The Marathon Petroleum Refinery in Robinson, IL needed this new industrial process water pump station to handle its medium flows of highly acidic water combined with standard wastewater. A precast concrete sump included an interior Tnemec coating to withstand the water chemistry from a refinery testing lab. 11 hp Goulds grinder pumps were designed in a duplex configuration and included a factory epoxy coating to withstand the water chemistry. The pump station piping was designed with stainless steel components, and corrosion resistant floats were included as the liquid level sensing devices.

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.

This municipal water district replaced an existing lift station with this packaged lift station designed for the high sewage flow requirements. 15 hp submersible sewage pumps discharges to a below grade valve assembly, which includes valves, actuators, indicators, and access ports. The outdoor control panel utilizes a pressure transducer for primary liquid level sensing and float controls for backup. The panel also includes soft starters to reduce the inrush current, which can sap the onsite generator during pump starts.

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.
