The purpose of the environmental health is to create and maintain the ecological conditions that will promote health and thus prevent disease. The large number of people around the world still do not have access to adequate water and sanitation, drainage and solid waste disposal services providing sufficient evidence that conventional approaches to environmental sanitation are unable to make a significant improvement. One of the essential elements of the public health care is safe drinking water and sanitation.Proper sanitation promotes health, improves the environment and thus, the quality of life in a community.
