To be leaders in Water Management providing Reliable, Economic and Sustainable Supply
The area of the scheme has been broken up into four zones of approximately the same area and volume. The Roster breaks the scheme at the Eyre River and separates Distributary Race 3 from the main race and Woolfs Road and the Cust River catchment. These are significant natural splits.
This would enable the restrictions to be applied in stages. A 25% reduction, for example, would require that each area in turn would have no water for two days, followed by six days of water.
For a 50% reduction, each area would have four days of water and four days without. The distant parts of the scheme, Areas 2 and 4, would have water first, then areas 1 and 3.
For a 75% reduction each area would only get water for two days then wait six days before water was rostered again.
Restrictions stop and start with little warning. For fairness, it is important that when restrictions are lifted the next area of the cycle becomes the start point when restrictions are applied again. This rolling sequence is necessary because, if a series of restrictions of two to four days is applied, the same area would experience all the restrictions and other areas might not have been restricted at all.
It is possible that some individual irrigators can restrict their application rate to 75%, 50% or 25% of their entitlement. The system could be cater for this individuality; however, it could create ill feeling and encourage cheating, because no one could be sure as to whether or not any particular irrigator was complying with the restriction. Clearly, an area-wide restriction is more easily policed. The scheme intake will be set to take the allowed flow for irrigation plus stockwater, and this system is the easiest managed to ensure compliance.
It is not permitted for an irrigator in a restricted area to arrange with a friend who is not irrigating in another area not under restriction, to use his water during restrictions. The company will ensure that NO available water is wasted.
A critical aspect from or point if view is that WIL must maintain detailed records of water use to be able to show that all irrigators have been treated equably.
