UFC 3-240-011 May 2020Change 2, 1 January 2021FOREWORDThe Unified Facilities Criteria (UFC) system is prescribed by MIL-STD 3007 and providesplanning, design, construction, sustainment, restoration, and modernization criteria, and appliesto the Military Departments, the Defense Agencies, and the DoD Field Activities in accordancewith USD (AT&L) Memorandum dated 29 May 2002. UFC will be used for all DoD projects andwork for other customers where appropriate. All construction outside of the United States isalso governed by Status of Forces Agreements (SOFA), Host Nation Funded ConstructionAgreements (HNFA), and in some instances, Bilateral Infrastructure Agreements (BIA).Therefore, the acquisition team must ensure compliance with the most stringent of the UFC, theSOFA, the HNFA, and the BIA, as applicable.UFC are living documents and will be periodically reviewed, updated, and made available tousers as part of the Services’ responsibility for providing technical criteria for militaryconstruction. Headquarters, U.S. Army Corps of Engineers (HQUSACE), Naval FacilitiesEngineering Systems Command (NAVFAC), and Air Force Civil Engineering Center (AFCEC)are responsible for administration of the UFC system. Defense agencies should contact thepreparing service for document interpretation and improvements. Technical content of UFC isthe responsibility of the cognizant DoD working group. Recommended changes with supportingrationale may be sent to the respective DoD working group by submitting a Criteria ChangeRequest (CCR) via the Internet site listed below.UFC are effective upon issuance and are distributed only in electronic media from the followingsource: Whole Building Design Guide web site http://www.wbdg.org/ffc/dod.Refer to UFC 1-200-01, DoD Building Code (General Building Requirements), forimplementation of new issuances on projects.AUTHORIZED BY:CHRISTINE T.

The use of industry standards and federal codesaided in the consolidation of these criteria documents. This revision updates technicalrequirements, industry standards, and maximizes uniformity among Tri-Servicerequirements. Appendix C contains a complete list of referenced wastewaterrequirements and Appendix B contains a complete list of referenced best practices.Reasons for Document: This revised UFC updates wastewater collection and treatment criteria that waspreviously contained in multiple criteria documents and efficiently consolidatesthem into a single UFC. Establishes technical requirements by maximizing the use of industry standardsto meet DOD requirements. Reorganizes the content to align with industry standards. Coordinates criteria requirements in other core and specialty UFC criteriadocuments.Impact: This revision will have minimal impacts on design cost.Unification Issues: FC 1-300-09N is referenced for Navy design procedures.

UFC 3-240-011 May 2020Change 2, 1 January 2021CHAPTER 1 INTRODUCTION1-1BACKGROUND.People have used different terminology to describe wastewater treatment facilities formany years. Today people use terms such as sewage treatment plant, wastewatertreatment plant, wastewater treatment facility, or publicly owned treatment works todescribe domestic wastewater treatment facilities. Recommended Standards forWastewater Facilities uses the terms wastewater facilities or wastewater treatmentfacilities. The EPA generally uses the terms municipal wastewater treatment facilitiesand wastewater treatment facilities. In recent years, Water Environment Federation(WEF) started using the term water resource recovery facilities (WRRF) to describedomestic wastewater treatment facilities since the wastewater industry is becomingmore focused on resource recovery. These terms apply only to domestic wastewatertreatment. This terminology should not be used interchangeably with industrialwastewater treatment facilities.1-2PURPOSE AND SCOPE.This Unified Facilities Criteria (UFC) provides requirements for domestic wastewatercollection, domestic wastewater treatment, industrial wastewater collection, andindustrial wastewater treatment for the Department of Defense (DoD).1-3APPLICABILITY.This UFC applies to service elements and contractors involved in the planning, design,and construction of permanent DoD facilities worldwide. It is applicable to all methodsof project delivery and levels of construction. The contingency operation wastewaterflows are applicable to facilities supporting military operations.1-4GENERAL BUILDING REQUIREMENTS.Comply with UFC 1-200-01, DoD Building Code. UFC 1-200-01 provides applicability ofmodel building codes and government unique criteria for typical design disciplines andbuilding systems, as well as for accessibility, antiterrorism, security, high performanceand sustainability requirements, and safety. Use this UFC in addition to UFC 1-200-01and the UFCs and government criteria referenced herein.1-5CYBERSECURITY.All control systems (including systems separate from an energy management controlsystem) must be planned, designed, acquired, executed, and maintained in accordancewith UFC 4-010-06, and as required by individual Service Implementation Policy.1
