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 supplies portable sanitation equipment, water trucks, and incident support services to federal land management agencies as a prime contractor under small business set-asides and full-and-open competition. The vendor operates exclusively as a prime (100% of awards) across wildland firefighting, forest management, and emergency response operations, with no subcontract footprint.

Shamrock's capability portfolio centers on portable toilet rental, handwashing station setup, potable and gray water truck deployment, septic system maintenance, and weed-washing equipment provision to support temporary sanitation and incident logistics for the U.S. Forest Service, Bureau of Land Management, and National Interagency Fire Center across the western United States. Representative work includes a $7.5 million Indefinite Delivery Contract with the National Interagency Fire Center (awarded July 2022, running through June 2027) for portable toilets, wheelchair-accessible portable toilets, and handwashing stations supporting fire suppression and all-hazard incidents nationwide; a $250,000 Total Small Business IDIQ awarded February 2026 by the National Interagency Fire Center for potable and gray water trucks and trailer-mounted handwashing stations serving Forest Service Regions 1, 2, and 4 through May 2029; and a $44,168 delivery order from USDA Forest Service Region 4 (Intermountain Region) in May 2025 for temporary sanitation and incident support services in Sparks, Nevada.

Customer concentration is heavily weighted to the National Interagency Fire Center, which accounts for 9 awards totaling $8.7 million combined potential value (77% of the portfolio's total $11.3 million value). The Department of the Interior Bureau of Land Management Nevada Region ranks second by award count (22 awards, $1.3 million) but trails significantly in dollar terms, reflecting the vendor's reliance on one large ceiling contract anchoring the portfolio. USDA Forest Service Region 4 (Intermountain Region) places 21 awards valued at $636 thousand. The top five customers by award count account for 79% of all awards; by potential value, the top five represent 98% of dollars, underscoring significant concentration in the NIFC vehicle.

Shamrock holds three active parent IDIQs under small business set-asides: the $7.5 million NIFC Incident Blanket Purchase Agreement (awarded July 2022), the $250,000 NIFC Potable and Gray Water Truck IDIQ (May 2024), and a second $250,000 NIFC Potable and Gray Water Truck vehicle (February 2026). Task order activity under these vehicles has generated 11 orders against the primary $7.5 million NIFC contract, 5 orders under one $250,000 vehicle, and 3 orders under the second $250,000 vehicle. The vendor also executes delivery orders against regional Forest Service and Bureau of Land Management contract vehicles, with recent smaller vehicles such as Indefinite Delivery Contract 1202RZ22T0080 (11 task orders, $134 thousand combined value) and Blanket Purchase Agreement 140L1319A0006 (5 task orders, $96 thousand combined value).

Work is performed across Nevada, California, Arizona, and New Mexico, with primary operational bases in Sparks and Mound House, Nevada, and Boise, Idaho. Award activity declined from 7 awards in 2022 to 2 in 2024 before rising to 8 in 2025 and 2 in 2026 year-to-date (as of mid-June 2026). Shamrock operates under NAICS 562991 (Septic Tank and Related Services, with a $9.0 million small business size standard) and PSC L043 (Lease or Rental of Equipment—Toiletries), competing predominantly under Total Small Business set-asides on its three core IDIQ vehicles, though individual delivery orders frequently carry no set-aside designation when drawn against those contracts.
