The Wastewater Treatment Plant on Kioreroa Road is the largest processor of wastewater in the Whangārei district.
It processes an average of 21,000 cubic metres of wastewater from homes and businesses per day and has a replacement value of $65 million.
It treats wastewater for Whangārei’s main urban area, from Te Kamo in the north, Maunu in the west, Raumanga in the south to Onerahi and Whangārei Heads in the east.
Cleaning up the city’s wastewater involves a lot of steps – it is strained, mixed, filtered, feasted on by live bacteria, dried and disinfected. The resulting solid waste is taken to landfill and the treated water is discharged via constructed wetlands into the Limeburners Creek.
