This programme will improve beach water quality in the Waitematā harbour and help to reduce volumes of waste water going to the Manukau Harbour.
Work for this will include:
- new stormwater pipes
- a Waterview stormwater separation
- the St Marys Bay overflow diversion project and
- water quality improvements across the western suburbs.
Contaminant reduction programme

It will also target the volume of sediment slipping into our waterways.
Urban and rural stream rehabilitation programme
A programme to improve the ecological health of our streams through riparian planting to create improved habitats and minimise stream erosion.
Septic tank and on-site wastewater programme
An improved compliance programme to ensure wastewater systems are regularly inspected and maintained to reduce the amount of waste water entering our waterways to help improve water quality.
A programme of investigative work to establish the sources of plumbing defects and illegal connections causing contamination of our beaches through our networks.
