GRIMES, Iowa (AP) — Officials say there's an ongoing discharge of wastewater going into a creek in central Iowa.
The state Department of Natural Resources says the discharge developed while officials with the city of Grimes were replacing a pump at a lift station Wednesday afternoon.
Officials say when two pumps failed at the same location, they hauled incoming wastewater to the city's sewage treatment plant. But the city could not keep up with the incoming flow of wastewater.
The DNR says an unknown but small amount of wastewater is "occasionally" discharging into an unnamed creek. That creek flows to the lake at Cutty's Des Moines Camping Club, then to North Walnut Creek.
Officials are working to repair the lift station by Wednesday night. Additional information was not released.
