Real-time Control of Stormwater Management Systems

Earlier this week the Notre Dame Journal on Emerging Technologies published Overcoming Legal and Institutional Barriers to the Implementation of Innovative Environmental Technologies, a paper I co-authored with Dr. Walter McDonald of the Department of Civil, Construction and Environmental Engineering (CCEE) in Marquette’s College of Engineering; Stormwater flowing into a grateJoe Naughton, a 2020 Sea Grant Knauss Fellow at the National Oceanic and Atmospheric Administration; and Hannah Hathaway, a member of the Law School’s Class of 2020. Another faculty colleague, Dr. Tony Parolari of the CCEE department, participated in the underlying research grant that resulted in the paper. This kind of work is part of our core mission: the Marquette University Water Law and Policy Initiative seeks, among other things, to employ an interdisciplinary approach, and to pursue opportunities for information exchange and collaboration within and outside Marquette University.

The following excerpt describes the work. The full article is freely available at the above link.

Communities in the United States face growing challenges to effective stormwater management as a result of aging infrastructure, increasing urbanization, changing climate, and shrinking budgets, among other factors.  These changes have increasingly stressed existing “static” stormwater management systems such as pipe networks, retention ponds, and detention ponds, that are intended simply to convey storm flows to nearby receiving waters without regard to overall system conditions.

Dealing with these stressors may require innovative solutions such as real time control (RTC) or “dynamic” stormwater management systems.

COVID-19 and Water

Without doubt, times are tough. The seemingly inexorable spread of the COVID-19 pandemic has left many of us desperate for good news. And make no mistake, there is some out there. First, it’s heartening to see the An image of the coronavirusincreased appreciation for those in the public health sector, and also for the unsung heroes of the war against COVID-19: grocery store personnel, garbage collectors, truckers, janitors, pharmacy clerks, postal workers, package deliverers, and others who we now realize are truly essential to a functioning modern society. Let me add one more group of people to that list: utility workers who keep our power on, our access to the internet active, and our clean water flowing. For example, to ensure a reliable water supply, some water treatment professionals are “sheltering in place” at a water treatment facility for the next three weeks. Others, right here in Wisconsin, are working twelve hour shifts in complete isolation to ensure that critical machinery remains operational.

That leads me to my second bit of good news: according to the Environmental Protection Agency (EPA) and the Centers for Disease Control (CDC), our water supply is not threatened by COVID-19. Like most viruses, it is “particularly susceptible to disinfection,” a standard process at wastewater treatment plants. It seems appropriate to be grateful for this, given that Sunday was World Water Day. Imagine how terrible this crisis would become if we could not trust our drinking water.

A Retrospective on the “Year of Clean Drinking Water”

2019 was a memorable year for those interested in Wisconsin’s water resources. During his January 2019 “State of the State” address, Governor Tony Evers declared it the “Year of Clean Drinking Water in Wisconsin,” making water a primary focus of his first year in office. Around the same time, Assembly Speaker Robin Vos announced the creation of a water quality task force to study water contamination issues. Shortly thereafter, I An exterior photo of the Wisconsin State Capitol.wrote a post describing a shorthand “top ten” list of issues for the administration and the task force to consider. In no particular order, my list included lead laterals, PFAS and other emerging contaminants, nutrient pollution, groundwater contamination and private wells, Great Lakes diversions, CAFO regulation, the DNR, infrastructure, high capacity wells and groundwater drawdown, and wetlands protection.

But now 2020 has arrived. What were the tangible results of the “Year of Clean Drinking Water”? Many promising efforts are underway and the state has made significant progress in some areas, but much remains to be done. The Governor’s declaration and the Speaker’s task force brought much needed public attention to water quality issues, but it would be a shame if that intense focus fades with the turning of the calendar. Governor Evers recognizes this, admitting in a recent interview that he knows the work will take much more than a year. And he expects Wisconsinites to support it in the longer term: “People like to have clean drinking water,” he said. “Who doesn’t want it? Who doesn’t need it?” Yet in his 2020 “State of the State” address Evers mentioned water only once, a late reference to “getting PFAS out of our water” as part of a list of things yet to be accomplished.

Here are the specifics of what happened last year:
