Cal Poly Evaporation Study – Effectiveness of Pool Covers to Reduce Evaporation from Swimming Pools
Water is one of the earth’s most precious resources and is fundamental to quality of life, economic development, and the environment. However, drivers such as population growth, natural variability and change in climate, and urbanization are making water availability increasingly uncertain (Schnoor, 2008). In California, for example, the persistent and severe drought the state faced during the last four years has called for unprecedented measures including Executive Order from Governor Brown mandating 25 percent reduction in potable urban water use. In response, cities and water management agencies across the state have enforced water conservation measures to meet the mandate.
Torching: An Inexpensive Way to Eliminate Tough Pool Stains
When a plaster pool becomes severely discolored or stained, inexpensive remedies to fix the problem are limited, unless the pool professional is skilled in the process of torching. Torching can quickly remove a small water stain from plaster or a large discoloration that otherwise might require tearing out the pool surface and replacing it with a new one.
