At present, most of the tap water consumed by domestic urban residents comes from tap water stored in high-rise roof water tanks, which are basically gray brick structures. During the storage of tap water in high-rise water tanks and other containers, it is very easy to breed plankton and microorganisms. Surveys have shown that nearly a hundred species of algae grow and reproduce in high-rise water tanks, and some algae produce toxins. The total number of bacteria in the water tank exceeds the standard rate by 100%, the number of coliform bacteria exceeds the standard rate by 97.6%, and the qualified rate of water chroma is extremely low.

In order to ensure the water quality of the secondary water supply, the only way at present is to regularly clean manually. During manual cleaning, the water in the water tank is often drained earlier, causing waste of water resources, and at the same time, it is necessary to stop the water supply to the residents, which brings inconvenience to the residents. In fact, due to management and other issues, the vast majority of water tanks have not been cleaned in time, or even have not been cleaned all year round.

The safety of drinking water for urban residents has become a livelihood issue that is widely concerned by the society, the government and the public. There have been stainless steel water tanks in the domestic market. The existing stainless steel water tanks are washed with high-pressure water and cleaning agents to clean the water tanks. The cleaning time is generally set in the middle of the night when the user’s water consumption is the smallest, but the water problem has not yet been solved. The problem of wastage, and cleaning agent needs to be added regularly during the cleaning process, which has a certain negative impact on water quality, and it is also inconvenient to use in old urban areas where the pipe network has a small pressure-dependent capacity.
