This package lift station was designed to meet the medium wastewater flows of this California prison. Solids-handling pumps in a duplex configuration are protected from cascading influent by a drop bowl. The liquid level-sensing is controlled by a pressure transducer and a float in used for emergency backup. A below-grade valve assembly holds the system’s valves, flow meters, and pressure gauges. An outdoor PLC panel with a basic alarm and an added input for a radio modem comprise the systems controls.
