The IBM Boulder Data Center needed to replace a wastewater lift station with a new system to handle medium flows of wastewater generated at the facility. A precast concrete sump includes a pedestrian rated hatch with a safety grate for reliable fall protection. Two, Ebara 5 hp pumps were included in the design for redundant pumping capabilities, and a prefabricated valve vault structure contains check valves and control valves. A UL listed control panel with phase monitoring was engineered in a NEMA 4X stainless steel enclosure for installation outdoors.
DJ Farms|Guadalupe, CA|135 GPM - 36.8' TDH
This City of Guadalupe, California needed a new wastewater lift station to accommodate a residential development for up to 800 homes.
Lakehurst Naval Air Station|Trenton, NJ|250 GPM - 24.77' TDH
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.
Bay Meadows | San Mateo, CA | 1218 GPM - 96' TDH
After the historic Bay Meadows racetrack closed down, a large residential development began that required this large wastewater lift station. A triplex configuration of 30 hp Flygt pumps handles the high flow rates of this system. A blower system was provided as part of the lift station odor control specified by the City. The lift station electrical controls comprised a PLC, float control level-sensors, and a backup generator. The panel includes an Arc Armor® enclosure that provides safe access to low-voltage controls and separate access for high-voltage circuits.
Federal Training Center|Bruswick, GA|40 GPM - 15' TDH
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.
