Reverse Osmosis Water Purification Unit (ROWPU)

The U.S. Marine Corps, through the Product Manager Engineer Systems under the Department of Defense, is conducting market research via a Request for Information (RFI) to identify commercial off-the-shelf (COTS) Reverse Osmosis Water Purification Units (ROWPU) capable of producing at least 1,200 gallons of potable water per hour from seawater and brackish sources. This RFI, issued under solicitation number M67854-26-I-5331 and posted on June 23, 2026, with a response deadline of July 23, 2026, is strictly for gathering industry capabilities and is not a solicitation for proposals or quotations. The government does not intend to award a contract or compensate respondents for information provided, and all submissions must be received by 10:00 a.m. local time in Quantico, Virginia, via email or DoD SAFE in a single, consolidated document not exceeding five pages, formatted in Microsoft Office or searchable PDF. The target system is intended to replace the legacy Tactical Water Purification System and must be significantly lighter, more reliable, and require less power, with operational thresholds of 1,000 gallons per hour and an objective of 1,500 gallons per hour, while consuming no more than 30 kilowatts (threshold) or preferably 15 kilowatts (objective). It must be transportable on a single 463L pallet and compatible with C-130, C-17, and CH-53 aircraft, transitioning from operational to transport mode within two hours as an objective and three hours as a threshold. Performance must be sustained across environmental conditions ranging from 25°F to 120°F, with the system capable of operating under MOPP-IV chemical, biological, radiological, and nuclear conditions and producing water compliant with TB MED 577, NAVMED P-5010-10, and AFMAN 48-138_IP standards. Respondents are required to provide business name, size classification including small business status, point of contact information, and confirmation of eligibility under SBA socioeconomic programs such as SDB, SDVOSB, HUBZone, or 8(a), but are not required to submit UEI or CAGE codes. The Marine Corps anticipates a future procurement of up to 145 units under a potential
