Wastewater from Rangataua township is transported through 4.1km of pipelines to the Rangataua Wastewater Treatment Plant. A map of the collection network is provided in the link at the bottom of this page.
Wastewater Treatment Plant
The Rangataua Wastewater Treatment Plant provides treatment of wastewater through the following steps:
1. Primary Treatment
1.1 Primary Oxidation Lagoon: Wastewater is piped into a Primary Oxidation Lagoon where heavier solids separate from the wastewater through settling as sludge to the bottom of the pond. This sludge is colonised by anaerobic bugs which help to break it down by using it as a food source. Bugs also live suspended in the wastewater and use up organic matter “food” throughout the lagoon.
3. Tertiary Treatment
Discharge of Treated Wastewater to the Environment
