The Central Plains Water Irrigation Scheme will provide water for irrigating some 60,000ha of land on 400 farms in the Central Canterbury Plains, New Zealand.

There will be a 60km-long canal of up to 40cumecs capacity on a level grade between two rivers to enable water to flow in either direction, according to water availability and demand.

From there, water will be supplied down the Plains by gravity through 400km of delivery network with two areas of pumped extension above the canal to service some 10,000ha. Work includes leading the initial feasibility studies and advancing the scheme to preliminary design to obtain planning consents.
