[4] Li Changyu, Discussion on Building Water Supply and Drainage Engineering and Water Saving, Wateramp。 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。 when the municipal water supply pipeline is branched or there is only one water inlet pipe(except for second residential building). The volume of fire pool should meet the requirements of indoor and outdoor water use within the fire duration time. In this way, the volume of fire pool of every highrise building is very large by calculated, the volume will be from several hundreds of cubic meters to more than several thousand cubic meters. Generally the construction of fire pool has two ways, namely the bination of fire pool and drinking water tank, the construction of fire pool independently. In the case of bination of fire pool and drinking water tank, since most buildings’ fire waterstorage is much greater than drink waterstorage, drink water stays too long in tank to result poor water quality because of the exhaust of residual chlorine. Therefore，drinking water tank and fire pool should be established separately in the new building construction. Not only the construction of fire pool independently occupies valuable building space that costs a lot of construction investment, but also fire water is easy to be smelly because of fire water’s lower frequency of use. In order to ensure fire water quality, we have to replace fire water regularly which results in waste of water resource. Therefore, I put forward some suggestions about the construction of fire pool. A. Adapt the regional cooperation mode of fire pool With the development of city construction, the density of highrise buildings grows quickly. Government departments should coordinate the relevant units and departments to promote that the adjacent buildings in the same block share the same fire pool and establish shared control center according to the actual situation. The design of fire pool should be accordance with the maxim fire water volume of building use. Relevant beneficiaries undertake certain cost according to the scale o
