Topeka's water department is monitoring the Kansas River for E. coli after a weekend sewage spill.
The city of Topeka says the sanitary sewer bypass pumping station went down over the weekend, discharging waste into the river.
Most of the sewage spilled into the Kansas River overnight Sunday. It's unclear how much sewage spilled or what caused the failure.
The city's Water Pollution Control Division is monitoring the river for E. coli concentrations, and will continue to monitor the water until counts show normal levels.
The city says the Kansas Department of Health and Environment, and the Lawrence, Olathe, and WaterOne Utility water treatment plants were notified Monday of the breach.
