CANOPy

Project Overview

Project CANOPy was initiated in January 2017 in response to long-standing concerns about the ongoing water quality issues in the western part of Auckland’s inner city.

CANOPy stands for Central Auckland Network Optimisation Programme and includes the suburbs of Grey Lynn, Cox’s Bay, Herne Bay, St Marys Bay, Freemans Bay, Westmere, Point Chevalier, Avondale, Waterview, Mount Albert, Western Springs, Epsom, Hillsborough, Lynfield, Mount Eden, Sandringham and Mount Roskill, commonly referred to as the Western Isthmus Area.

The project was undertaken jointly by Watercare Services (Watercare) and Auckland Council Healthy Waters (Healthy Waters).  The purpose of the project was to develop an affordable, timely and integrated infrastructure programme that:

  • Optimised existing and committed wastewater and stormwater infrastructure,
  • Improves water quality of the Western Isthmus waterways and Waitematā Harbour by reducing high volume and high frequency wastewater overflows, and
  • Enables the anticipated urban growth in the project area without causing further environmental effects.


MPS carried out a detailed options assessment for each CANOPy catchment; and a complementary suite of stormwater and wastewater projects to make the best use of the already committed Central Interceptor project.
