V.C. Summer Nuclear Station

V.C. Summer Nuclear Station|Jenkinsville, SC|35 GPM - 33.6' TDH

jweddell5gpm - 50gpm, Eastern, HRSG Blowdown, HRSG Pumping, Power Generation, Process Water

This package lift station was configured to handle low flows of industrial process water used for nuclear power generation. This lift station was one of the earliest systems to be installed during the construction of two new reactors at the plant. Submersible grinder pumps in a duplex configuration and a below grade valve assembly comprise the principal mechanical operations of the station. An outdoor control panel utilizes floats for primary liquid level-sensing, and an autodialer for communications and alarm notification.

Tennessee Valley Authority at Shawnee Fossil Plant

TVA Power Plant|West Paducah, KY|50 GPM - 67.7' TDH

jweddell50gpm - 100gpm, Central, Industrial, Industrial Water, Power Generation, Wastewater, Wastewater Featured

This industrial power plant needed a package lift station to meet the requirements for municipal wastewater. The 23-foot-deep sump holds duplex Goulds submersible sewage pumps specified to meet the 50 gpm maximum flow requirements. A precast concrete valve vault contains the system valves and a force main junction. Both the below-grade wet well and valve vault are pedestrian rated. Liquid level-sensing controls are a pressure transducer and floats for backup. The outdoor control panel includes a receptacle for an owner supplied onsite generator.

PG&E Power Plant|Colusa, CA|300 GPM - 23' TDH

jweddell300gpm - 500gpm, Equipment Washdown, Industrial, Industrial Water, Pacific, Power Generation, Stormwater, Stormwater Runoff, Wastewater

These three package lift stations were designed to meet medium flows of industrial process water with added low flows of industrial stormwater and wastewater. Submersible centrifugal pumps in a duplex configuration were specified to meet the peak flows and water chemistry identified for each pump station. UL listed control panels with floats for liquid level-sensing and basic alarms comprise the system controls for the lift stations. These packaged lift stations were integrated into stormwater, processing, and wastewater plans for the new construction of the Colusa Generating Station.

Geothermal Power Facility in Nicaragua

Geothermal Power Plant|San Jacinto, Nicaragua|100 GPM - 24.9' TDH

jweddell50gpm - 100gpm, Power Generation, Wastewater

A commercially owned geothermal power facility in Nicaragua purchased this package lift station to meet its medium wastewater flows. Shipping the major components for this system required precise documentation and plans. Duplex submersible chopper pumps, in-well check valves, and plug valves with valve cans are some of the major below grade components of this system. The outdoor UL listed control panel utilizes floats for liquid level-sensing and includes an autodialer for communication. The complete Romtec Utilities package system was owner-installed as part of its phase I development.

Culbertson Power Plant|Culbertson, CA|100 GPM - 25' TDH

jweddell50gpm - 100gpm, HRSG Blowdown, HRSG Pumping, Industrial, Industrial Water, Mountain, Power Generation, Process Water, Wastewater

This power generation facility installed a package lift station designed for medium sewage flows of industrial wastewater. To protect the submersible solids-handling pumps, an inlet line deflector panel was included in the design. The wet well was protected from off-gassing and corrosion by an interlocking fiberglass lining. Conductive probes are used for primary and backup liquid level-sensing with an outdoor UL listed control panel. The panel is outfitted with a basic alarm and an autodialer for telecommunications.
