摘要
为补救我国城镇供水水压的不足,各地采取了不少措施。作者调查分析后认为:在水压普遍不足的城镇,采用分区分压供水可减少阻力,降低电耗;新区和卫星城宜采用集中加压方式;高层建筑和个别用户可采用单独加压方式;城市管网水压白天能上三楼,夜间可至屋顶地区,设置屋顶水箱仍是一种简便有效的方法;新辟水源、扩建水厂、改造城市管网是根本解决城镇供水的有效方法,但涉及面广,一次投资较大。
Extensive efforts have been made to relieve the underpressure of water supply systems in many cities and towns.The solution to build new water utilities may be very effective but does often involve prohibitively high cost.After an investigation being made,the author recommends the following schemes:to operate different pressures for different zones in the case where underpressure is prevailing for the whole city or town,which can result in a lower pressure drop and power saving;to exert the central pressure boost for newly developed districts and satellite towns;to use individual pressurization for highrise buildings and the users with special requirements;and to benefit simply from the installation of roof water tanks for the city or town where the water can reach to the third storey of buildings daytime and to the roof at night under the pressure of municipal pipelines.
