Purpose

With the acceleration of global urbanization and the improvement of public health awareness, swimming pools, as important public facilities and leisure venues, have continued to grow in quantity and scale. According to statistics from the World Health Organization (WHO), there are more than 50 million swimming pools worldwide, with an annual water consumption of 40 billion cubic meters. However, traditional swimming pool water circulation systems have problems such as fragmented technologies and lack of standards: on the one hand, some outdated system designs lead to water waste, and the abuse of chemical agents causes hidden dangers to water quality and safety; on the other hand, the international standard system lacks systematic guidance documents for swimming pool water circulation systems. Existing ISO standards (such as the ISO 20468 series) focus on general disinfection requirements for water treatment technologies but do not cover the particularities of swimming pool scenarios, such as circulation cycles, disinfectant control, and intelligent monitoring. Therefore, formulating special international standards for swimming pool water circulation systems has become an urgent need to ensure public health and promote the sustainable development of the industry.

This standard intends to fill the gap in the international standard system and, for the first time, build a technical framework covering the entire chain of design, construction, operation, and maintenance. By integrating advanced global technologies and formulating universal technical clauses, it will clarify the composition, content, and key points of the water circulation system, as well as key parameters such as circulation cycles, disinfectant control, and intelligent monitoring, so as to promote the development and transformation of swimming pool water circulation systems towards intelligence and low carbonization.

By strengthening international consensus on swimming pool water circulation systems, this standard will significantly improve public health safety and resource utilization efficiency, promote the global application and popularization of applicable technologies and methods for swimming pools, drive the standardization and globalization of the swimming pool industry, assist in the construction of "Belt and Road" public facilities, provide systematic solutions for the upgrading of global swimming pool-related water treatment technologies, and realize the goals of human health and sustainable development.
