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.

In addition to the information above, attendees will learn

  • Rainwater quality: typical range of waterborne contaminants
  • Construction materials: roofing, water conveying materials, storage tankage, and treatment equipment
  • System design options: above/below ground storage, outdoor/indoor usag
  • Usage options
  • Treatment technologies
  • Regulatory issues

The Presenter: Peter Cartwright

Peter Cartwright entered the water purification and wastewater treatment industry in 1974, and has had his own consulting engineering firm since 1980.

He has a degree in Chemical Engineering from the University of Minnesota (1961) and is a registered Professional Engineer in that state.

Peter has provided consulting services to more than 250 clients globally. He has authored in excess of 150 articles, written several book chapters, presented over 160 lectures in conferences around the world, and is the recipient of several patents.
