【正文】 ater resources With the continuous development and promotion of City Water Supply Networks, the capacity and reliability of municipal water supply are greatly improved. When municipal waterline work can satisfy the demand of fire water during fire hazard, the indoor fire pool was suggested to be canceled and directly draw water from municipal water pipe works. VII. DEVELOP AND PROMOTE THE TECHNOLOGY ABOUT UTILIZATION OF RECLAIMED WATER AND RAINWATER The water saving of building means not only to reduce the need of water, but also to increase the available water. In the regions with severe watershortage, to enhance the efficiency of usage of reclaimed water and rainwater is an important part of watersaving. Reclaimed water is nopotable water of kinds of drainage water after processed plying with the water quality standard. It can be used as toiletflushing, urban greening, vehicleswashing, fire, etc. within life, the municipal administration, the environment. According to the data, after use of waterreuse system, residential water consumption will save 30% 40%。 mercial residential district can save 70%。 for general residential munity it can save 30% [5]. With the development of city and the improvement of living standards, the city’s water consumption will continue to increase. In the area with the shortage of available water resources, the price of water will maintain a certain growth rate, thus the construction of the second water resource is economically viable. It is the effective measures for reclamation of sewage and water saving, it also is the inevitable direction of the development of water saving. Similar to reclaimed water, rain recycling is the rainwater through collection, storage, handling, and to be used as miscellaneous water. Since 1980, Europe, Japan and other countries, one after another, have carried out investigation about rainwater collection and utilization. Research shows that, if rainwater collection and utilization system is established, the collection, processing and recycling of rainwater nearby, used for flushing toilet, cleaning vehicles, afforesting, spraying streets, or as a supplement for 671670landscape water and river etc, will save considerable water. But not every place is appropriate for setting the system. If rainfall is not high enough or the water consumption is not large, the cost recovery of the system will be slow [6]. Therefore, according to local rainfall characteristics, water price, construction cost, operation cost and water consumption, the adoption of the system should be after careful consideration. VIII. CONCLUSION Water saving is a career in the contemporary era that will benefit future generations. It is system engineering. We should insist on the bination of the whole people’s water saving awareness and technical watersaving。 watersaving should be first. Within the bearing capacity of water resource and water environment, on the premise of ply the law of social development and water supply, we ought to carry out propaganda education about the consciousness of watersaving, perfect relevant legal system, prehensive use various conservation measures, and develop new technology. These methods can not only alleviate the contradiction between urban water supply and demand in a certain extent, also can reduce wastewater, and achieve good social and environmental benefits.
