​​​​Warkworth-Snells-Algies wastewater services

We are planning to build a new wastewater treatment plant at Snells Beach.

Start–finish: 2016–2022
Location: Warkworth, Snells Beach, Algies Bay
Status: Design – consents granted 2017

What’s happening?

In order to service growth in the north-east Workworth area, we will be constructing a modern new treatment plant at the site of the existing Snells Beach plant.

Outcomes include:

  • Wastewater from Warkworth will go to the new Snells Beach plant via a new pipeline and pump stations. This route is still to be finalised.
  • The discharge of treated wastewater into Mahurangi Harbour will cease.
  • The upgraded ocean outfall will discharge about 600 metres off the coast, to the south of Martins Bay into the Hauraki Channel.
  • The existing Warkworth Wastewater Treatment Plant will be closed once the new plant is built.

What are the benefits?

  • The new plant will cater for the growing population expected in this area.
  • Advanced technology will produce very high-quality treated wastewater suitable for discharge into the Hauraki Gulf.
  • Future-proof for growth beyond 2051.
