The water races exist to supply drinking water to stock animals across Selwyn District.

The Water Race network in central Canterbury began operations over 120 years ago and was established to provide reliable water source for agriculture. Council manages approximately 1,700kms of water race network that runs across the district. Water Races are run under three different schemes.Water race in snow

Water races have a secondary purpose of firefighting resources, irrigation and landscape/aesthetic.  All properties with access to a water race are rated for stock water regardless of whether the water is used.

Water Race Services

Council has contractors employed to manage the water races and to ensure there is supply across each scheme. Council contractor SICON does this work including river works at each intake, clearing grills and screens and setting flows across each scheme.

Council generally clean main water races when it is required and land owners are responsible for cleaning all other races (as outlined in Policy W103). Council contractors have legal rights to cross private property to clean a designated race. Property owners are responsible for maintaining all vegetation planted adjacent to water races.

To find out if your water race is your responsibility and to get advice on maintenance best practices please contact Council.

Poor Water Race SupplyDry Water Race

If you are experiencing a poor supply from your water race please report the issue to Council by phone or email helpline@selwyn.govt.nz. Council’s Network Management Contractor SICON will investigate and where possible remedy the issue.

Council cannot guarantee supply to the races and sometimes it can take a long time for the problem to be resolved (e.g. due to lack of water in the river), Council’s policy W109 enables a rebate of water race rates to be made for the duration of the prolonged outage (provided it was reported to Council). Applications for water race rebates should be made in writing to waterraces@selwyn.govt.nz.

Water Race Cleaning

Council generally cleans main water races when it is required and land owners are responsible for cleaning all other races (as outlined in Policy W103).

If there is a water race on or adjacent to you property you should regularly inspect, repair, maintain and clean to ensure there is a continuous supply of water downstream. Cleaning should include removal of built up silt, aquatic weed and grasses and pest plants in the race. Race cleaning work should be careful not to damage races or banks.

Clean Water Race Dirty Water Race

Clean water races should be free flowing, clear of silt, vegetation and other obstructions that prevent water from flowing. Land owners should keep adjacent plants and vegetation trimmed back from the water race.


Please contact Council to find out whether your water race is cleaned by Council or to get further advise on maintaining your water race.

Water Race Culverts

Each property owner owns their entranceway culvert over the water race and are responsible for it’s maintenance and replacement, if needed. Approval from Council is required prior to any structure being placed in a water race.
