FDL Treatment Facility Handles Wastewater During Big Rain

The Fond du Lac area got nearly 4 inches of rain Wednesday night. The Fond du Lac Regional Wastewater Treatment and Resource Recovery Facility keeps track of rain and snowfall. Superintendent Autumn Fisher says the peak flows of water they treated that night were more than 7 times their normal level. They usually treat about 8 million gallons of wastewater a day, but at their peak flow that night the flow was at a rate of 58 millions gallons a day. They were busy with the high flows. There were some alarm calls out and crews responded to stay ahead of it. The facility recorded 3.95 inches of rain from 7:30 to 11:45 that night. She says despite the heavy rain they did not have to bypass the treatment system or blend wastewater. Police got nearly 30 reports of flooded streets that evening.
