Marilyn Klasen

Marilyn Klasen, doing business as Klasen Septic Pumping, a woman-owned sole proprietorship based in Dillon, Montana, provides septic pumping, portable toilet servicing, handwashing stations, and waste removal services to federal land management agencies as a prime contractor under small business set-asides. The vendor operates exclusively in the prime role (100% of recent awards), with no subcontract footprint, and competes predominantly under Total Small Business set-asides across NAICS 562991 (Septic Tank and Related Services) and PSC Natural Resources/Conservation codes.

Klasen Septic Pumping's customer concentration heavily favors the Department of Agriculture Forest Service Fire and Aviation Management division at the National Interagency Fire Center, which accounts for only 6 awards but carries $8.8 million in combined potential value — a stark divergence from the award-count ranking. The Department of Agriculture Forest Service Region 1-Northern Region (Montana-Dakotas) dominates volume with 59 awards worth $1.8 million combined potential value, followed by the Department of the Interior Bureau of Land Management Montana-Dakotas with 15 awards worth $3.4 million. The vendor also works with the Bureau of Reclamation and U.S. Fish and Wildlife Service on smaller regional contracts. Collectively, the top five customer lines represent 77% of all recent awards and 99% of combined potential value.

Klasen Septic Pumping holds three active indefinite-delivery contracts anchoring its federal footprint. A June 2026 National Interagency Fire Center multiple-award IDIQ carries a $7.5 million ceiling through June 2027 for nationwide portable-toilet and handwashing-station supply and service supporting wildland fire suppression and all-hazard incidents across all 50 states. A February 2026 National Interagency Fire Center IDIQ holds $500 thousand for potable and gray water truck/handwashing stations (trailer-mounted) serving Forest Service East Zone Regions 1, 2, and 4 through May 2029. A May 2024 USDA Forest Service Virtual Incident Procurement IDIQ provides $250 thousand for water and sanitation services across Regions 1, 2, and 4. Below these vehicles, older Forest Service and Bureau of Land Management IDIQs continue to generate task orders at lower dollar values — the top parent vehicle (an aged Forest Service IDIQ) carries 15 task orders worth $160 thousand combined potential value. Representative delivery-order work includes a $48 thousand firm fixed-price septic-pumping order from USDA Forest Service Region 1 (August 2023), a $243.7 thousand purchase order for Madison River vault pumping and janitorial services under Total Small Business set-aside (July 2023, Option Year 3 running through April 2028), a $45.5 thousand Bureau of Reclamation total small business set-aside for vault and septic pumping at Clark Canyon and Barretts Recreation Areas (June 2023, completion May 2028), and a $19.7 thousand USDA Forest Service Region 1 delivery order for septic-pumping services under Total Small Business set-aside (August 2026).

Activity shows modest recent flow — three awards in 2022, four in 2023, one in 2024, four in 2025, and three through August 2026 — with only two awards reaching ultimate completion within the next twenty-four months (combined potential value $289 thousand), leaving the vendor's largest IDIQs secure through 2027–2029. The vendor has maintained a registered SAM.gov account since 2003, with prior contract values ranging from $4.1 thousand to $243.7 thousand, establishing a long-standing federal contracting presence in western land management and incident-response operations.
