Lost Creek Properties Inc.

Lost Creek Properties Inc., doing business as Ewbank GEO, is a small-business prime contractor specializing in water well drilling, septic system installation, drainfield construction, and related water infrastructure services for the Indian Health Service across Oklahoma. The vendor operates exclusively under total small business set-asides and has delivered 256 IHS awards worth $12.1 million in combined potential value since at least 2022, representing 100 percent of its federal footprint tracked in the source.

Ewbank GEO's work centers on concrete water infrastructure and sanitation systems serving American Indian and Alaska Native communities. Representative prime awards include a $2.5 million comprehensive single-award BPA (75H71125A00002, awarded May 2025, running through April 2030) covering water well drilling, septic system installation, drainfield construction, and aerobic systems across all Oklahoma Area Field Offices; multiple regional BPAs valued at $150,000 to $250,000 each covering the Lawton, Shawnee, Clinton, Pawnee, and Okmulgee field offices; and individual BPA task orders typically ranging from $9,000 to $32,000 for discrete water well drilling, well renovation, and septic installation projects. A representative task order example: a $171,415 BPA call (awarded August 2025, set-aside total small business) for water well installation across Shawnee, Okmulgee, Clinton, and Pawnee field offices under the parent Clinton BPA. The vendor operates as a prime on 100 percent of awards; no sub-award footprint is present in the source.

The Indian Health Service dominates customer concentration absolutely, funding 256 of 256 awards (100 percent, $12.1 million combined potential value). The Department of the Interior National Park Service accounts for 2 additional awards with no dollar detail in the source. Activity has been volatile—46 awards in 2022, declining to 20 in 2024, then recovering to 27 in 2025 and 2 awards in the first half of 2026. The combined potential value of awards reaching ultimate completion in the next twenty-four months is not separately stated in the recompete-cliff block, but the source indicates multiple BPAs expire through September 2025 (three agreements valued at $250,000 each) and April 2030 (the $2.5 million comprehensive BPA), suggesting moderate near-term recompete exposure on the regional agreements.

Ewbank GEO holds at least fifteen active single-award BPA parent vehicles with IHS. The top five by task-order count are BPA 75H71123A00062 (15 task orders, $259 thousand), BPA 75H71123A00038 (14 task orders, $236 thousand), BPA 75H71123A00028 (12 task orders, $220 thousand), BPA 75H71123A00041 (10 task orders, $161 thousand), and BPA 75H71123A00045 (10 task orders, $213 thousand)—all single-award, firm fixed-price IDIQs reserved for total small business set-asides, with completion dates ranging from May 2025 to April 2030. Work is performed at multiple IHS field office locations throughout Oklahoma (Cleveland, Clinton, Okmulgee, Shawnee, Pawnee, Lawton), with place of performance reflecting the geographic scope of each field office service area. The vendor's NAICS concentration is 256 awards under 237361 (Water and Sewer Line and Related Structures Construction); PSC concentration is 253 awards under Z100 (Construction of Water Supply Facilities), with 3 awards under Z200 (Construction of Sewage and Waste Facilities) and 2 under Z400 (Natural Resources/Conservation—Well Drilling/Exploratory).
