UFC 4-750-0720 April 2020FOREWORDThe 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 Command (NAVFAC), and Air Force Civil Engineer Center (AFCEC) areresponsible 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, for implementation of new issuances on projects.AUTHORIZED BY:GEORGE O.

UFC 4-750-0720 April 2020UNIFIED FACILITIES CRITERIA (UFC)NEW DOCUMENT SUMMARY SHEETDocument: UFC 4-750-07, Aquatic FacilitiesSuperseding: Air Force Pamphlet (AFP) 88-52 Swimming Pools, dated 1984.Description: This UFC 4-750-07 provides minimum requirements for natatoria, outdoorswimming pools, wading pools, spas, spray grounds, pool decks and all other functionalbuilding areas associated with recreational aquatic facilities.Reasons for Document: This document provides minimum unified requirements andcoordinating guidance for planning, designing, constructing and renovating recreationlevel aquatic facilities and will enhance DoD aquatic recreation facilities by: Providing application of existing aquatic model codes and industry standards toDoD facilities. Creating an interactive space program to quickly develop sizes of functionalareas for each Service. Providing material criteria specific to aquatic facilities to increase facility longevityand decrease maintenance.Impact: There are negligible cost impacts. However, the following benefits should berealized. Elimination of ambiguities that could lead to design and construction conflicts. Enhanced communication between disciplines involved in the design of aquaticfacilities. The incorporation of existing model codes and industry standards improves theease of updating and revising this reference document as technologicaladvances occur in the industry.Unification Issues: Army, Navy and Air Force have Service-specific documents related to design,construction and operation of natatoria and outdoor swimming pools. There aredifferences noted in this document that are attributed to specific functionalspaces or systems. Service exceptions to the requirements of this UFC arewritten into the applicable section of the document.

UFC 4-750-0720 April 2020CHAPTER 1 INTRODUCTION1-1BACKGROUND.UFC 4-750-07 was originally drafted in 2006 by the Air Force to develop a new unifiedfacility criterion for use in the design of aquatic facilities primarily used for recreation;however, the draft document was not finalized for implementation. Continueddevelopments in the aquatic industry have resulted in advances in disinfection andrecirculation technology, the introduction of unique programming and design elements,the passing of the Virginia Graeme Baker Act, development of the Model Aquatic HealthCode, and development of the International Swimming Pool and Spa Code as part ofthe International Building Code. UFC 4-750-07 provides applicability of model buildingcodes and government-unique criteria for aquatic facilities (including swimming pools,natatoria, non-medical spas, wading pools, spray grounds and pool decks), typicaldesign disciplines and building systems, as well as for accessibility, antiterrorism,security, sustainability, and safety.1-2PURPOSE AND SCOPE.Unified Facilities Criteria (UFC) 4-750-07 provides technical criteria and requirementsfor planning, designing, and constructing natatoria and outdoor aquatic facilities forrecreational use. Alteration and renovation projects should update existing facilities tomeet this criteria within budgetary constraints. This UFC is intended to promoteinnovative designs that are functional, economical, safe, aesthetically pleasing, andmeet the expectations for modern aquatic facilities. Each design should satisfy theunique requirements of each Installation and at the same time be compatible with thelocal environment and specific site conditions.Customized, individual solutions meeting the needs of each project is the primaryobjective of this UFC. Use this UFC in conjunction with Department of Defense (DoD)criteria, service-specific documents, aquatic industry publications, and regulatoryagencies, as applicable. Obtain additional information on the unique program anddesign requirements of local projects from the Installation points of contact.1-3APPLICABILITY.This UFC applies to all military services and contractors involved in planning,programming, design, and construction of aquatic facility projects, including additions,alterations, and renovation projects worldwide.1-4GENERAL BUILDING REQUIREMENTS.Comply with UFC 1-200-01. UFC 1-200-01 provides applicability of model buildingcodes and government unique criteria for typical design disciplines and buildingsystems, as well as for accessibility, antiterrorism, security, high performance andsustainability requirements, and safety. Use this UFC in addition to UFC 1-200-01 andthe UFCs and government criteria referenced therein.1

The publication dateof the code or standard is not included in this document. In general, the latest availableissuance of the reference is used.1-8BEST PRACTICES.APPENDIX A identifies background information and practices for accomplishing certainaquatic facility design and engineering services. The Designer of Record (DoR) isexpected to review and interpret this guidance as it conforms to criteria and contractrequirements, and apply the information according to the needs of the project. If a BestPractices document has guidelines or requirements that differ from any UFC or theUnified Facilities Guide Specifications (UFGS), the UFC and the UFGS must be given ahigher order of precedence.1-9AQUATIC FACILITY CLASSIFICATIONS.Two general types of aquatic facility classifications include outdoor pools and natatoria(indoor pools).1-10OPERATIONAL IMPLICATIONS.Procedures for Installation level recreation programs, aquatic activities, operation, andmaintenance of pools, including natatoria, are provided in the following documents: AFI 34-101 AFI 32-1067 AFMAN 48-114 UFC 3-230-02 MAHC TB Med 575 TM 5-662 Technical Criteria for US Army Physical Fitness Facilities2

UFC 4-750-0720 April 2020CHAPTER 2 PLANNING AND PROGRAMMING2-1PLANNING CONSIDERATIONS.Chapter 2 provides requirements and information for planning and programming DoDaquatic facilities and the infrastructure to support them. Aquatic facility developmentplanning and the programming of facility space are different for every project dependingupon the unique factors regarding each Installation. Consider local requirementsconcerning building programs, design criteria, technical systems and the adequacy ofexisting facilities to meet current and future needs.Operating Policies.Selected programs and spaces for each facility may vary widely depending on theanticipated operating policies of each facility. Determine early in the planning processthe preferred operating procedures for the types of programs and activities to beprovided.Programs and Activities.Analyze the activities to be provided to determine facility requirements. Coordinate withInstallation personnel to identify specific requirements for the programs and activitiesthey plan to implement (e.g. open swimming, diving, water polo, wading, aquaticfitness/therapy, swimming/life
