Evoqua Water Technologies LLC

Evoqua Water Technologies LLC, operating as Siemens Water Technologies Corp, is a for-profit water treatment equipment and services vendor serving federal agencies as a prime contractor (96% of awards) across water purification, dialysis systems, reverse osmosis maintenance, deionization, and industrial water treatment. The Pittsburgh-based vendor competes full-and-open; it holds no SBA set-aside certifications and has not pursued set-aside categories across its recent prime footprint.

Evoqua's federal work centers on reverse osmosis and dialysis water systems, deionized water equipment rental and maintenance, water quality testing, and preventative maintenance for specialized water treatment infrastructure at healthcare, military, and research facilities. Representative recent prime work includes a $2.2 million firm-fixed-price definitive contract with Veterans Integrated Service Network 12 (VA) for dialysis and reverse osmosis testing and maintenance through February 2030; a $809.4 million definitive contract with VISN 7 for water purification services through December 2029; a $763.5 million firm-fixed-price purchase order with VISN 4 for deionized water system preventative maintenance, repair, and equipment rental at the Philadelphia VA Medical Center through February 2030; and a $6.14 million indefinite delivery contract with Naval Sea Systems Command for deionized water trailer rental and regeneration services to support ship repair at Washington state naval facilities through November 2028. Many contracts are sole-source awards recognizing Evoqua's status as original equipment manufacturer for its installed systems.

Customer concentration is moderate and bifurcated by order count versus dollar value. Across the top five customers by award volume, Naval Facilities Engineering Command (84 awards, $5.5 million), Naval Sea Systems Command (32 awards, $13.3 million), VISN 9 (29 awards, $4.8 million), VISN 4 (26 awards, $5.1 million), and the Coast Guard (25 awards, $801 thousand) account for 29% of all awards. When ranked by potential value, NAVSEA's $13.3 million across 32 awards rises to the top, followed by VISN 12 ($5.8 million, 16 awards), NAVFAC ($5.5 million, 84 awards), VISN 4 ($5.1 million, 26 awards), and VISN 9 ($4.8 million, 29 awards), which together represent 36% of combined potential value. The divergence signals that NAVFAC places many smaller individual task orders while NAVSEA anchors fewer, larger agreements for water trailer support.

Parent vehicle activity is concentrated on five IDIQs and BPAs. An Indefinite Delivery Contract 36C10G20D0038 hosts 36 task orders valued at $9.7 million combined; BPA N6883621A0003 carries 18 task orders ($2.2 million); BPA 36C24921A0005 holds 6 task orders ($792 thousand); IDC N4008521D0068 shows 5 task orders ($2.3 million); and IDC N4215821D0001 carries 5 task orders ($2.9 million). These vehicles enable rapid procurement across multiple VA VISNs and Navy installations without full competition for individual orders.

Activity has been volatile. Award volume peaked at 76 in 2023, fell to 59 in 2024, recovered to 76 in 2025, and dropped to 31 in 2026 year-to-date (through mid-July). Sixty-six awards with ultimate completion in the next twenty-four months carry a combined potential value of $14.8 million and represent near-term recompete exposure.

Service Contract Inventory reporting (SCI-reportable federal service contracts above the $150,000 threshold) shows $231 thousand in invoiced prime contract revenue in FY2024, supporting 0.2 FTEs with zero subcontractor labor engagement—all work self-performed. Government-paid median hourly rates on SCI contracts run $452.43/hr, with rates spanning $418.86/hr at the 10th percentile to $486.01/hr at the 90th percentile. SCI is a narrow window into Evoqua's federal revenue; the vendor's primary federal business centers on equipment procurement, product sales, and maintenance task orders under $150,000 or GSA/Navy IDVs, which SCI does not capture. The $231 thousand SCI-reportable amount is not representative of total federal services delivery.

Evoqua operates with a parent company structure; the source names Evoqua Water Technologies, LLC as the parent. The vendor holds subsidiary brand identities, including Siemens Water Technologies Corp and former trade names Usfilter Corp, which appear in older awards. Subcontractor engagement is minimal across the prime portfolio; 28 awards (4%) are sub-awards under primes including Huntington Ingalls Incorporated (DDG 51 class ship construction, LPD 30 programs), Triad National Security (Los Alamos National Laboratory management and operations), Massachusetts Institute of Technology Lincoln Laboratory, and Central Plateau Cleanup Company (Hanford cleanup). These sub-roles focus on ion exchange vessels, water treatment equipment, laboratory test equipment, and equipment disposal supporting defense and national laboratory programs.

Top NAICS codes emphasize water supply systems (141 awards), chemical product manufacturing (77 awards), and machinery repair and maintenance (73 awards). Top PSC codes reflect the portfolio: water purification equipment maintenance/repair (132 awards), medical and dental equipment maintenance (83 awards), chemicals (79 awards), and water purification equipment (76 awards). This distribution confirms Evoqua's positioning as a specialized vendor for government water infrastructure, healthcare facility dialysis support, and laboratory equipment maintenance across civilian, defense, and research agencies.
