About the company
Tetra TECH Inc., through its Commercial/International Services Group Division, is a for-profit corporate entity headquartered in Huntsville, Alabama, operating as a division of the larger Tetra Tech, Inc., a global consulting and engineering firm based in Pasadena, California. The organization specializes in water and wastewater technical support services, infrastructure development, and engineering design for federal agencies, with demonstrated expertise in environmental remediation, water quality management, and complex infrastructure projects. As a large, established prime contractor, Tetra TECH has secured a significant presence within the federal contracting landscape, particularly with the U.S. Army Corps of Engineers and Department of Defense installations.
Tetra TECH's federal contract portfolio demonstrates a focused specialization in water infrastructure and wastewater management projects at military installations. Recent delivery orders include a $519,780.48 firm fixed-price contract awarded in September 2025 for evaluation and repair of the wastewater treatment plant at Yakima Training Center in Union Gap, Washington, with completion scheduled for September 2026; a $253,916.02 contract awarded in June 2024 for a water resiliency study at Anniston Army Depot in Alabama, completing September 2026; and a $532,045.45 contract awarded in December 2023 for construction of an industrial water supply system for Steam Plant A at Arnold Air Force Base in Tullahoma, Tennessee, originally scheduled for completion by August 2025. All identified contracts were awarded by the U.S. Army Corps of Engineers, Engineering District Mobile, with no small business set-aside designations applied, reflecting Tetra TECH's competitive standing as a large prime contractor. These delivery orders represent task orders issued under an existing Indefinite Delivery Contract vehicle, demonstrating the Corps' confidence in the contractor's capabilities for ongoing water and wastewater technical support.
Tetra TECH holds a $25 million Indefinite Delivery Contract with the U.S. Army Corps of Engineers, Engineering District Mobile, awarded on August 1, 2022, with a performance period extending through July 31, 2027. This multiple-award IDC was established to provide comprehensive water and wastewater technical support services supporting the Corps' Water and Wastewater Technical Center of Expertise, encompassing 19 engineering and scientific disciplines to manage multiple task orders related to both civil works and military construction water and wastewater programs. The contract solicitation originally sought small business providers for architect-engineer services; however, Tetra TECH, as a large business prime contractor, was competitively awarded a position on this vehicle. To date, the company has executed at least four delivery orders under this IDC, including the three substantive project-based orders noted above plus a guaranteed minimum services order valued at $1,000 awarded in August 2022. The IDV structure allows the Corps to efficiently procure specialized water infrastructure services across multiple military installations and civil works projects without requiring separate competitive procurements for each task.
