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.

Lake Union Park in Seattle Washington

Seattle Parks and Recreation|Seattle, WA|145 GPM - 20.8' TDH

jweddell100gpm - 300gpm, Municipal Collection, Pacific, Wastewater

A renovation of South Lake Union Park required a package lift station configured to meet the medium sewage flow requirements for a municipal and commercial wastewater system. Submersible solids handling pumps in a duplex configuration are protected from turbulence and cascading influent by a drop bowl. A separate below-grade valve vault holds the valves, gauges, indicators, and actuators. A UL listed control panel utilizes float controls for primary and backup liquid level-sensing and is housed in a nearby control building.

jweddell100gpm - 300gpm, Municipal Collection, Pacific, Sewer System Expansion, Wastewater

This municipal lift station in the Napa Valley was designed to handle medium sewage flows and medium head conditions. Flygt sewer pumps were supplied in a duplex configuration to integrate with the Tops Basin and discharge elbows. The complete structural components of this lift station were designed to finish two feet above-grade to be above the flood plain for the area. A proprietary control device and pressure transducer provide the system electrical controls.

jweddell300gpm - 500gpm, Municipal Collection, Municipal Lift Station Replacement, Pacific, Replacements & Retrofits, Wastewater

This municipal lift station replacement was configured to handle medium flows of sewage from a large area of Wenatchee, Washington. This deep wet well was constructed from precast concrete and includes Tnemec interior coating. Vaughan Chopper Pumps in a duplex configuration were selected to macerate solids and alternate pumping cycles. A PLC with a touchscreen interface provides an easy and flexible control panel. The primary level-sensing device is a pressure transducer with floats backup level-sensing. This control panel also uses soft starters to reduce current inrush to the 30 hp pumps.
