How to address the safety hazards associated with secondary water supply in residential areas?

Thread Content

With the development of cities, buildings are becoming taller and taller, and secondary water supply has become an essential part of urban water supply. Compared to raw water, secondary water supply presents more safety risks. So how can these issues be addressed? Secondary water supply is a concept that most people are not yet familiar with. It refers to a method in which water suppliers store and pressurize the potable water from the city’s centralized supply system, and then deliver it to users through pipelines. This approach is typically used to address the issue of low water pressure among residents. Regarding the resolution of safety hazards, the main issue is the cleaning of water tanks or pools; according to regulations, these tanks must be cleaned at least twice a year, and this cleaning must be carried out by qualified professional firms. Then drain the water inside, remove any impurities, disinfect it, refill it with clean water, and add a food-grade drinking water disinfectant to it for further disinfection. For manufacturers of water supply equipment in related industries, it is recommended to hire professional firms and experts to clean and disinfect water tanks as well as secondary water supply systems, so as to ensure a reliable supply of water for daily use.
