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.

Commercial Development|The Dalles, OR|50 GPM - 14.4' TDH

A new commercial development where a Goodwill retail store was being built needed this robust wastewater lift station. The hatch and below-grade structural components of this lift station have an H-20 rating for occasional traffic so that the system could be located in the parking lot of the development. This also included a below-grade, explosion proof electrical junction box. Goulds vortex pumps in a duplex configuration were chosen to handle unknown solids from future tenants of the development. Electrical controls were provided through a standard UL listed panel.

Ski Resort Retrofit|Stevens Pass, WA|65 GPM - 35' TDH

Romtec Utilities designed and supplied this wastewater lift station retrofit to meet the medium sewage flows at the Steven’s Pass Ski Resort. A major part of the retrofit supply package were two Vaughan submersible chopper pumps for wastewater. The electrical controls were the next significant portion of the retrofit. The PLC controller included a touchscreen HMI with autodialer telemetry and SCADA options to communicate with the resort treatment plant. This communication provides advance notification for the treatment plant as the lift station is nearly inaccessible during winter months.
