Can property companies in Beijing extract groundwater as drinking water?

At present, the groundwater in Beijing has been overexploited, and the groundwater level is about 50 meters deep. The government has strict control over groundwater exploitation, and enterprises or individuals are not allowed to dig wells to extract groundwater privately. If you want to dig a well to get water, you need to contact the water conservancy department. Otherwise, it is illegal to take groundwater without authorization. In addition, the overall quality of groundwater in Beijing is also poor, and the general indicators such as total hardness and nitrate are relatively high. If the water is not treated, it may not meet the drinking requirements.
