a) Infrastructure to hydraulically disconnect Miramar Reservoir from the existing sedimentation basins at Miramar Water Treatment Plant (MWTP), allowing the basins to be fully drained such that Miramar Reservoir water does not back up into the basins (following the addition of Phase 1 Pure Water into Miramar Reservoir, which would raise the reservoir water level from 706 ft to 712 ft). b) Construction of a solids pump station that would ensure the ability of MWTP to discharge sedimentation basin residuals to the reservoir at all times via a pumps system regardless of reservoir level. Pump station work includes: i. Solids submersible pumps to pump sedimentation solids to Miramar Reservoir ii. Magnetic flowmeter to measure solids discharging to the Miramar Reservoir iii. 18" DIP to convey sedimentation basin solids (connection to existing Sedimentation Residuals (SRES) Pipeline) to Miramar Reservoir via pumped system iv. Pump Station wet well v. Flow Meter manhole structure vi. Plug valves, restrained flanged coupling adapters, and swing check valves, and appurtenances vii. Process control, instrumentation, communication and signals systems and connection to existing MWTP SCADA System
