In times of drought and climate change, this extensive project could not be more important.
The IHS (Integrated Horticultural Supply) project involves replacement of channels with pipes in the horticultural zones of the Murrumbidgee Irrigation area.
As the twenty or so existing gravity supply systems reach the end of their service life, it is more cost effective to replace them with buried plastic pipe than with concrete lined channels. Whilst there would be some leakage losses stopped by either of these options, the greatest gains in water efficiency from this project will come from improved on-farm practices.
Based on similar projects elsewhere it is anticipated growers will take up the opportunity to convert from flood irrigation to micro irrigation when the IHS scheme arrives. Many have already upgraded, and most will find the upgrade expensive. But everyone agrees every effort must be made to save water and ease the pain from severe water restrictions.
Since winning the second round of tenders, HydroPlan has provided independent design and contract documentation services to Murrumbidgee Irrigation Limited - Australia's largest private water supplier. The first three projects involve pump stations with combined capacity over 2000 L/s and heads over 120m- but plans are underway for bigger ones.
The grower outlets are monitored in real time and can be closed off by remote control when required. Water is delivered under sufficient pressure to avoid re-pumping. On this project, water and energy will be saved.
Muswellbrook Race Club is one of the premier regional race tracks in NSW located in the upper Hunter Valley.
The existing pop up sprinkler irrigation system was under performing with race course maintenance staff forced to irrigate both the course proper and B grass training track...
