Water management

The Department of Primary Industries and Regional Development supports dryland and irrigated industries by providing information on best practice water management. This includes information on rainfall-runoff capture, storage and use, and management systems to prevent land degradation.

Support and knowledge on practices for irrigation as well as planning and design tools, to support farmers manage water in a changing climate, are being continually updated. Our work complements the Department of Water and Environmental Regulation’s Rural Water Planning Program, which offers incentive schemes, grants, planning and technical services, emergency water arrangements, and information on best practice water supply improvements.

  • In Western Australia, carrots are grown on sandy soils of low water-holding capacity. When evaporation exceeds rainfall, irrigation is important to ensure high yields and quality.

  • Shallow relief drains are effective at removing surface water from flooded land. Removing flood water reduces waterlogging and groundwater recharge and improves productivity of the soil.

  • Permanent raised beds are a practical and economic means of managing some waterlogged sites in wetter areas of the Western Australian grainbelt.

  • Leveed deep drains are deep excavated channels with sloping floors and sides and levees on both sides.

  • Open deep drains are deep excavated channels with sloping floors and sides, designed to intercept and drain surface (usually fresh) and subsurface water (usually saline in Western Australia) from a

  • Jujubes (or Chinese dates) are a new horticultural industry in Western Australia. This page outlines recommendations for irrigating jujubes in WA.

  • Water quality can influence the efficacy of chemicals used in spraying crops and pastures.

  • Organic material washed into dams can lead to water becoming unattractive to livestock and possibly toxic.

  • An evaporation basin is a natural salt lake or engineered earth structure designed to store and evaporate saline water.

  • A roaded catchment is a water-harvesting structure designed to increase the amount of run-off from the catchment above a receiving farm dam.
