Wastewater Treatment and Disposal

​We operate and manage the wastewater network within Cambridge, Karāpiro, Te Awamutu, and Kihikihi. The management and operation of the network is done internally, maintenance is delivered through a combination of in-house staff and external contractors.

We provide a wastewater treatment and disposal service to the urban communities of Cambridge, Karā​piro, Te Awamutu, and Kihikihi. There is also a facility at the Cambridge Wastewater Treatment Plant for the disposal of septic tank waste.

Our assets include 11,024 connections, 246km of pipelines, 48 pump stations and two treatment plants.

How it works

Wastewater Treatment and Disposal is focused on two key areas:

  • Minimising the adverse effects of wastewater upon the community and the functionality of the district.
  • Minimising the negative impacts of wastewater treatment and disposal upon the quality of the natural environment.

Typically a wastewater network is made up of two main elements; reticulation of wastewater from source, and the treatment of wastewater prior to disposal.

Treatment plants

Our treatment plants take the raw wastewater and remove contaminants through a mixture of mechanical and biological processes. The treated wastewater is then disposed of into an adjacent receiving environment.

We operate two separate wastewater schemes of similar size; one for the Cambridge Township and Karapiro Village and the other services the townships of Te Awamutu and Kihikihi.

Both schemes consist of reticulation, pump stations and a treatment plant.
