This work has showed that gray water can be used in irrigation with great success. It includes the explanation of how water recycling will save water for irrigation and agriculture use, reduce the costs of constructing purification plants, and add natural filters to the environment. It also aspires to invite companies to reduce the proportion of phosphate and other harmful substances in the composition of soap. In addition, it is possible to reduce the amount of suspended solids in a gray water by installing filters on the washing machines themselves, so that the volume of problems in the plankton is reduced at the refineries. It was found that the decrease in the consumption and rationalization of electric energy was observed for other purposes using the solar cell system, which is considered as a source of power supply system.
