St Marys Bay area water quality improvement project
We have installed a pumping and screening station, as well as a new pipeline, to reduce combined wastewater and stormwater overflows and increase swimmable days at St Marys Bay and Masefield Beach.
Improvements of the stormwater system
The $37.8m project in St Marys Bay area is part of the
Western Isthmus Water Quality Improvement Programme to clean up the Waitematā Harbour.
The work will:
- significantly reduce combined wastewater and stormwater discharges into St Marys Bay and Masefield Beach
- improve water quality at these beaches making it safer for swimming, sailing and paddling
- improve the environment for people, birds and marine life
- help us better manage increasing demands on the system as our population grows.
How we've done this
A new 2km long pipe will store combined stormwater and wastewater that would otherwise flow into St Marys Bay and Masefield Beach.
