UFM 3-230-02 is the Unified Facilities Manual (UFM) for Operation and Maintenance: Water Supply Systems, current as of 5 February 2026 [UFM 3-230-02 FOREWORD].

Key points:

UFM 3-230-02 provides non-mandatory, informational guidance to help users understand and apply Unified Facilities Criteria (UFC) requirements. It is designated "For Information Only" (FIO) and shares operational procedures, maintenance practices, and practical examples supporting effective implementation during water system operations and maintenance activities [UFM 3-230-02 FOREWORD].

The manual replaces UFC 3-230-02 (Operations and Maintenance: Water Supply Systems, 10 December 2019) and all subsequent changes [UFM 3-230-02 1-1].

It provides general technical guidance for operating and maintaining potable water systems fit for human consumption (FFHC) at fixed military installations, and is supplemental to site-specific O&M manuals provided for each installation [UFM 3-230-02 1-2].

The manual covers filter media management, backwash operations, and tank inspection procedures referenced in PACAF guidance [PACAFMAN 32-1067 para 4.3.4.2.1].
