As population growth and industrial and agricultural activities continue to stress the quality of the relatively fixed quantity of available water on this planet, the plumbing engineer is challenged to investigate and develop unique and practical water collection and reuse technologies. One such answer to this challenge is rainwater harvesting. This webinar will describe the chemistry of rainwater sources. It will detail the engineering design, materials of construction, treatment technologies, storage and distribution, and other aspects of rainwater harvesting. The professional plumbing engineer and designer will gain knowledge and understanding to facilitate the construction and implementation of this important water recovery process. As rainwater harvesting becomes more widely utilized, the knowledge gained from this presentation will enable the plumbing engineer, designer, and contractor to access this market.
