GLRC Celebrates World Water Day
The Great Lakes Research Center at Michigan Technological University has several events planned to commemorate World Water Day. While officially celebrated on Wednesday, March 22, there will be events throughout the week of March 20th to focus on the issue of clean water.
The theme of this year’s World Water Day is “Wastewater.” Globally, 80 percent of all wastewater flows back to nature without being treated or reused. Not only does this pollute the environment, but valuable nutrients and potentially recoverable materials are lost. Daisuke Minakata from Civil and Environmental Engineering says “Wastewater is no longer a collection of liquid and solid wastes but our valuable resource so that we can create potable water from wastewater with advanced treatment technologies and recover valuable materials and even energy from waste. In this sense we no longer call it a wastewater treatment plant but water resource recovery facility.”
Reuse of wastewater is the theme of Michigan Tech’s World Water Day Keynote lecture. George Tchobanoglous, professor emeritus in the Department of Civil and Environmental Engineering at the University of California, Davis will present “Planned Potable Reuse: The Last Frontier.” His talk will take place at 5 p.m. Tuesday, March 21 in Dow 641.
The nation’s water supplies are derived from a variety of sources, including local and imported surface water, groundwater and other sources. Public water supplies in many regions are becoming stressed because of population growth, urbanization, the growth of megacities, cyclical droughts and climate change.
