The City of Sioux Falls just issued a press release to limit water usage in the city.

This is an emergency message from Public Works to inform you that we are experiencing above normal flows in the sanitary sewer system. The high flows are placing stress on the Sanitary Sewer System that is unsustainable. We ask that you limit the water usage in your home until further notice and ensure there are no sump pumps discharging to the Sanitary Sewer.
