Is the hospital's water storage tank good for the feng shui of the gate?

Yangzhai takes the main house gate as the Yangzhai gate, not the courtyard gate as the Yangzhai gate, which will of course serve as a reference for air intake. This courtyard is called "Tang Ming" in Feng Shui, namely "Suzaku Square". The owner of the mountain decided that water is the main wealth, so it is appropriate to have water. However, it should be noted that this water must be fresh water and running water, not sewage, dirty water or stagnant water.
