Scheme Overview

The Amuri Irrigation Company Limited (AIC) currently irrigates 28,000 hectares of land within the Waiau and Hurunui catchments. The original irrigation schemes (Waiau, Balmoral and Waiareka) all fall within the Amuri Basin and are operated by AIC.

The water take from the Waiau River is governed by minimum flow conditions in order to provide for instream values when the river is at low flow. The water taken from the Waiau River (for the Waiau and Waiareka schemes) is deemed to be highly reliable (99%), whereas the Hurunui River is only offers good reliability (95%). Reliability is measured as the amount of time during the irrigation season that water will be available averaged over the years of the record (this does not consider irrigation demand).

The irrigation season extends from early September to late April.

 

Storage:

Currently AIC does not have any storage facilities but is considering storage opportunities as the Huruniu Waiau River Regional Plan has increased the minimum flows for the Hurunui and Waiau Rivers, which has significant implications for AIC reliability. AIC has reached agreement with the Zone Committee on delaying the implementation of the increased minimum flows in exchange for prioritising improved management of land and water delivered through our Environmental Management Strategy and Farm Environmental Plans. We have met these milestones and are hopeful that minimum flows will not be increased in the near future.

 

Delivery Mechanism:

The AIC schemes are composed of open channel and a pressurised pipe network to allow for continuous supply for spray irrigation. 4,000 hectares of land is irrigated from the open race and 24,000 hectares is irrigated via the pipe network
