This wastewater lift station was designed to meet the standards of the Lakehurst Naval Air Station while remaining cost effective. A duplex pump configuration utilized submersible 7.5 HP Weil Slicer Pumps to handle suspended solids in the sewage. A UL listed control panel was designed and manufactured in a NEMA 4 enclosure for outdoor operation. Nolta floats were used for the in-well liquid level sensing. The below-grade structural components were designed and supplied precast concrete vaults painted with a marine epoxy exterior coating to prevent moisture incursion.

This was a true lift station replacement by installing a new package lift station “in the hole” of the removed wet well. Submersible pumps in a duplex configuration were included to meet the low sewage flows from the federal training facility. The system valves were installed in the discharge piping inside the wet well to reduce cost and simplify the system. An outdoor alternator panel handles the controls for this package lift station. It was designed with floats for liquid level sensing and a basic alarm.

This replacement wastewater lift station was designed to meet the medium sewage flow requirements of this federal training facility. Submersible solids-handling pumps in a duplex configuration pumps the effluent through in-well valves and out a three-inch force main. An outdoor alternator panel handles the controls for this package lift station. It was designed with floats for liquid level sensing and a basic alarm. The wet well is accessible with a traffic-rated hatch.

USACE Prime Power|St. Roberts, MO|300 GPM - 143' TDH

These package lift stations were designed to meet the high head pumping requirements for this training facility of the US Army Corps of Engineers. For one station with over 7,000 ft. of 8” force main, 35 hp duplex submersible centrifugal pumps were supplied to achieve the 300 gpm flow rate . The second lift station used smaller, 4 hp duplex grinder pumps to meet its pumping requirements. Outdoor UL listed control panels utilize float controls for level-sensing and soft starters to provide advanced pump diagnostics and to reduce inrush currents. Autodialers were specified for communications.

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

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.
