Any industrial exploitation that requires a large contribution of water for its operation and needs to be supplied from a river for this, it will be necessary to avoid all the solid elements that dragged by the water can damage any of the elements that make up the farm. In the case of a treatment plant or WWTP, the need will be given by establishing the first level of purification by mounting a solid screen that retains the largest elements that contain the flow to be treated.

For it, The most effective solution is to place a protection grid in the ideal place so that only water passes through its plates and all these solids remain in them..

A gate by itself would be enough to fulfill this function. in exchange for permanently needing the attention of a person day and night, that by means of a rake, manually clean the grate of everything that accumulated in it.

This hard and expensive task, even inhumane since emergencies do not have fixed schedules, it will be avoided by installing an automatic gate cleaner on the farm.
