What kind of water does the property use instead of tap water to collect water charges?

Groundwater. Tap water refers to the water purified and disinfected by the tap water treatment plant, which meets the corresponding standards and is used for people's life and production. The water charge of the property is not tap water, but groundwater. Domestic water is mainly extracted from rivers, lakes, groundwater and surface water through the water intake pumping station of waterworks. According to the national sanitary standard for drinking water, the waterworks are treated by sedimentation, disinfection, filtration and other processes, and finally delivered to various users through the water distribution pump station.
