Swimming pools are engineered water-retaining structures designed for recreation, training, therapy, and aesthetic purposes. In urban and institutional contexts (such as campuses, TOD zones, and recreational complexes), pools contribute to public health, social interaction, and urban livability. Proper design and construction ensure structural safety, water hygiene, user comfort, and long-term durability.
This specification outlines the standards and procedures for planning, designing, constructing, and maintaining swimming pools, incorporating structural, hydraulic, mechanical, and safety aspects.
