We collect, treat and dispose of wastewater from about 26,000 homes and businesses across the District. Our network includes 582km of pipes, 141 pump stations and nine treatment plants. The wastewater system that serves Whangarei City is the largest, with 84% of all connections linked this network. The main network in Whangarei has been built in stages and some of it is over 100 years old. We are steadily replacing those that are old and damaged and growing the network as our population grows. Here’s some of the work we have coming up:
Sewer extensions and upgrades
A new sewer line will be installed to increase the capacity of the system in Kamo to allow for more waste water being generated as the Kamo population increases.
Waipu Cove will get a lot of new sewer pipes over the next three years to address historical problems with the wear and tear to the system there.
The Whangarei Heads Sewerage Scheme will be extended to accommodate more waste water being generated by the increase in population there.
The telemetry system that tells the district’s pumping stations when to pump sewage along the lines will be upgraded.
Kioreroa Road Wastewater treatment plant
Kioreroa wastewater treatment plant is the largest in the district, serving most of the city. The treatment plant will be upgraded in the next four years to cater for population increase and odour control will be introduced. This will include covers on tanks and other processes.
District Wastewater treatment plants
The Ngunguru Waste Water treatment plant’s wetlands will be upgraded. The land area irrigation at Ruakaka will be extended to accommodate growth. New land irrigation fields will developed at Waipu and the treatment plant there will be upgraded.
Major planning projects
The resource consent for the District’s main wastewater treatment plant at Kioreroa Road in the city is due to expire in 2021. Before then an application for a new consent will be prepared. This will involve major studies and reports, and public consultation.
