Generally, the depth of the common scene pool is 0.6 ~ 0.8m. The reason for this practice is to ensure the swallowing depth of the suction port of Hefei rockery fountain, and the pool bottom is a whole plane, which is also convenient for the device construction and protection of pipeline equipment in the pool.

As long as the shallow butterfly tank with hydrophilic characteristics is planned, the suction pit or pump pit can be selected. The water depth of 0.6 ~ 0.8m actually has great insecurity.
Similarly, in the planning of children's play pool, the depth generally selected is about 0.3 ~ 0.6m. Once children fall into the scene pool, it will be very risky. We think the more suitable water depth is 0.2 ~ 0.4m.
Another advantage of this is that when the water turbidity is slightly high, it still feels clear to the bottom. The top surface of the pool wall shall be available for tourists to sit down and rest. The height from the top surface of the pool wall to the ground is generally 0.30 ~ 0.45M. Except for the artificial lake, the water surface should be higher than the ground. If the water level is low, it will feel like a deep pool.
Starting from the hydrophilic point of view, the more appropriate standard is that the distance between the water surface and the top surface of the pool wall is 0.2m, which is more reasonable. The submersible pump pit or water pump suction port only needs to be partially deepened to meet the water absorption conditions. A grate can be set on the surface of the pump pit to cover the equipment and act as a grille to prevent the inhalation of large particle impurities. Starting from a beautiful point of view, the exposed pipeline equipment on the surface of the pool should be reduced as much as possible, especially the straight overflow pipe orifice, which will produce great drainage and suction sound when the water surface rises.
