8 The Committee was assigned the responsibility of developing physical, safety, chemical and bacteriological Standards for Swimming pools. The Standards are intended to serve as a guide for the Design of public Swimming pools; to encourage submission of plans for proposed public Swimming pools or their improvements; and to establish, as far as practicable, uniformity of practice among the several states. Because statutory requirements and legal authority pertaining to public Swimming pools are not uniform among the states, and as conditions and administration procedures and policies also differ, the use of these Standards must be adjusted to these variations. The terms "shall" and "must" are used where practice is sufficiently standardized to permit specific delineation of requirements, or where safeguarding of the public health and safety justifies such definite action.

9 Other terms, such as "should," " Recommended ," and "preferred," indicate desirable procedures or methods, with deviations subject to individual consideration. The Committee was also given the charge to develop an operations manual on Swimming pools. The Operation Section of the Standards is intended to serve as a guide to the operation of public Swimming pools; to supplement the Recommended Standards of Design ; and to establish, as far as practicable, uniformity of practice among the several states. The use of these operational Standards also must be adjusted for the differing statutory requirements, administrative procedures and policies of the various states. 12 PART 1. Standards FOR Swimming POOL Design DEFINITION AND SPECIAL POOL FEATURES OR USES DEFINITION - The term "public Swimming pool" as used in these Standards shall mean any artificial basin of water constructed, installed, modified or improved for the purpose of Swimming , wading, diving, recreation or instruction, and includes, but is not limited to, pools serving communities, subdivisions, apartment complexes, condominiums, clubs, camps, schools, institutions, parks, manufactured home parks, hotels, motels, recreational areas and water parks.

10 These Standards are not intended for application to private single-family residence pools which are used strictly for recreational purposes by the occupants and their guests. SPECIAL POOL FEATURES OR USES - Standards for unique features of spas, wave pools, zero-depth pools and water slides are provided in separate sections. Any pools used for other special purposes, such as therapy or competition, or those used by physically or mentally handicapped persons, require additional Design consideration and should be handled on an individual basis. Design features that are not specifically covered by these Standards shall be permitted only where it is demonstrated that adequate safety and water quality can be maintained, based on current technology and the best information available at the time.
