As with any irrigation development, a water entitlement and water use licence is needed. Information about the water requirements of perennial pasture is presented in Step 2.3.1.

Flow rate – Border-check systems can be designed to suit a large range of flow rates (see the Agnote “Border-check Irrigation Design”). High flow rates enable more land to be irrigated in a given time, minimising labour or automation costs.

Water quality – The main water quality issue is salinity (electrical conductivity, or EC), and this is normally only a concern if ground water (or in some cases surface drainage water) is being used. Contact your local DPI office for information on required shandy ratios of good-quality surface water (from the channel) with poorer quality water from the reuse system, drainage diversion, or ground water.
