Wastewater Projects

Wastewater projects to improve the quality, capacity or reduce risk on the wastewater schemes are required to meet the target levels of service, accommodate growth and maintain the wastewater process to an acceptable condition.

  • Central Rangiora trunk sewer: A new large diameter pipeline is being installed from the Rangiora treatment plant through Central Rangiora over the next eight years to cater for growth and reduce overflows. There will be news stories and targeted letter box drops with affected residents and businesses throughout the construction period. Find out more about this project on our Rangiora wastewater pipe upgrades page.
  • A new 1.4km sewer rising main is being installed in Kaiapoi, from the Parnham Lane pump station, along Vickery Street, Ohoka Road and Charles Street, and will connect to an existing pipe near the Kaiapoi River on Raven Quay. Find outmore about this project on our Parnham Lane sewer rising main page.
