What is the water in the sink in the service area?

The water in the sink in the service area is tap water, which can't be drunk directly. It must be boiled to become drinking water. Public water is tap water, and there is no classification. It is the same for families, enterprises and institutions or fire fighting. Some enterprises with large water consumption will exploit groundwater for their own use, and some people will use domestic wastewater for family toilets. These are individual phenomena.

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. Domestic water is mainly extracted from rivers, lakes, groundwater and surface water through the water intake pumping station of the waterworks, treated by sedimentation, disinfection, filtration and other technological processes, and finally delivered to various users through the water distribution pumping station.
