City of South Bend Combined Sewer System Embedded Sensor Monitoring System Phase II CSO 025 North Shore and Lafayette Background The primary objective of combined sewer overflow (CSO) control for South Bend is to eliminate dry weather overflows, reduce the frequency and quantity of wet weather CSO events that discharge to the St. Joseph River, and maximize flow to the wastewater treatment plant. For this project, ten (10) CSO diversion structures have been prioritized for upgrade and improvements that include actuated regulator valves on the CSO throttle pipes. The valves are integrated through a computerized CSONet system that will modulate the valves to the best utilize the City's combined sewer system for each particular storm event. The system will regulate flow to the interceptor much like traffic signals regulate traffic flow on streets. The result is that, instead of being discharged to the river as CSO, more flow will reach the treatment plant and water quality impact of CSOs in the St. Joseph River will be reduced. CSO 025 Location — North Shore Historical District One site is located in the North Shore Local Historic District at the intersection of North Shore and Lafayette. Most of the work for this project will be below ground however we will need to install a control cabinet and a small radio antenna along the south side of North Shore. The control cabinet will be made out of stainless steel and will be located at the intersection of Lafayette and North Shore on the south side. The location of the cabinet is shown on the site plan. There is an existing bush that we would used to hide the cabinet. This control cabinet will housie the telemetry and control equipment for the pinch valve that will be installed below the street. This site would was selected because of the existing vegetation that could be used to obscure the view of the control cabinet. This bid opening for this project is scheduled for August 24, 2009.
