I can confirm that UFM 3-240-03 exists and is current as of 17 February 2026. It is the Unified Facilities Manual for Operation and Maintenance: Wastewater Treatment [UFM 3-240-03].
Key characteristics:
UFM 3-240-03 is a non-mandatory, informational guidance document that supports Unified Facilities Criteria (UFC) with focus on facilities operations and maintenance. It provides recommended procedures, checklists, and explanatory material but does not create new requirements or modify UFC content [UFM 3-240-03 Foreword]. The manual includes operational procedures and maintenance practices for wastewater treatment systems, such as winter problem mitigation strategies for biological treatment systems [UFM 3-240-03, Table A-4 discussion].
If you have a specific question about wastewater treatment operations, maintenance procedures, or content covered in UFM 3-240-03, please ask and I can search the available passages for the answer.
