Western isthmus water quality improvement

The western isthmus water quality improvement programme is funded by an estimated $361.6m from the water quality targeted rate over 10 years.

Project aims

The programme aims to significantly reduce wastewater overflows into the Waitematā Harbour and reduce stormwater entering the wastewater network.

It involves numerous major infrastructure improvements to the stormwater and wastewater network in collaboration with Watercare.

Other goals include:

  • reduce risks to public health
  • remove the permanent health warning status of both Meola Reef and Cox’s Beach
  • reduce intermittent beach closures in this area over the next 10 years.

Current infrastructure work

Some of the major projects already underway:

The current work complements Watercare's Central Interceptor programme, a 13 km pipeline costing $1.1 billion expected to be completed in 2025.
