About the company
Waste Connections Of South Dakota, Inc., doing business as Kieffer Sanitation, delivers solid waste collection, disposal, and recycling services to federal agencies across the Northern Great Plains as a prime contractor operating under full-and-open competition with no set-aside posture. The vendor is a for-profit subsidiary of Waste Connections Of Florida, Inc., headquartered in Rapid City, South Dakota, and has maintained continuous federal contracting capability since May 2006.
The vendor's customer base concentrates in National Park Service operations and Veterans Affairs medical facilities. The National Park Service Midwest Region accounts for 10 awards worth $1 million in combined potential value, anchored by a newly awarded single-award indefinite-delivery contract for solid waste and recycling services at Mount Rushmore National Memorial (ceiling $165,302, award date May 27, 2026, through September 30, 2031) and a $317,082.84 five-year purchase order for waste collection at Badlands National Park (April 1, 2025, through March 31, 2030). The Department of Veterans Affairs Veterans Integrated Service Network 23 represents the second-largest customer by potential value with a $713,632.60 total small-business-set-aside purchase order for solid waste collection and disposal at Fort Meade and Hot Springs medical centers (February 1, 2022, through January 31, 2027). The Department of the Air Force, split between Air Combat Command (6 awards, $351 thousand) and Defense Finance and Accounting Service (1 award, $768 thousand), comprises the remaining concentration. Of 40 prime awards spanning 11 distinct customer agencies, the top five customer listings account for 96% of combined potential value.
The vendor operates primarily under NAICS 562212 (Solid Waste Collection) and PSC S205 (Housekeeping—Trash/Garbage Collection), with 21 awards in solid waste collection, 6 in miscellaneous waste management services, and 3 each in other waste collection, landfill operations, and septic tank services. Delivery-order and purchase-order activity under specific parent vehicles includes 4 task orders ($51 thousand combined potential value) under U.S. Air Force Blanket Purchase Agreement FA469013A0007 and 3 task orders ($61 thousand combined potential value) under an Indefinite Delivery Contract 140P6321D0004.
Recent activity has remained modest and episodic—one award in 2022, one in 2023, one in 2024, three in 2025, and two year-to-date in 2026—with combined potential value across all 40 awards totaling $3 million (74% obligated). Three awards worth $761 thousand in combined potential value reach ultimate completion within the next twenty-four months, presenting recompete opportunity for competitors and contract-retention risk for the vendor. The vendor operates exclusively as a prime; no subcontract activity appears in the source.
