ABCs of Graywater Reuse and Recovery

As the developed world slowly realizes the benefits of water conservation and reuse, the role of decentralized (source) wastewater treatment and reuse is gathering momentum. One of the key outcomes of this mindset is graywater reuse: the water leaving lavoratory sinks, showers, baths and washing machines. 

This one-hour webinar defines the chemistry of these streams and potential applications for the recovered water. It identifies treatment technologies as a function of application requirements and discusses engineering design details. The current regulation environment will be addressed, as well as future developments. NSF testing protocol which qualify treatment systems are described in detail. 

The plumbing engineer and designer will gain knowledge to facilitate the design and construction of graywater systems, and will also develop an understanding of the potential applications for graywater reuse which dictate the required treatment technologies. 


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. He also provides extensive expert witness testimony.

He is a founding member of the Technical Review Committee for Water Conditioning & Purification magazine, on the Editorial Advisory Committee for Water and Wastewater International magazine, the Reader Advisory Board for Processing Magazine, and the Editorial Advisory Board of Filtration News magazine. A peer reviewer for the Journal of Membrane Science, he is also on the faculty of the University of Wisconsin-Madison College of Engineering annual course, “Process Piping Systems Design and Operation."

Peter is a recipient of both the Award of Merit and Lifetime Member Award from the Water Quality Association, and is the Technical Consultant for the Canadian Water Quality Association.
