Chambers Drilling Company

Chambers Drilling Company, a for-profit Subchapter S corporation based in Kalispell, Montana, operates as a prime contractor delivering well drilling, well pump replacement, and water supply infrastructure services to federal agencies under total small business set-asides. The vendor holds 13 federal awards spanning three decades, all as prime (100%), with no subcontract footprint. Recent work centers on water resource installation and maintenance for the Department of Interior Fish and Wildlife Service, the Department of Energy Bonneville Power Administration, and the Department of Agriculture Forest Service.

Chambers Drilling's capability portfolio is tightly scoped to specialized drilling and water infrastructure work. Three named recent awards illustrate the scope: a $123,916 firm fixed-price purchase order from the Bonneville Power Administration (awarded February 2023) for installation of a resource well up to 60 feet deep in Libby, Montana, with steel casing, buried slab, trenching, and power distribution; a $28,125 purchase order from the Department of Interior Fish and Wildlife Service Region 6 (awarded August 2026) for well abandonment at the MT Creston National Fish Hatchery in Kalispell; and a $9,475 purchase order from the same FWS Region 6 (awarded December 2024) for well pump replacement at MT Creston. Award coding clusters around two PSC categories — Natural Resources/Conservation-Well Drilling/Exploratory (4 awards) and Maintenance/Repair/Rebuild of Equipment-Pumps and Compressors (1 award) — with NAICS alignment to Water and Sewer Line and Related Structures Construction (5 awards) and Water Supply and Irrigation Systems (4 awards).

Customer concentration is diffuse. The Bonneville Power Administration leads by potential value ($124 thousand), followed by the Forest Service R1-Northern Region ($54 thousand) and the FWS Region 6 ($38 thousand combined across two awards). Activity is episodic: one award in 2021, one in 2023, one in 2024, and one in 2026, reflecting the project-driven nature of federal drilling work. One award carrying $28 thousand in potential value reaches completion within the next twenty-four months. The vendor has no presence on standing IDIQs, GWACs, or BPAs; all awards are discrete purchase orders for discrete site work.
