Water Schemes

Selwyn District Water Schemes

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 schemesWe manage over 30 water supplies across the District that spans from Arthur's Pass to Taumutu in the southern region.

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

"Water Sense" Campaigns

We always encourage wise water consumption. All current township water restrictions are notified via this website, Facebook and 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.

Backflow Prevention Requirements

The backflow prevention policy sets out the backflow prevention requirements for new and existing properties in the district.

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 8 June 2016.

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.
