5-Waters Services

The availability of clean safe to drink water and the safe disposal of wastewater are fundamental to the health and welfare of the Selwyn community.

The 5 Waters service provides clean safe to drink water for households and removal of wastewater and rain water in a way that protects the health of the population and natural environment. The 5 Waters service also provides river water for livestock and drains certain land so that it is usable. These services are provided through 81 separately rated water based schemes within the District.

The 5 Waters assets are valued at $538 million with water supplies valued at $140 million, wastewater schemes $193 million, stormwater $34 million, land drainage $43 million and water races $128 million.

Drinking water is provided by the council to over 75% of the population of the District, around 41,000 people. By comparison, wastewater services are provided to approximately 29,000 people. The largest consented wastewater treatment and disposal area is the Pines Wastewater Treatment Plant, servicing Rolleston, West Melton, Lincoln, Prebbleton and Springston (the Eastern Selwyn Wastewater Scheme).

Activity Goal

Our goal for the 5 Waters activities is:

‘To provide water services that meet all relevant standards and are at a service level the public can afford and have confidence in, now and forward into the future’.
