The V-shape section plane can avoid blockage and make sure of the unimpeded water.

The consecutive slot have more open area, and it can reduce the speed of the water entering to avoid the sand entering the Water Well Screens under the great pressure, so it can filter sand better.

Meanwhile, the slot of Water Well Screens can change according to the real condition of the earth.
