Reducing the amount of water used for landscape irrigation continues to be a major issue for municipalities throughout Texas and the nation. A survey of monthly water use for 2000 through 2002 for 800 residences of similar size and appraised value in College Station, Texas indicated that average peak water consumption increased as much as 3.3 fold during the summer compared to the months of December, January, and February. Individual monthly water budgets were derived for each residence based on landscape size, PET, and a landscape irrigation coefficient (Lc). Monthly water budgets were compared with actual monthly water used. These comparisons demonstrated seasonal water use patterns as well as the potential for very large reductions in landscape water use. In 2000, 2001, and 2002, an average of 347, 410, and 476 households, respectively, applied irrigation water in excess of PET. Had these households irrigated during May through October at 100% of PET, which is equivalent to an Lc of 1.0, total predicted annual water savings for these households would have been 74, 104, and 85 acre feet in 2000, 2001, and 2002. Had irrigation been applied using an Lc of 0.7, the estimated savings would have totaled 92, 111, and 100 acre-feet during the same period. The households that used excess water for landscape irrigation could have reduced landscape irrigation amounts by an average of 48% annually and still have sustained an attractive landscape. Thus, a significant opportunity exists to reduce home consumer water use through more efficient landscape irrigation management.
