The occurrence of environmental crises and resource scarcity have created deep concerns at various levels of human societies, which need to be addressed by the inclusion of environmental criteria in development activities. There is a two-way relationship between man and nature. Humanity exploits nature for its own interests and tries to control the environment. It has invented ways and means to achieve its goals and improve its well-being. Its effects on human life are profound and not only affect the human welfare state, but also It may create conditions that are contrary to human welfare. Here is the need for environmental assessment studies, including the assessment of the environmental impact of the development. Water and sanitation projects are no exception to this and their environmental impacts should be studied and evaluated. Many of the plans that look at environmental protection at first glance may seem, but in the long run have created unsolved environmental problems.
