During the operational process of the water supply system in a housing estate,the tap water in the pipe networks flowed into the reservoir for a transit,which caused not only energy loss but also water overflow.This essay introduces its reform by combining the front and back pipe networks in the reservoir.Consequently,the electricity consumption has been cut down by 1,110,000kWh with a reduced running cost of 666,000 yuan annually.In conclusion,good energy conservation effects and economic profits have been gained.%某小区供水系统运行过程中,管网中的自来水流入水池中转,导致能量浪费,同时还有部分自来水从水池中溢流流失。通过对供水系统改造,将水池前后管网直接连接起来,自来水不再通过水池中转,每年为该小区实际节约用电量为111万kW.h,节约运行费用66.6万元,获得了较好的节能效果,并取得了一定的经济效益。
