SWIMMING POOL WATER EVAPORATION STUDY
Results from a study in response to the California drought showed that certain pool covers can significantly reduce water loss due to evaporation. The National Pool Industry Research Center compared water-loss in pools with solid track covers, bubble covers(aka Solar Blankets),solar disks, foam covers, and liquid evaporation suppressants. Evaporation is a major factor in water loss and, conversely, water savings, the researchers said. The 3 highest performing covers were foam, showing 95.9 percent efficiency, BUBBLE COVERS(aka Solar Blankets) at 94.9 percent efficiency, and solid track covers at 93.9 percent. In the mid-range were solar disks, at 50.1 percent. The liquid evaporation suppressants rated lowest, between 14.4 and 15.8 percent. It seems that covers are the best way to contribute to water-conservation. Call Rich for more information at: 609-313-0300
