nitrous Oxide Emissions Reduction Strategy 2024
Emissions reduction infographic
- Our hydrodynamic model has come a long way since its inception, with the final version being much more complex and challenging to manipulate than originally expected. At the same time, Auckland Council’s Healthy Waters is developing its own harbour model based on Watercare’s data.
- These models offer valuable insights that can inform the potential effects of future developments and land use changes on the health of the Manukau Harbour, including reconsenting of the Mangere Wastewater Treatment Plant (WWTP) discharge.
- We are committed to transparency, sharing data through specialist and community groups, and its findings will help guide the reconsenting of the Mangere WWTP in the early 2030s. The Mangere WWTP has consistently met consent limits and has significantly reduced nitrogen and phosphorus discharges, contributing to positive trends in the health of the harbour.
- We continue to work closely with independent experts and the community to monitor and improve its operations, and plans are in place for future upgrades and better nutrient management to further ensure the long-term health of the harbour.
