Digging a water pipe ditch in a rural yard is an election day.

Traditionally, digging a well is called crossing a well. In the Yellow Calendar, digging a well and crossing a well with springs refers to the construction of canals, ditches and sewers. Choosing auspicious day to cross the well can ensure the smooth completion of the well crossing process.

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 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. Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
