Background: Water is the most valuable environmental factors that has essential role in life and human health. A quick review of the Islamic sources shows that optimal use of this gift of God has always stressed by infallible Imams. By counting twelve types of water, Muslim jurists have tried, depending on different climatic conditions, on the one hand to show the right water consumption to the public and the other hand to prevent its waste and pollution by determination of religious indicators. The main question in ethical- juridical study water resources productivity is that weather we can create a significant and logical relation between bioethics principles and religious teachings connected to environment? In this study we try to present ethical - religious model in conservation and utilization of Water as one of the natural environmental factor by using the juridical resources.Method: In this descriptive and library research we've attempted to study the position of Justice and non-maleficence as two ethical principals in religious teachings after explaining the concepts and principles of bioethics and then based on that we will evaluate quality and outcomes of utilization of resources water.Data: This review reflects on the other hand, the principals of Bioethics are universal and approved by Islamic leaders because of intellectual origin and the other hand, centuries before formulating these principals, Muslim jurists have tried to express human tasks in face of environmental resources including surface and subsurface water in form of statements of environmental fegh, with emphasis to the religious teachings (the Quran and Sunnat) and attention to them.Conclusion: Principles of justice and non-maleficience are the two principles of Bioethics governing the utilization of environmental resources, including water resources, and any use of these resources, regardless of it, will be immoral and also unlawful.
