On September 30, 2025, 374Water Inc. announced that the delivery of its AirSCWO 6 system to the Orange County Sanitation District (OC San) has been postponed. The company cited mutually agreed‑upon technology and infrastructure upgrades that progressed slower than expected, as well as supply‑chain delays for specific components, as the primary reasons for the delay.
The postponement also stems from delays in receiving the final permits required to operate the AirSCWO system in California. 374Water and OC San are awaiting the completion of the factory acceptance test (FAT) and the installation of new components from the vendor before shipping can proceed. The company emphasized that these upgrades are intended to enhance system performance and reliability.
According to the release, 374Water expects to ship the AirSCWO 6 system in the fourth quarter of 2025 or early 2026, contingent on the timely receipt of permits and completion of the FAT. The company remains committed to launching the system at OC San and is coordinating closely with the South Coast Air Quality Management District and other regulatory bodies to expedite the permitting process.
The delay will postpone the start of revenue generation from the OC San deployment, potentially affecting the company’s short‑term financial outlook. However, 374Water maintains that the upgraded system will provide long‑term operational benefits and is confident that the project will resume as soon as regulatory and supply‑chain constraints are resolved.
