Shamrock Septic Services Inc.

Shamrock Septic Services Inc., doing business as Shamrock Septic Service Inc., is a woman-owned small business based in Mound House, Nevada, that operates exclusively as a prime contractor supplying portable sanitation equipment, water trucks, and incident support services to federal land management agencies across the western United States. The vendor competes under Total Small Business set-asides for its largest contract vehicles and on full-and-open delivery orders from regional Forest Service and Bureau of Land Management offices.

Shamrock's capability portfolio centers on portable toilet rental, handwashing station setup, potable and gray water truck deployment, and septic system maintenance to support wildland firefighting and emergency response operations. Representative work includes a $7.5 million Incident Blanket Purchase Agreement from the National Interagency Fire Center (awarded July 2022, running through June 2027) that anchors supply of portable toilets and handwashing stations nationwide for Forest Service, Bureau of Land Management, National Park Service, Bureau of Indian Affairs, and U.S. Fish and Wildlife Service incident response. Shamrock also holds a $500,000 Total Small Business multiple-award IDC from the National Interagency Fire Center (awarded February 2026, through May 2029) for potable and gray water trucks and trailer-mounted handwashing stations supporting Forest Service Regions 1, 2, and 4. Task-order activity under these vehicles includes a $44,168 delivery order from USDA Forest Service Region 4 (Intermountain Region) in May 2025 for septic system maintenance and water truck services in Sparks, Nevada, and a $36,632.50 delivery order from Forest Service Region 5 (Pacific Southwest Region) in July 2023 for septic services in Bishop, California.

Customer concentration is dominated by federal land management agencies. The top five funding customers account for 77% of recent award count: USDA Forest Service Region 4 (Intermountain Region) leads with 24 awards valued at $685 thousand combined potential value, followed by the Department of the Interior Bureau of Land Management Nevada Region with 22 awards at $1.3 million combined potential value. By dollar magnitude, however, the National Interagency Fire Center anchors the portfolio with 9 awards carrying $8.9 million combined potential value — representing 76% of Shamrock's total potential value across 88 awards totaling $11.7 million. The vendor serves ten distinct federal agencies, but activity concentrates on Forest Service and BLM regional offices in Nevada, California, Arizona, and New Mexico.

Recent activity shows volatility. Awards per year tracked seven in 2022, six in 2023, declining to two in 2024, then recovering to eight in 2025 and ten in 2026 (through late August). The vendor holds three named indefinite-delivery vehicles: the $7.5 million NIFC Incident Blanket Purchase Agreement (15 task orders recorded), a $500,000 NIFC multiple-award IDC (February 2026 award), and a $250,000 NIFC multiple-award IDC (May 2024 award). Work is categorized primarily under NAICS 562991 (Septic Tank and Related Services) on 37 awards and NAICS 561730 (Support Activities for Forestry) on 40 awards, with PSC L043 (Lease or Rental of Equipment—Toiletries) dominating at 26 awards and PSC 4310 (Natural Resources/Conservation—Forest-Range Fire Suppression/Presuppression) at 27 awards. The vendor has no subcontract footprint and operates as a pure prime across all 88 awards. Combined dollars obligated total $1.6 million against $11.7 million combined potential value, indicating a 14% obligation rate typical of indefinite-delivery vehicles in early execution phases.
