DeWitt, Iowa — About 150,000 gallons of untreated wastewater were discharged into Silver Creek, according to the Iowa Department of Natural Resources.
The problem was discovered around 8 a.m. Wednesday, November 9, 2016 by city staff. They were able to remove the grease and resume normal operations within 20 minutes. That work stopped the wastewater discharge.
This report came the same morning as another wastewater report in Lake City. Staff there found that the main pumping station at a wastewater treatment facility had flooded. The discharge stemmed from an electrical failure, and leaked 101 gallons per minute, according to the DNR.
The city was working to fix the issue, and divert wastewater into the city lagoon. The situation in Lake City is still being monitored.
