Start-finish: August 2017 – November 2018
Location: Army Bay Wastewater Treatment Plant, Army Bay
Status: Construction
What's happening?
Read the latest update on the Army Bay project.
The Army Bay Wastewater Treatment Plant currently services the population of Whangaparaoa Peninsula, Orewa, Hatfields Beach and Silverdale. Operational since 1982, it treats wastewater and discharges it through a 2.8 kilometre outfall pipe that extends one kilometre out into the fast-flowing Tiri Channel.
The existing outfall pipe is aging and not designed to cope with future growth. Work is underway to install a replacement pipe which will be sized sufficiently to accommodate for predicted population growth. The pipe will be installed from the Watercare’s Wastewater Treatment Plant across the peninsula, within the New Zealand Defence Force restricted land area.
Installed using trenchless technology, will go underground and discharge at the same location as the existing pipe.
What are the benefits?
- Allowing for future population growth
- Upgrading of infrastructure pipes, ensuring network reliability
How will the works affect you?
- Constructed mainly within New Zealand Defence Force-restricted land, the project will have minimal impact on the community
- Increased truck movements to and from the treatment plant site
