Walt Bannon Drilling, Inc.

Walt Bannon Drilling, Inc., headquartered in Oakhurst, California, operates as a prime contractor delivering well drilling, water system construction, and sanitation services to federal agencies, with a recent recertification as a Total Small Business under NAICS 221310 (Water Supply and Irrigation Systems) and 2211 (Water, Sewage and Other Systems). The vendor competes full-and-open, holding no SBA set-aside designations across its portfolio; one recent award carries a Total Small Business set-aside, but the vast majority of its eighty-three prime contracts are unset.

Walt Bannon's customer footprint concentrates heavily on the Department of Health and Human Services Indian Health Service, which accounts for 31 awards and $4.8 million of the vendor's combined potential value across 78% of recent prime awards. The Department of the Interior National Park Service Pacific West Region follows distantly, with three awards worth $166 thousand combined, primarily for deep-well rehabilitation and repair work at Yosemite Valley. The Department of Health and Human Services Public Health Service represents a secondary volume (26 awards), though the source does not provide a separate potential-value figure for that agency. The Occupational Safety and Health Review Commission and other agencies round out the customer set. Within the top-value ranking, IHS dominates at $4.8 million, with the NPS Pacific West Region and PHS following; the two rankings are nearly congruent, signaling stable customer concentration without tension between order volume and deal size.

Walt Bannon operates on five named indefinite delivery contracts, with fifteen task orders flowing through Indefinite Delivery Contract 235990019 (no combined potential value stated in the source) and twelve task orders under Indefinite Delivery Contract 75H70318D00001 ($471 thousand combined potential value). Three additional IDCs (HHSI235201400002I, 235030002, and HHSI235200810000I) carry smaller task order counts. Scope concentration aligns with the NAICS and PSC profile: forty-two awards fall under Water and Sewer Line and Related Structures Construction, while the top project service codes span Construction of Waste Treatment and Storage Facilities (thirteen awards) and Construction of Water Supply Facilities (eleven awards). Recent representative work includes a $97.5 thousand Total Small Business purchase order from NPS Pacific West Region (April 2026) for rehabilitation of Well No. 2 at Yosemite Valley, involving turbine pump extraction at 187 feet, component inspection and refurbishment, spider bearing replacement, and compliance with AWWA C654-03 disinfection standards; a $51.8 thousand firm fixed-price purchase order (January 2024, NPS) for water well repair services in Yosemite National Park; and a $28.5 thousand purchase order from the Indian Health Service (May 2023) for well drilling services at the Josh Wallace Site in North Fork, California.

Activity has contracted significantly over the past five years—three awards in 2021, three in 2022, one in 2023, one in 2024, and one in 2026—indicating a decline in volume and frequency. Combined potential value sits at $5.6 million with $2.6 million obligated (45% execution rate). The vendor operates exclusively as a prime; no sub-award history appears in the source. The vendor's first federal award in the source data dates to 1988, signaling decades of operational tenure in federal water and sanitation infrastructure for tribal and park service programs.
