The water races exist to supply drinking water to stock animals and, in rare cases, to rural households.

Their secondary purposes are firefighting, 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 in snowThe Council Water Race Management Plan sets out the key principles to be followed in managing the water race network. The Plan gives a specific statement of intent for the network, details key objectives/outcomes, and outlines best practice guidelines to be followed in managing and operating the network.

In addition to making an application to Council, it is the applicant's responsibility to consult with Environment Canterbury prior to excavation works being undertaken in or adjacent to a water race to determine whether resource consent is required (earthworks adjacent to a surface water body).

Irrigation Applications

Water race rate payers in all three schemes can apply to irrigate house gardens from the water race up to a maximum of 4,000 litres per day. Non-commercial irrigation for establishment of shelter-belts can be applied for, for a 2 year period.

Council hold an Environment Canterbury consent that allows water for commercial irrigation to be taken from the water race in the Paparua scheme. Irrigation water is allocated based on availability and a roster is reissued on 1 September each year. Amounts of available irrigation water are influenced by river levels which is reflected in the irrigation roster. Annual irrigation charges for 2017/18 are $291.42 per litre per second allocation (excl GST). Further details on the types of irrigation available are outlined in policy W101 and sections 6.9 and 6.10 of the bylaw.

Building Setback from a Water Race

To ensure that water races can continue to be maintained, Council’s standard building setback from the top of a water race bank is 10 metres, as outlined in the water race bylaw Section 8.21. A reduction in building setback can be applied for using the form found here.

Fencing Stock

To maintain the quality of water race water, Council require that heavy stock (cattle, deer and horses) are prevented from physically entering the water race (section 8.5 of water race bylaw). Land owners are encouraged to install drinking bays in the water race which allow stock to drink but not stand in the water race. Details of standard designs:

Water Race Planting

Council support the planting of water races to help to increase biodiversity, reduce weed growth and stabilise race banks. Council need to make sure that plant selection and placing are suitable.

Further details and a list of approved plants.

Water Race Cleaning & Spraying

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.

Council undertake spraying of vegetation emerging from some Council cleaned water races. Spraying of water race banks can cause them to slump and collapse.  Council do not recommend land owners spray water race banks or directly into water.

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

Poor Water Race Supply

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.  If the problem cannot 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 outage (provided it was reported to Council). Applications for water race rebates should be made in writing to waterraces@selwyn.govt.nz.

Water Race Closure

If all rate payers on a section of water race agree to its closure, an application can be made to Council to close the race. Details of the closure process. No closure can be undertaken without Council approval.
