Sewage Digester System Maintenance

The Department of the Air Force Air Mobility Command is soliciting for Sewage Digester System Microbe Maintenance services at Little Rock Air Force Base (LRAFB). The contractor must provide qualified personnel, transportation, tools, equipment, materials, and services to maintain sewage microbe systems across seven facilities, including lift stations and non-lift stations with specialized bacterial consortium and equipment such as CHEMSEARCH Bio Amp programs, Pit Boss bacterial agents, and Eco Storm systems. Key requirements include a mandatory site visit, wastewater treatment licensure, compliance with all federal, state, and local regulations, monthly HAZMAT reporting, and achievement of 98% equipment operational time with treatment completions as scheduled. The government will evaluate proposals through a three-stage process: ranking by price, conducting technical evaluation on the lowest-priced offers to determine acceptability against solicitation specifications, and making an award once at least three acceptable offers are identified. The solicitation was posted on October 27, 2025, with a proposal due date of November 4, 2025, and Amendment 01 was issued on October 30, 2025, to include an unrestricted pricing schedule and supplemental clause updates.

This solicitation contains no small business set-aside designation and represents an unrestricted procurement open to all eligible contractors. The contract is structured with a base period and four option periods, each lasting 12 months, with specific line items addressing maintenance at individual lift stations and non-lift stations, though the amended pricing schedule currently shows $0.00 values pending contractor submission.
