Featherston Wastewater Treatment Plant
At the Featherston Wastewater Treatment plant, sewage flows through a facultative pond, a maturation pond, and ultraviolet treatment. Discharge of the treated effluent is managed to Donald’s Creek depending on the conditions of the Resource Consents.
The plant was granted new consents on 25 August 2009 with a variation granted on 12 November 2010. These consents expired on 25 August 2012. The plant is currently operating under this expired consent. An application for new consents is on-going.
In general, the consent allows SWDC:
- to discharge treated wastewater to Donald’s creek at up to 9,000 cubic meters per day in dry weather and up to 12,000 cubic meters per day in wet weather.
- to discharge odours and other contaminants from the treatment process within the boundary.
