The idea of using rain water doesn’t only make sense for the environment; it can also save money. Everyone agrees that clean water is a precious resource. However, it is often taken for granted. The businesses and communities that invest in water-wise practices are more likely to thrive as the availability of clean water becomes more scarce. Rainfall harvesting systems are designed to collect and store rain water to be used when treatment to drinking water standards is not needed.
Applications may include washing vehicles or clothing, flushing toilets, landscape irrigation, fire suppression or water for boilers and chillers in large HVAC systems. By meeting more water needs with rain, less demand is placed on increasing water treatment plants and infrastructure. In addition to using water more wisely, capturing rainfall will reduce stormwater runoff.
