摘要：

Based　on　the　extended　period　simulation　of　EPANET　software,　and　a　calculation　method　on　leakage　modeling　is　proposed,　the　aim　of　the　paper　is　to　present　the　variation　pattern　of　water　consumption,　water　loss　and　the　benefits　yielded　by　pressure　management　during　24　hours　on　the　basis　of　the　relation　among　leakage,　consumption　and　pressure.　The　results　are　that,　if　it　is　assumed　that　the　inlet　pressure　of　DMA　is　reduced　from　39m　to　31m　through　PRV,　the　average　daily　water　consumption　and　water　loss　are　respectively　reduced　10.83%,　20.52%,　and　the　average　pressure　of　the　critical　point　is　reduced　21.13%,　then　the　quantity　of　daily　water　loss　and　consumption　saved　by　pressure　management　are　great,　which　will　produce　the　great　economic　benefits　annually.　©　ASCE　2013.
