Since late last year, the Perpetual Notion Machine’s Lincoln Tice has produced a series of shows related to water, from the lakes to groundwater. Tonight, Lincoln continues the trend by discussing the elements of storm water management. His guests are Ken Potter, Emeritus Professor in civil and environmental engineering at UW-Madison, and Greg Fries, a Principal Engineer in sanitary and storm sewers in the City of Madison Dept. of Engineering. It’s nice to have a city this close to 4 incredible lakes. But unfortunately, Madison was built replacing wetlands that help absorb extra water. And before that, humans altered the water table of the lakes and straightened most creeks, streams, and even rivers. This provides a lot of challenges when dealing with runoff and flood water. Ken and Greg describe what has been done, and what needs to be done, especially the possible flooding from increasingly heavy rainfall events that are likely to happen.
