The overall goal of the study was to reduce water consumption in swine operations to mitigate impact on water resources and to reduce production costs. A comprehensive literature review was conducted to identify water conservation strategies that can be adopted in swine operations, followed by a benchmark survey to determine current rate of water use in hog production operations in Saskatchewan. The literature search showed that limited published work on innovative water conservation strategies that can lead to significant reduction in water use in swine operations is available. The benchmark survey revealed that there is a wide range of water usage and costs of water incurred per pig among barns which indicated significant opportunities to improve water use efficiency and to reduce costs. Animal drinking and cleaning were identified from the literature and the survey as the top two areas where potential water savings can be achieved. Evaluation of selected conservation measures involving animal drinkers and different cleaning procedures were done at the barn facility of Prairie Swine Centre in Saskatoon. Results indicated that relative to conventional nipple drinkers, the use of a drinking trough with side panel and constant water level achieved about 60% less water wastage without adversely affecting pig performance. High pressure washing using a conventional nozzle led to lesser time and water consumption during the cleaning process. Further studies involving other stages of production are needed in order to provide a more comprehensive evaluation of the performance of these water conservation measures in swine barns.
