UFM 3-240-03 17 February 2026 UNIFIED FACILITIES MANUAL (UFM) APPROVED FOR PUBLIC RELEASE; DISTRIBUTION UNLIMITED OPERATION AND MAINTENANCE (O&M): WASTEWATER TREATMENT UFM 3-240-03 17 February 2026 FOREWORD Unified Facilities Manuals (UFM) provide non-mandatory, informational guidance in support of Unified Facilities Criteria (UFC) with a specific focus on facilities operations, and maintenance. Only UFC establish enforceable requirements. UFM are For Information Only (FIO) and exist to help users understand and apply UFC requirements. The purpose of UFM is to share operational procedures, maintenance practices, and practical examples that support effective implementation of UFC criteria during operations and maintenance activities. UFM may include recommended procedures, checklists, illus

Traveling bridge controls ice-up Build enclosure over controls. Icing of bus bar for bridges Install heat guns or warm air blower. Switches on monorakes freeze Shut off units in snow and ice to prevent freezing. Accumulation of snow on monorake rails stops wheels Shut down rake during snowstorms and remove snow. Automatic sampler freezes Build insulated boxes heated with a 100- watt light bulb. Waste activated sludge lines freeze Locate lines deeper. Install proper drainage. Source: SR 85-11.

aintenance activities. UFM may include recommended procedures, checklists, illustrations, or explanatory material, but they do not create new requirements, modify UFC content, or establish mandatory standards. UFM are developed by Discipline Working Groups (DWGs) and published by the Military Services under MIL-STD-3007. Because they are not criteria, they do not require Coordinating Panel (CP) or Engineering Senior Executive Panel (ESEP) approval. UFM content may be referenced or incorporated into operations, maintenance, or project documentation at the discretion of project delivery teams, but it is not binding unless explicitly included in contract requirements.
