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 new development for a commercial park needed this wastewater lift station to connect the development to the municipal sewer system. Submersible centrifugal pumps in a duplex configuration were engineered to meet the medium flow high head conditions of the force main. This system needs to pump at a predefined flow rate in order to achieve the minimum force to reach the existing municipal sewer lines. The lift station control panel is a UL listed panel with redundant float controls wired for intrinsically safe use.

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 package lift station is part of a sustained plan to expand the collection system of a large sewage treatment plant completed in 1999. The medium flow is handled by submersible solids handling pumps in a duplex configuration. A pigging port, plug valve, shut off valve, mechanical indicator, back flow actuator, and swing check valve are all contained in a below-grade valve vault. An outdoor control panel includes an autodialer for communications, conductive probes for level sensing, and an intrinsically safe barrier for in-well electrical controls.

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.
