• Cummins Flood Risk Reduction

  • Columbus, Indiana Cummins Technical Center

    The scope of the flood risk reduction project was to manage both stormwater runoff and water table level to prevent flooding of the Cummins Technical Center and associated buildings. During previous rain events, significant damage had occurred to buildings and equipment.

    Challenges

    The project required the control panels to house a 15kva mini-power zone lighting panel as well as an automatic transfer switch. These large items required a custom enclosure to be designed and manufactured. The three enclosures had to be powder coated with a color that matched the Cummins paint colors. These requirements required a long lead time to complete the custom enclosure, but could not affect the project dateline.

    Solution

    Toric’s engineers’ design helped to reduce the lead time, and the panel shop’s commitment to working overtime to manufacture the enclosure, enabled us to meet the project schedule. Two control panels, Pump Station 1 & 2, were provided to help control stormwater runoff from the property. Pump Station 1, a five pump control panel, controls the runoff from the rear area of the property and Pump Station 2, a two pump control panel, controls the runoff from the front area. Each pump has START and STOP level setpoints that are adjustable in the PLC via a local touchscreen operator interface. Each control panel is equipped with an automatic transfer switch that activates a standby generator in the event of a power failure. Control status and alarms are communicated to the existing plant SCADA system. The water table level is controlled by a Dewatering panel connected to two large submersible well pumps at different locations on the technical center campus. The pumps are located at a depth of approximately 90 feet. The water table level is obtained from each well and an additional monitoring well. The START and STOP setpoints are adjustable within the PLC, via the operator panel located on a swing-out panel within the enclosure. The speed of each well pump, as well as the acceleration and deceleration time of the pump, is controlled via a Variable Frequency Drive. This enclosure is also equipped with an automatic transfer switch that activates a dedicated standby generator in the event of a power outage.
