Human beings can not survive without water. Owning to a severe water pollution and an exacerbating water environment imperiling people’s drinking water, it is now critical to protect drinking water sources. The existing laws lack effective protection and have a unfit punishment for destroying water sources, and pay inadequate attention on drinking water in rural areas and underground water. This paper, based on the current situations regarding drinking water sources, presents some suggestions that the future legislations or laws modification shall be based on sustainable development, enhance protection on water sources in rural areas and underground water, combine environmental protection and eco-construction, intensify the punishment against drinking water pollution, and establish an eco-compensation system, all this contributing to an effective protection of Human being’s water sources.
