Merck Animal Health|DeSoto, KS|100 GPM - 21' TDH

jweddell50gpm - 100gpm, Central, Corrosive/ Caustic Pumping, Industrial, Industrial Process Water featured, Pharmaceutical Waste

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.

Sutter Medical Center|Santa Rosa, CA|90 GPM - 25.1' TDH

jweddell50gpm - 100gpm, Hospitals, Odor Control, Pacific, Wastewater

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.

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.

US Naval Base|Djibouti, North Africa|100 GPM - 20' TDH

jweddell50gpm - 100gpm, Military Installations, Wastewater

This package lift station was the perfect solution for installing an American-made system at a US Naval Base in North Africa. The package approach facilitated transoceanic shipping and private installation. Designed to handle medium flows of wastewater, this lift station includes duplex pumps, valves, a drop bowl, and a mushroom cap vent pipe as the key wet well components. To meet site requirements in the country of Djibouti, the UL listed control panel, pumps, and level-sensing controls were configured to operate with a European type of power supply.

Public Animal Shelter|Berkeley, CA|75 GPM - 25' TDH

jweddell50gpm - 100gpm, Hospitals, Pacific, Wastewater

A newly constructed public animal shelter required this package lift station to meet low sewage flows with additional animal waste. The difficulties associated with pumping animal waste required submersible solids-handling pumps in a duplex configuration. Variable frequency drives were included for electric phase conversion in order to utilize the appropriate pumps with the available power. A UL listed control panel includes float controls for liquid level-sensing and an autodialer with a basic alarm for emergency notifications.
