The 309th Aircraft Maintenance Group at Hill Air Force Base, Utah, seeks contractors for a Blanket Purchase Agreement to provide septic pumping and lavatory cleaning services for C-130 airframes in preparation for maintenance and transit. The contractor must supply all labor, tools, equipment, PPE, and the proper C-130 hose and attachment fittings, with services including draining, flushing, cleaning, and winterizing reservoirs. Performance requires response within 24 hours for standard call-outs and 2 hours for emergency call-outs at Hill AFB. The BPA has a five-year ordering period and requires CMMC Level 1 compliance. Historically, approximately 20 lavatory pumping services per year have been needed.
