Safe Water for the World

A trip to Kwa Zulu, Natal, South Africa in 1988, and another to the Island of Mindanao, Philippines in 1989 to identify opportunities to provide sufficient, safe drinking water to rural communities lead to the development of the BioSand Water Filter. All the academic and professional experience of David Manz, P.Eng., lead him to hypothesize that a variation in the design of a one hundred and fifty-year-old technology would be a solution to treating water in households in developing countries to a quality safe to drink.

In 1991, with a $75 budget and as an enthusiastic fourth year civil engineering student, it was demonstrated that the idea would work and the BioSand Water Filter was born. It needed a champion and David decided that he would take on this role. This was his opportunity to make a difference. Successful demonstrations in Central and South America, support from the Department of Civil Engineering and the Division of International Development of the University of Calgary provided confirmation of concept and first implementable designs. The filter was found to be effective, accepted and sustainable. The filter design and use were available for free and demand for training exploded. A company was formed in 1995 to bring the technology to rural Canada. Some of the profits supported the development and dissemination of the humanitarian program.

In 2000, David brought his teaching and research program at the University of Calgary to closure to pursue business fulltime.Then the adventure really started. 25 years later, there are more than two million filters in operation worldwide with thousands being constructed every week. This year, the filter technology has evolved to meet water treatment needs of the billions of people in all households and communities, urban and rural, poor, or wealthy around the world. The adventure continues.

About the Presenter

Dave Manz, P.Eng.Dave Manz, P.Eng., has received numerous awards of recognition for the development and dissemination of the BioSand Water Filter including the Project Achievement Award in 1996 from The Association of Professional Engineers, Geologists, and Geophysicists of Alberta; the President's Award for Community Member in 2003 from the University of Calgary, and an Alberta Emerald Foundation award in 2009. the 2010 C.J. Mackenzie Distinguished Graduate Lecturer and nominated for the Engineering Wall of Distinction, College of Engineering, University of Saskatchewan, and in 2011 the Alberta Science and Technology Leadership Foundation, ASTech Award Winner, Social Impact. This January he was selected as one the 20 most compelling Calgarians (City of Calgary) for 2018 by the Calgary Herald (newspaper) editorial staff. He has been a member of APEGA since 1974.

He is best known for the BioSand Water Filter he invented in 1990 while an associate professor in the Department of Civil Engineering at the University of Calgary. This filter is now in use in virtually every developing country in the world, distributed by literally hundreds of Non-Governmental Organizations he trained directly and who had subsequently trained others in their proper construction of the filter and its use. It is estimated that there are more than two million of these filters in operation with several hundreds being produced each day. He continues his support for these humanitarian initiatives.

Dave was born in 1947 and raised on half-section dry land farm fifty miles northeast of Regina. He completed his Bachelor of Science in Agricultural Engineering at the University of Saskatchewan in 1972, followed by his Masters degree in Hydrology in 1974. He obtained his doctorate in Water Resources Engineering from the University of Alberta in 1985. He has been a flood forecasting engineer with the Government of Alberta, instructor at Lethbridge Community College, faculty member in the Department of Civil Engineering at the University of Calgary, engineering consultant in water resources engineering, irrigation engineering and environmental engineering, inventor of water treatment systems for developing and developed countries, inventor of treatment system to recycle frack flowback, and is an entrepreneur, actively inventing, manufacturing and marketing new filter products.
