Ngunguru Waste Water Treatment Plant

An upgrade required for the Ngunguru Wastewater Treatment Plant involved the supply and installation of a precast concrete ultraviolet light (UV) treatment chamber at its existing wastewater treatment facility.

The Ngunguru wastewater treatment plant treats the sewage from the small coastal Whangarei township. The treatment plant was upgraded in 2009 to incorporate an aerated oxidation pond and wetlands and in 2011 the council decided to further upgrade its UV disinfection system to improve the quality of the final treated effluent.
