is an independent company that is dedicated to the commercialization of its proprietary forward osmosis technology. Forward Water was founded by GreenCentre Canada and is rooted on a platform technology discovered at Queen’s University in Kingston, Ontario. 

The global pressure to maintain and enhance supplies of fresh water is increasing. Forward Water’s technology can simultaneously reduce the volumes of challenging waste steams having extraordinarily high levels of dissolved salts while at the same time return fresh water for re-use or surface release. Not only this, but the entire process can be driven using relatively low energy inputs.

Currently, Forward Water utilizes a fully automated and scalable engineering skid, capable of treating cubic meters of feed sources from client-based streams. These high-confidence trials enable an array of process optimization conditions to be tested for client feedback. These results can be readily translated into robust equipment designs, leading to the deployment of larger-scale commercial pilot units. Currently, Forward Water is using the same methodology to construct its first field unit for pre- commercial trials.

Forward Water is focused on the large scale implementation of its technology in industrial waste water, oil and gas, mining, agriculture and ultimately municipal water supply and re-use market sectors.



Howie  has 20 years of experience commercializing new technologies at Xerox, Cabot Corp., E Ink, Natrix Separations and as former CTO of GreenCentre Canada. Commercialized high capacity high through-put membranes for bioprocessing as SVP of Natrix Separations which was recently acquired by Millipore-Sigma. Other Commercial Success’: E-paper at E-Ink and MIT start-up – invented and lead team to first commercial platform of e-paper used in e-readers today. Since 2015, Howie has been leading Forward Water to become a premier wastewater treatment solution. Howie is also an inventor of record on over 50 US patents and holds a PhD in chemistry from the University of Toronto.

Dr. Maddever received his Ph.D. in Materials Science Engineering from the University of Toronto. Since 1985 he has held senior executive management positions with technically based businesses in start-up, turnaround or acquisition situations where his skills at change management have brought considerable success in the commercialization of new technologies. His experience in both private and public companies, both domestically and internationally, spans a broad variety of industries, including bio- and advanced materials, precision manufacturing, recycling, waste to energy and medical devices. He holds a number of patents in several fields. He is a Fellow of the Canadian Academy of Engineering. In addition to his duties as COO of Forward Water, he is currently Portfolio Manager at Bioindustrial Innovation Canada, one of the major shareholders of Forward Water.

Leonard holds inventorship on 7 US patents.


Dr. Philip Jessop is a professor and Canada Research Chair of Green Chemistry at the Department of Chemistry, Queen’s University in Kingston, Canada. He also serves as the Technical Director of GreenCentre Canada and Executive Research Director at Forward Water Technologies. After his Ph.D. (British Columbia, 1991) and a postdoctoral appointment (Toronto, 1992), he was a contract researcher in Japan working for R. Noyori (Nobel Prize 2001).  As a professor at the University of California-Davis (1996-2003) and since then at Queen’s, he has studied green solvents and the chemistry of carbon dioxide. Distinctions include the NSERC Polanyi Award (2008), Killam Research Fellowship (2010), Canadian Green Chemistry & Engineering Award (2012), Eni Award (2013), Fellowship in the Royal Society of Canada (2013), a Canada Research Chair Tier 1 (2013 to 2020), and the NSERC Brockhouse Prize (2019). He serves as Chair of the Editorial Board for the journal Green Chemistry, has chaired three international conferences, and helped create GreenCentre Canada, a National Centre of Excellence for the commercialization of green chemistry technologies. Forward Water Technologies Inc. is a spin-off company based upon Dr. Jessop’s switchable solvents.
