long time water is moveless and some people does not use the water through healthy ways so the place will have a contamination. That is why people stopped using them. On the other hand, the study proposes some sustainable design solutions for these problems, which can solve this issue and people, can continue using the rainwater in a face of fresh and healthy way. As soon as most of the water requirements are supported by cisterns, it is necessary to solve human health hazards in cisterns. Sustainable Solution: The best way to protect the water from microbe and bacteria is water filtration idea. Water filter machine can create movement in the water in addition to kill the bacteria and hazards inside the water. To activate the filter electricity is the major element, which is required but the lack of power, is another problem, which also requires another solution. As mentioned before, Evaz has a strong solar power, which has not been used until today. Using solar panel to produce electricity for those water cisterns will be great idea. As per the research on different kind of solar panels, it has been discovered that with installation of a solar panel on one cistern can produce electricity power to nine other cisterns as well. Radiation of sun in the south orientation is more powerful than any other orientation (Fig.15).
