Although three-fourths of the earth’s surface is covered with water, only a minute fraction of water is both readily available and of sufficient quality for human use, including irrigation. Interest in recycled water irrigation continues to increase as more and better-quality treated water becomes available. Water shortages and the rising cost of potable water motivate the wise use of recycled water as a valuable resource for irrigating golf courses, parks, athletic fields, and other landscape sites. This attractive to-the-point presentation summarizes the state of the science and practice today. PowerPoint presentation, 141 slides. 2013. CSSA. Item: B30479DW (download).
