Recent Heavy Rains: Ensure Your Sump Pump Is Draining Outside Your Home
The city of Sioux Falls has received significant rain, and Public Works is reminding homeowners to ensure sump pumps are draining outside their homes.
The sanitary sewer system is taking on extra flow, resulting in high flows at the wastewater treatment plant. The system is designed to convey only water from toilets, sinks, showers, dishwashers, and laundry machines. Public Works is actively trying to identify sources of inflow into the system.
“Improperly discharging sump pumps into the sanitary sewer system can result in sewage backups into homes,” says Mark Cotter, Director of Public Works. “It is illegal to attach sump pumps to floor drains or otherwise connect them to the City’s sanitary sewer system.”
Sump pumps, which remove groundwater from homes and businesses, should be discharged into yards or streets. Properly discharged water will enter the storm drainage system, where pipes are designed to handle the larger water flows created by sump pumps and rain runoff. The storm drainage system includes the City’s curb and gutter, street inlets, large-diameter drainage pipes, drainage ditches, and detention ponds, which ultimately discharge to the Big Sioux River.
