Water and Public Health

Fellows and faculty prepare for a tour of the Milwaukee Metropolitan Sewerage District facility
On World Water Day 2011, Fellows and faculty celebrated appropriately by spending the monthly meeting focusing on the connections between water and public health. The day began with a discussion with the Communications Manager at the Milwaukee wastewater treatment plant.
We learned:
  • How wastewater is cleaned
  • How wastewater byproducts are transformed into Milorganite, a fertilizer
  • How combined sewer overflows happen
  • Details on Milwaukee's Deep Tunnel, which can store over 400 million gallons of water during times of heavy rain
  • About the challenges of treating stormwater
Joyce Harms, MMSD's Communications and Community Relations Manager, describes the current water storage volumes of the plant's systems

After learning about wastewater treatment, the group headed over to the Great Lakes WATER Institute to meet with Dr. Sandra McLellan. She presented her research on bacterial indicators of fecal pollution. That is, she figures out how to tell if places like beaches have traces of human waste--a major transmitter of disease.
