碩士 === 國立宜蘭大學 === 機械與機電工程學系碩士班 === 102 === Currently the pressure management method about the water leakage rates decline advocated by the International Water Association (IWA), every country of the world compliance it as a standard, its research and practice primarily in the water supply side (water corporation company), but little interest to explore for the user side (clients), Just as Nemanja Trifunović had proposed “some areas the reservoir combine the communication system can increase water distribution stability”, and use cumulative water demand curve to discuss with the storage capacity of the reservoir, he believes the 20-40% peak water demand per day is sufficient. This thesis has explored the effective capacity of 0.9 m3 roof tanks, that enough to supply a family of five with 1.2 daily water consumption, therefore the area’s roof tanks has combined with the communication system, that highest efficiency of water distribution stability can be achieved 4.8 times the reservoir. The outflow and inflow tap water velocity is low in roof tanks have poor mixing and circulation, coupled with excessive detention time (long water age) that produce deterioration of the quality of the water in roof tanks. This thesis has completed the domestic water research and implement method, just wait for the combination between the area’s roof tanks and water company through the communication system to build a truly and completely wisdom pressure management network, then considerable economic benefits can be achieved.
