White Mountain Apache Tribe

White Mountain Apache Tribe, doing business as White Mountain Apache Tribe Utility Auth, is a federally recognized Indian tribe providing water, wastewater, and tribal employment rights office support to federal agencies as a prime contractor operating under tribal government structure, with no set-aside designations applied across its recent award footprint.

The White Mountain Apache Tribe is headquartered in Whiteriver, Arizona, and operates as a tribally owned entity under parent structure White Mountain Apache Tribe (a tribal government). The vendor functions as a prime contractor on 93% of its federal awards, with a small sub-award footprint in grant programs. Recent work centers on two concrete capability streams: water and wastewater utility services delivered to Indian Health Service facilities and Department of Interior Bureau of Indian Affairs locations, and Tribal Employment Rights Office (TERO) administrative support delivered to the Equal Employment Opportunity Commission. Representative contract work includes a $391 thousand definitive contract with the Indian Health Service for water and wastewater services to the Whiteriver Service Unit Hospital Campus (award date June 1, 2022; ultimate completion date July 31, 2027), a $138 thousand purchase order from the Department of the Interior Western Region for water and sewer services at Fort Apache Agency (award date September 24, 2024; completion date September 30, 2029), and recurring annual $33 thousand definitive contracts with the Equal Employment Opportunity Commission for FY 2026 and FY 2025 TERO support.

Customer concentration is diffuse across tribal-focused federal agencies. The Department of Health and Human Services Indian Health Service anchors potential value (2 awards, $594 thousand combined value), followed by the Department of the Interior Bureau of Indian Affairs Western Region (8 awards, $455 thousand), and the Equal Employment Opportunity Commission (11 awards, $275 thousand). Combined, these three agencies represent 96% of the vendor's combined potential value and 93% of awards. NAICS concentration reflects the utility services core: Human Rights Organizations (10 awards, tied to TERO work), Water Supply and Irrigation Systems (4 awards), and Sewage Treatment Facilities (4 awards) dominate the classification base.

Activity is sparse and episodic. Over the past five years, the vendor recorded one award in 2021, one in 2022, three in 2024, two in 2025, and one in 2026. Total federal awards across the source window number 27 (both contract and grant work), with combined potential value of $1.5 million and combined obligated dollars of $1.5 million, indicating full-spend or over-spend positions. One award (the Indian Health Service water and wastewater contract) carries $391 thousand in combined potential value and faces ultimate completion within the next twenty-four months, representing recompete exposure for that work stream. The vendor also holds two grant sub-awards from the Arizona Department of Education (July 1, 2025, and July 1, 2026), acting as a sub-recipient under education-infrastructure grant programming. Place of performance is Whiteriver, Arizona, for all water and wastewater work and for TERO support; all work is performed locally on tribal lands or at tribal federal service units.
