Scope of Work
The UPRR Marne IMF Wastewater Lift Station Project involved constructing a new industrial wastewater conveyance system, including excavation, trenching, backfilling, and dewatering to prepare the Union Pacific Railroad site for major underground improvements. Crews installed new HDPE and ductile-iron force mains, gravity sewer piping, manholes, precast utility structures, and all associated appurtenances to form a complete wastewater collection and conveyance network. The work included building a new duplex submersible wastewater lift station with pumps, controls, valves, concrete foundations, electrical service equipment, and SCADA integration to support automated operation and monitoring. The project required extensive site civil work, including subgrade preparation, aggregate base installation, asphalt paving, fencing modifications, and the protection of existing utilities during construction. Electrical scope included new conduit routing, pull boxes, grounding, wiring, MCC integration, and coordination with railroad requirements for power, signal, and communication systems. Upon completion, the contractor delivered a fully operational wastewater lift station and collection system designed to reliably handle industrial flows within the UPRR Marne facility.
Community Benefit
The completion of the UPRR Marne IMF Wastewater Lift Station Project improved wastewater management and environmental protection at a critical Union Pacific Railroad facility, helping ensure that industrial wastewater was safely collected and treated in accordance with state and federal standards. By upgrading the site’s wastewater conveyance infrastructure, the project reduced the risk of leaks, overflows, and groundwater contamination—issues that the EPA identifies as major concerns for aging industrial wastewater systems. The new lift station and piping network increased system reliability, supporting uninterrupted railroad operations that are essential to regional commerce and supply-chain efficiency. These improvements supported local environmental quality by preventing untreated industrial effluent from entering nearby soil or stormwater pathways, consistent with California’s Water Board requirements for industrial facilities. The upgraded infrastructure also reduced future maintenance needs, limiting disruptions to both rail operations and surrounding neighborhoods. Overall, the project strengthened the region’s environmental stewardship and supported safer, more sustainable industrial operations at one of Southern California’s key freight corridors.
