The California Pool and Spa Association (CPSA) is pleased to announce a landmark study that will provide much-needed data on how to mitigate evaporation water loss in swimming pools. Sponsored by a wide range of industry associations including the CPSA, the National Plasterers Council, the Association of Pool & Spa Professionals, and the Independent Pool and Spa Service Association, the study will focus on measuring the water savings that can be achieved by different types of pool covers available to consumers. It will be conducted at the Cal Poly National Pool Industry Research Center (NPIRC) on the California Polytechnic State University campus in San Luis Obispo throughout the months of July and August.
While it has been conclusively proven that pools use less water than the lawns they typically replace, there are as of yet no exact figures on how much water is saved with the installation of various types of pool covers. Estimates range from 50-90% in savings, an issue that is complicated even further when all of the variations in cover design and style are considered. This study aims to end that uncertainty by examining a pool’s water usage with many different types of covers, accurately measuring and tracking the differences in each. This will include measuring the water levels of eight different pools at the NPIRC for a full sixty days, taking into account such factors as climate conditions, wind, and rainfall during the study.
Swimming pool owners seem to understand that pool covers are one of the best methods to save water. However, consumers have not been provided accurate information on the performance of the various systems. In addition to the traditional air bubble covers, there are different kinds of permanent covers, solar rings and solar squares, and now a range of liquid pool covers that provide systematic water savings while maintaining the landscape features of the pool. This study seeks to more clearly inform the pool and spa industry on the exact numbers of evaporation and water loss, as well as empower pool owners to make the best choice to protect and maintain their investment.
In this time of drought and water scarcity, it is more important than ever to fully understand the entirety of a pool’s water usage, and actively look for new and innovative ways to lower a pool’s already minimal water footprint. In our meetings with water districts and cities throughout California, CPSA has repeatedly recommended the use of pool covers as a means for pool owners to reduce their water usage while still being allowed to fill and maintain their pools. However some cities have expressed the desire for more concrete information and data on this particular subject. With this study in hand, we will have all the information we need to show cities and water districts that pools are a responsible part of any water savings plan.
This study is a crucial part of CPSA’s Let’s Pool Together campaign. It will help demonstrate to water management professionals throughout the state that pools and spas can contribute to the water saving effort, and we are grateful to all those who have come together to make it a reality. Stay tuned for more information.
