EXHIBIT A Work Order Number 34 Reuse Control Panel Replacement at South County Wastewater Treatment Plant PROJECT UNDERSTANDING Indian River County Utilities (IRCU) owns the South County Wastewater Treatment Facility (SCWWTF), a 2 MGD AADF facility that operates under FDEP permit FLA010435-005-DWIP-NR. The SCWWTF disposes of treated effluent via six on-site Rapid Infiltration Basins (RIBS) and off-site reuse customers. The reuse system is served through the on-site pump station, which consists of three (3) 100 -hp vertical turbine pumps and a subgrade wet well. The station operates similar to a conventional lift station (ladder logic), where pumps are called to run/stop via mercury switch floats. The control panel for the lift station is located outside on a separate pad, directly adjacent to the wet well. The starters for the 100 -hp pumps are direct online (DOL or "across the line") motor starters. Power and signal wiring from the reuse station are provided through an existing electrical building located near the pump station. The control panel is antiquated and rests on a concrete pad that had differential settlement, resulting in undermined concrete slab and leaning control panel. Further failure of this slab may result in failure of the control panel and should be addressed immediately. Furthermore, the existing motor starters are inadequate for the reuse system and a more modernized approach to controlling pump operation should be explored to mitigate the frequent instances of water hammer experienced at the station. It is our understanding IRCU desires to upgrade the following components of the reuse pump station: • Demolish DOL starters and replace with Variable Frequency Drives (VFDs) to reduce energy consumption and mitigate water hammer issues • Locate the VFDs within the existing electrical building and provide local HOA switch and electrical disconnect near pumps • Provide continuous analog measurement of wet well level and discharge pressure Kimley-Horn ("Consultant") will utilize the services of C&W Engineering to perform the electrical engineering portions of this project.
