Upgrade/Replace Lift Station and Sump Pit Pumping Systems

USDA’s Animal and Plant Health Inspection Service has a requirement to upgrade a lift station at the National Center for Applied Plant Protection facility in Laurel, MD. Due to the multiple maintenance issues, antiquated equipment, and operational criticality for the facility, the current lift station pump system and downstream sump pump systems are obsolete and need replacing. The current system uses six Zoeller Model G294-E pumps (two pumps in three locations) installed in lead/lag configurations for redundancy.

Several key components on the system are either deteriorating or inoperable, including deteriorating guide rails and supports needed for repair and/or replacement of the pumps. The effluent discharge piping has been reworked several times due to clogging with silt and other materials and is undersized for its application, resulting in numerous clogs requiring labor-intensive maintenance. Additionally, the discharge piping is not supported properly and routed improperly to facilitate proper function.

The piping also blocks access to the adjacent pump control panels, creating an additional hazard for personnel maintaining the system. The project includes installation of three new silt and solid handling pump systems within the lift station and downstream sump pump systems, including all required guiderails, supports, controls, valves, and piping modifications. The pumping systems must be fully automated, high efficiency, and equipped with redundant features.

These features will ensure the system is effective and lead to consistent results without making the process cumbersome or inconvenient. Contractor will connect the new pump systems to the existing site/building infrastructure and computer system. Likewise, the pumps must be a “stock unit” for ease of acquiring service and repair. The NAICS code for this project is 237110—Water and Sewer Line and Related Structures Construction, with a small business size standard of $45 million.

The estimated magnitude of the project is between $100,000 and $250,000. The project will be set aside for small business concerns only. The solicitation will be posted on or about July 14, 2025. It is the responsibility of interested parties to monitor this site for the solicitation and amendments, if any.
