It is not good to build a shed outside the hospital to run water. According to relevant data, in the process of building sheds, discharging running water directly to the outside of the courtyard may have a certain impact on the surrounding environment, especially in rainy season or rainy weather, running water may form stagnant water, resulting in slippery ground and increasing the risk of pedestrians falling. In addition, if tap water contains chemicals or other pollutants, it may also pollute the local environment and water quality, and adversely affect the lives of surrounding residents. Therefore, it is suggested that in the process of building sheds, the running water should be controlled as much as possible to avoid directly discharging water outside the courtyard.
