Water is vital to Carterton’s homes, businesses, and environment. Our water hub is your central place to learn how our District’s water systems work, how we manage them, and how you can help use water wisely.
Carterton’s drinking water is treated and stored to provide safe, reliable supply for the community. We also maintain a historic water race system, delivering stock water across rural areas and supporting local ecosystems.

Where does our water come from?
Water supply for the Carterton district comes from the Kaipatangata Stream and two underground bores. These sources are dependent on rainfall.
Carterton’s main water supply at the Kaipatangata has relatively little storage capacity so daily collection and treatment of the stream water is closely linked to the volume of water being consumed.
District bore system
Carterton District Council constructed its supplementary bore system in 1990.
The main purpose of this system is to ensure that during times when the quality and quantity of the Kaipatangata supply is not adequate, the supplementary system can be brought on stream to ensure that residents have water for domestic use and township has sufficient water available for fire fighting purpos
