The McCormick Woods northern development purchased this lift station configured to meet the medium flow requirements for municipal sewage. This package lift station was needed because of the uneven terrain surrounding the development. Two submersible solids handling pumps pump to a below-grade valve assembly containing the lift station valves and access ports. A sheltered PLC control panel utilizes a pressure transducer for primary liquid level-sensing with backup float controls. The panel is tied to an onsite generator for emergency backup power.

A large neighborhood received these two lift stations that were designed to handle medium sewage flow requirements. The submersible solids-handling pumps in duplex configurations were specified to handle influent from three inlet lines from different sections of the neighborhood. The below-grade valve assemblies hold the system operation valves, bypass pumping ports, and shut-off valves. The outdoor UL listed control panels utilize pressure transducers and redundant float controls for liquid level-sensing; basic alarms were included for communications.

This wastewater lift station was required to hand medium sewage flows from a development neighborhood by Smith River Rancheria, the governing body of the Tolowa Dee-ni’ Tribe. Two Goulds Water Technology 2 hp grinder pumps were used to meet the high head requirements for over 3,000 ft of force main. A owner-supplied control building contains the control panel and an permanent onsite Cummins generator for backup power. A Mercoid pressure transducer provides primary level-sensing controls with Dwyer floats for backup.

This medium flow sewage lift station was designed for a new development to meet the Sammamish Plateau Water and Sewer District lift station design standards. These standards specify a PLC controller with touchscreen HMI, SCADA options, a precast concrete valve vault, wet well, meter vault, and duplex submersible pumps. In addition to these design standards, this lift station needed to tie-in to an existing force main owned by the District. Romtec Utilities provided the tie-in force main designs and calculations as well as VFDs (variable frequency drives) to match the changing flow and pressure conditions of the existing force main.
