Wastewater Treatment PlantsNgā wāhi rāwekeweke

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).

Survey

Following on from our media release in the CHB Mail on the 20th November, 2018 regarding the future of our wastewater treatment plants, CHBDC is investigating options for improved wastewater treatment and discharge schemes for the communities of Otane, Waipawa and Waipukurau.

To help us make the right decisions we want to hear about what is important to you - please complete this survey by Sunday 27th Jan 2019.

Look out for the results to be publicised in Feb 2019. This is the first step in our consultation process, there will be more opportunities to share your views next year.

Thank you for your feedback.

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
