Evoqua Water Technologies LLC

Evoqua Water Technologies LLC, doing business as Siemens Water Technologies Corp, supplies water treatment and marine corrosion-prevention equipment to the Department of the Navy and Department of Veterans Affairs as a prime contractor (72% of recent awards) and as a subcontractor to naval shipbuilders. The vendor is a child entity of Xylem Inc., a for-profit manufacturer headquartered in Colorado Springs, Colorado, and competes on a full-and-open basis with no SBA set-aside designations across its federal footprint.

Evoqua's federal customer base is heavily concentrated in naval operations and maintenance. The top five customers account for 75% of recent award count, dominated by the Department of the Navy Naval Sea Systems Command (27 awards, $630 thousand combined potential value), the Department of the Navy Military Sealift Command (16 awards, $570 thousand combined potential value), the Department of the Navy Naval Supply Systems Command (3 awards, $8.4 million combined potential value), the Department of the Navy Secretary of the Navy Office of Naval Research (4 awards, $83 thousand combined potential value), and the Department of State Bureau of International Narcotics Law Enforcement (2 awards, $63 thousand combined potential value). The potential-value ranking diverges sharply from award count: Naval Supply Systems Command anchors 83% of combined potential dollars despite representing only 4% of award count, driven by two large definitive contracts for power supply manufacturing and modular units ($4.7 million and $3.7 million, respectively, awarded September 2021). The remainder of Evoqua's Navy work splits between high-volume, low-value purchase orders for component parts and maintenance services.

Evoqua's concrete capability portfolio centers on impressed current cathodic protection (ICCP) systems, chlorination equipment (ChloroPac hypochlorination systems for shipboard potable water generation), power supply units, flow meters, and water purification components. Representative prime work includes a $263.6 thousand Naval Sea Systems Command purchase order for two V-Cone Flow Meters with Smar Transmitters (September 2026), a $104.2 thousand Military Sealift Command order for ChloroPac cell assemblies and power supply controllers (June 2025), a $78.2 thousand Department of Veterans Affairs purchase order for a water filtration system to clean medical supplies at the Robley Rex VA Medical Center (August 2021, designated as a Coronavirus COVID-19 National Interest Action), and multiple sub-thousand purchase orders from Naval Sea Systems Command for fasteners, ferrules, and other discrete components supporting fleet maintenance.

In its subcontractor role, Evoqua delivers ICCP system design, fabrication, and inspection-and-repair services to major naval shipbuilders. Named primes include Marinette Marine Corporation (15 sub awards since July 2021 for ICCP systems and water technology on the FFG(X) Guided Missile Frigate detail design and construction program), Vigor Marine LLC (7 sub awards since January 2025 for ICCP system maintenance and cathodic protection on destroyer and sealift vessel depot modernization and regular overhaul availabilities), Huntington Ingalls Inc. (2 sub awards for CVN-75 and CVN-80 aircraft carrier engineering efforts, including power supply units and chlorinator converters), and BAE Systems Jacksonville Ship Repair LLC and BAE Systems Maritime Solutions Norfolk Inc. (2 sub awards for destroyer and amphibious transport dock ship repair direct material and fitting-out availability work).

Activity has grown year over year, from 7 awards in 2022 to 17 in 2024, with 15 awards in 2025 and 3 in early 2026. The vendor's combined potential value across all 69 awards (prime and sub) is $10.1 million, but combined dollars obligated (approximately invoiced or obligated value across the full contract histories) stands at $45.3 million — a ratio that reflects the vendor's earlier participation in the two large Naval Supply Systems Command definitive contracts that completed or are completing in 2023. The top category concentration by NAICS is Ship Building and Repairing (24 awards), followed by Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables (7 awards) and Water Supply and Irrigation Systems (5 awards). By PSC, the vendor's primary codes are Miscellaneous Ship And Marine Equipment and Water Purification Equipment (7 awards each).
