Culverden, New Zealand

ec-large
Project execution period

September 2016 – September 2017

Project description

The Amuri Irrigation scheme delivers water to over 22,000 hectares in the Amuri Basin, taking water from the Waiau and Hurunui Rivers.

The North Canterbury farmland was threaded with a network of pipelines totalling 130 kilometres. The three main pipelines formed the majority of the network and provided water under pressure to shareholders of the Amuri Irrigation Company. The scheme delivers pressurised irrigation water to 160 property offtakes including isolation, flow measurement and pressure management. 

Contract value

NZ$68 million

Scope of work

The contract included the procurement, construction, installation and commissioning of the pipe distribution network of over 130km.

Further to the pipe network Monadelphous were responsible for the construction and integration of the intake infrastructure (ponds), road crossings, river crossings and the design and construction of nine (9) pump stations.

Supply, installation, commissioning of a new centralised control system to facilitate remote monitoring and automatic control, were also completed under the scope.

Highlights and achievements
  • While not specifically in scope, our design team provided alternative design recommendations, which were executed, contributing to shared project cost savings.
  • Implemented purpose built self-unloading pipe trailers for the transport of large diameter GRP pipe to work crews.
  • Monadelphous mobilised excavators, a padding machine, loader and grader from its Australian stocks and the plant and equipment played an integral role in the formation of self-execution teams for pipe install.
