How to do the secondary water supply property in the community?

1) The concept of secondary water supply:

Secondary water supply is a set of pressurization technology to ensure the water pressure of high-rise users. Tap water used by residents living in high-rise buildings is first delivered to the secondary water supply tank, and then delivered to every household through measures such as pressurization.

(2) The purpose of secondary water supply in the community:

The tap water pipes in old residential areas are old, many of which are cast iron pipes and galvanized pipes that have long been eliminated, which are easy to leak and waste water resources. The reconstruction of secondary water supply is mainly to replace old pipes and water tanks.
