Council runs a treatment plant in each of the 6 main townships.

Wastewater Treatment Plants

Waipukurau & Waipawa

 The Treatment Plants were first constructed in 1975 & 1967 as single stage oxidation ponds with Waipukurau having pre-treatment being provided with an Imhoff tank

Since then a number of upgrades have been carried out including the demolition and removal of the Waipukurau Imhoff tank. The treatment process in both plants now consists of a facultative area, a biological attachment (BAS) area, and a floating wetland covered area all within the oxidation ponds.

The effluent from the ponds is then pumped through sand filters with the addition of chemicals, UV irradiated, and discharged into the Tukituki River (Waipukurau) and Bush Drain (Waipawa).

Otane, Porangahau, Takapau and Te Paerahi

 All four networks discharge by gravity, or pump stations, into oxidation ponds.  Because of the differing nature of the incoming wastewater these ponds have either aerators, baffles, covers or floating wetlands to aid the biological process of treating the wastewater
