The availability of clean safe to drink water is fundamental to the health and welfare of the Selwyn Community. Drinking water is provided by the Council to over 75% of the population of the District around 41,000 people. Water is supplied for public needs including household, gardens, and public reserves.

Water Schemes

W are one of the largest water suppliers in the region of Canterbury and we manage over 30 water supplies across the District that spans from Arthur's Pass to Taumutu in the southern region. The diverse geographic location brings the needs to provide water that meets the particular communities' needs whilst acknowledging the varied number of inherent challenges imposed. For instance, our schemes at Arthur's Pass is frost prone with water demands fluctuating depending on movement of tourists and visitors, whereas in our scheme at Rolletson, a sustained water demand is generated from dense urban population and growing industries.

Further information about the districts water supplies is available in the 5Waters Activity Management Plans.

Water Demand Management

The Council's Water Conservation and Demand Management Plan [PDF, 1593 KB] provides background information and an analysis of water management in the Selwyn District, and presents a plan for improved water demand management. This plan was approved by Council on 8th June.

High growth in the eastern urban townships including Rolleston, Lincoln, West Melton and Prebbleton, is driving the need for more public drinking water from these townships sources - both at existing and new sites. For some townships residents are able to self-monitor scheme capacity and adjust water usage to suit e.g. don’t irrigate lawns while the scheme is under pressure.

"Water Sense" Campaigns

We always encourage wise water consumption.

During spring and summer months, water consumption in the Selwyn District will increase significantly. This is mostly due to an increase in residential water use for garden and lawn watering. Simultaneous irrigation in some areas result in reduced water pressures in the network. Some water supplies may struggle to meet demand and Council will put in place water restrictions. Check the website often for our Water Sense campaign every summer period.

All current township water restrictions are notified via this website, Facebook and https://selwyn.getsready.net/. Council also informs its rate payers through etxt and emails.

The water conservation page provides more information and water saving tips.

Water Quality

There are nine river/gallery intakes, and 24 deeper groundwater takes. Source, treatment plant and reticulation water is regularly tested for the presence of bacteria. More about water quality.
