Unified Facilities Criteria (UFC) 4-750-07 provides technical criteria and requirements for planning, designing, and constructing natatoria and outdoor aquatic facilities for recreational use. Alteration and renovation projects should update existing facilities to meet this criteria within budgetary constraints. This UFC is intended to promote innovative designs that are functional, economical, safe, aesthetically pleasing, and meet the expectations for modern aquatic facilities. Each design should satisfy the unique requirements of each Installation and at the same time be compatible with the local environment and specific site conditions.
