A break in a sewer line on the north side of Coralville has caused an ongoing discharge of untreated wastewater.
The water has been going into a storm water basin, then Muddy Creek, then into the Iowa River according to the Iowa Department of Natural Resources.
The break was reported to the city about 3:30 Wednesday afternoon after someone saw sewage coming out of a manhole. The city was assessing damage to a lift station “to determine the extent and timing of repairs.”
Officials don’t know when the discharge began. Normally about 321,000 gallons of untreated wastewater go through the pump station each day.
