Therefore, the secondary water supply is the most high-level water supply options. Whether the secondary water supply facilities according to the provisions of the construction, design and construction of the merits of the water supply is directly related to water quality, water pressure and water security, and the people of the normal and stable life is closely related. However, in the past in the country has not yet a complete technical standards for the secondary water supply projects, but in the "Building Water Supply and Drainage Design Code," the relevant sections of some of the requirements.
 In this case,
    Secondary water supply facilities mainly to make up for lack of municipal water supply line pressure to ensure that living, living in high-level population and the establishment of water. Compared with the raw water supply, the quality of the water supply is more susceptible to contamination, and the safety and reliability of the water supply has been widely concerned by the public.
 In the forthcoming implementation of the "standard", corresponding to the construction of water supply facilities construction projects, building height and the municipal water supply pipe network and the secondary water supply points made it clear that: all public building height of more than 12 meters, The secondary water supply facilities must be set independently, and shall not be mixed with the facilities such as fire fighting; the secondary water supply (such as water supply) shall not be mixed with other facilities; The water supply facilities must have a stable and reliable disinfection measures and anti-backflow of pollution measures; prohibited design, construction of buried or semi-buried water tank; for the secondary water supply (such as water supply), the water supply facilities should be designed with the main project at the same time, The total effective volume of the water tank should not exceed 36 hours of domestic water consumption, the volume of more than 50 cubic meters of water tanks must be divided into two parts: water tanks, water tanks, water tanks, water tanks, For the two cells, and can work independently.
