Hosan Sanitation Co., LTD.

Hosan Sanitation Co., LTD., a South Korean environmental remediation and waste management company based in Daegu, supplies portable latrine services, sludge removal, grey water disposal, and related facilities sanitation to the U.S. Army as a prime contractor exclusively, with 100 awards across multiple indefinite-delivery and blanket-purchase vehicles since 2017. The company competes entirely on a full and open basis with no set-aside designations across its federal contract portfolio.

Hosan Sanitation's customer base is concentrated within a single federal department. The Department of the Army accounts for 100% of awards across three organizational entities: the Army Installation Management Command Pacific Region leads with 63 awards worth $6.3 million in combined potential value, followed by the Department of the Army Pacific Command with 4 awards worth $2.9 million, the Department of the Army proper with 32 awards worth $781 thousand, and the United States Marine Corps with 1 award worth $14 thousand. The rank-order by dollar value mirrors the count ranking, indicating tight alignment between volume and value concentration. All work is performed at U.S. Army installations in South Korea under firm fixed-price arrangements.

Hosan Sanitation holds four active parent vehicles totaling more than $10 million in combined ceiling value. The largest vehicle is Blanket Purchase Agreement W91QVN18A0010, a $2.8 million multiple-award BPA established July 1, 2023, and running through July 4, 2028, for portable latrine manual removal, cleaning, and maintenance; manual car washing; grey water removal and disposal; sludge removal; and environmental remediation services across Army installations in Area IV of South Korea. Hosan has issued 54 task orders against this BPA totaling $1.3 million in potential value, with individual calls ranging from approximately $2,382 to $141,931. Three single-award indefinite-delivery contracts complete the vehicle portfolio: a $469.7 million ceiling contract awarded September 1, 2026 (most recent award in source), for accumulated sludge removal at USAG Daegu through August 31, 2031; a $218.2 thousand contract awarded December 21, 2023, for sand, soil, and sludge removal from sewage facilities in Daegu through December 31, 2026, with three delivery orders obligating $130.5 thousand; and two earlier IDCs supporting grey water and sludge work. The $2.8 million BPA anchors the portfolio and carries the most task-order volume.

Work is classified under NAICS 562910 (Septic Tank and Related Services) for 88 of 100 awards, with the remainder split among other nonhazardous waste treatment and disposal and waste collection codes. PSC coding emphasizes equipment lease or rental for toiletries (71 awards) and housekeeping operations (22 awards combined across trash, waste treatment, and sewage facility categories). Award activity declined from 14 in 2023 to 6 in 2026 year to date; 2 awards (combined potential value $136 thousand) face ultimate completion within the next twenty-four months and represent recompete exposure. The company has obligated $2.7 million of its $10 million combined ceiling, a 27% obligation rate reflecting ongoing task-order issuance against standing vehicles rather than exhaustion of vehicle capacity. Hosan Sanitation has maintained continuous prime-contractor engagement with the Army Pacific Region since October 2017 SAM registration and holds no subcontract positions in the source record.
