REAL-TIME COMPUTER CONTROL OF URBAN RUNOFF

COMPUTER CONTROL AND MODERNIZATION OF COMBINED SEWER OVERFLOW REGULATORS AND AN URBAN HYDROLOGY HYDRAULIC MATHEMATICAL MODEL ARE DESCRIBED. THE SYSTEM HAS BEEN INSTALLED TO CONTROL THE MINNEAPOLIS-ST. PAUL SEWER SYSTEM DURING STORMWATER RUNOFF TO IMPROVE THE UTILIZATION OF THE EXISTING INTERCEPTOR SEWERS. KEY STORMWATER REGULATORS WERE MODIFIED TO PROVIDE REMOTE CONTROL OF HYDRAULICALLY OPERATED GATES AND INFLATABLE DAMS. TRUNK SEWER AND INTERCEPTOR SEWER LEVEL MONITORING STATIONS AND RAIN GAGES ARE USED AS INPUT TO A MATHEMATICAL MODEL CONSISTING OF: (1) RAINFALL-RUNOFF MODEL; (2) STORMWATER DIVERSION MODEL; AND (3) FLOOD ROUTING IN THE INTERCEPTOR SEWER. A HIGH DENSITY RIVER QUALITY MONITORING SYSTEM HAS BEEN INSTALLED TO DETERMINE QUALITY EFFECTS OF RUNOFF EVENTS AND TO EVALUATE THE EFFECTIVENESS OF THE CONTROL SYSTEM. AUTOMATIC SAMPLING AND AUTOMATED WET CHEMICAL ANALYSIS OF WASTEWATER HAVE BEEN USED TO IDENTIFY HOURLY QUALITY VARIATIONS IN THE WASTEWATER. /AUTHOR/
