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.

A new school required this low flow package lift station in order to handle the neighborhood’s increased flow of municipal wastewater. Ebara vortex pumps in a duplex configuration are used for deep well pumping. They are explosion proof in order to meet the Class 1, Division 1 hazardous location requirements. A below-grade valve vault provides easy access to system plug valves, shut-off valves, and swing check valves. An outdoor UL listed control panel manages the lift station’s mechanical and electrical systems with float controls for liquid level-sensing and a basic alarm.

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.

When a public high school decommissioned an existing septic system, a replacement package lift station was needed to handle the sewage from the campus. Tsurumi submersible cutter pumps were used to pass most solids and cut larger solids into passable sizes (about 1¼” diameter). The pumps also meet the low flow low head requirements for the new 3” PVC force main. The manhole and below grade valve vault are traffic rated. The outdoor control panel was mounted on the existing support structure for the decommissioned septic.
