A survey of production nurseries that participated in WaterWork workshops found that information on average water use, water cost, pumping cost, maintenance cost, and hand watering labour cost was not known. A similar lack of data has also been found during the course of the RWUE project. The benefit of a system audit for production nurseries is that it identifies maintenance items that will reduce system downtime and will help to improve productivity and profitability. Conducting a system analysis demonstrates to regulatory authorities that a responsible approach is being taken to water management, and impacts to the environment are being minimised. As an industry, it is imperative that information gained from irrigation system audits is readily available, so that nurseries have continued access to water.
