Project Care
Auckland, New Zealand
This community driven project for North Shore City, in New Zealand, is directed at cleaning up pollution of beaches for community recreation and the health of its 190,000 residents. Project Care will take 20 years to implement and requires approximately NZ$300 million to complete.
Maunsell (as Meritec) was involved in:
- scientific data collection to detect and quantify sources of pollution
- computer modelling of wastewater and stormwater systems to determine quantities of sewer overflow and stormwater pollutants
- development of integrated trunk wastewater and stormwater reticulation network and receiving waters computer modelling to develop an understanding of the operation of the wastewater and stormwater systems serving North Shore City and their interaction with and effects on the marine environment of the Hauraki Gulf and Waitemata Harbour incorporating climate change considerations
- use of dynamic cost optimisation software to identify the optimum engineering solutions for defined levels of service
- research on alternative and sustainable technologies for reducing the pollution loads
- development of a range of options for public consultation allowing for population growth and rising environmental expectations over the next 50 years
- detailed benefit, cost and risk evaluation of preferred option
- production of wastewater system Improvement Plan and an associated Implementation and Monitoring Plan including regular strategic review.
Significant features
- Integrated approach to engineering and community involvement in decision-making.
- Project is subject to international peer review (Danish Hydraulics Institute).
- Early action plan from rehabilitation and recommissioning of existing assets has already shown immediate environmental benefits.
Project Care is the forerunner and now best practice for other similar projects across the Auckland region.
