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.

An upscale beachside community in California needed this medium flow wastewater lift station to replace septic systems used at each home. To meet the requirements of the beachside location, this system includes Ameron T-Lock PVC lining on both a precast concrete sump and emergency overflow basin. A below-grade vault contains the system’s valve and meter assemblies. Large bluffs between the beach and the city treatment plant required super-high head submersible pumps. The system electrical controls comprise redundant controls and level sensing with SCADA integration.

This industrial pumping system was designed to handle medium flows of process wastewater created from cleaning cycles at the Merck Animal Health facility. The wastewater was specified with highly variable pH conditions, so the pumping system was designed with a double-wall fiberglass sump with leak detection. All of the submersible components in the well were constructed of stainless steel, including the Tsurumi duplex submersible pumps. The pumping system electrical controls comprised a UL listed panel with SCADA integration.

The construction of this new hospital required a package lift station system to handle medium flows of wastewater. This comprehensive system includes five below-grade vaults. Four concrete vaults comprise the valve vault, metering vault, odor control vault, and wet well. Additionally, an 18,000 gallon fiberglass vault was included as an overflow tank for emergency backup storage. Tsurumi cutter pumps in a duplex configuration start and stop pumping cycles on level with primary and backup float controls. The outdoor UL listed control panel controls the total operation of the system valves, meters, sensors, pumps, and additional electrical.
