用(yong)(yong)戶用(yong)(yong)水(shui)(shui)量一(yi)般是動態的(de)(de)(de)(de)，因此供(gong)(gong)水(shui)(shui)不足或供(gong)(gong)水(shui)(shui)過剩的(de)(de)(de)(de)情(qing)況時(shi)有發生。而用(yong)(yong)水(shui)(shui)和(he)供(gong)(gong)水(shui)(shui)之(zhi)間的(de)(de)(de)(de)不平衡集中反映在供(gong)(gong)水(shui)(shui)的(de)(de)(de)(de)壓(ya)力(li)(li)(li)上，即用(yong)(yong)水(shui)(shui)多而供(gong)(gong)水(shui)(shui)少(shao)(shao)，則(ze)壓(ya)力(li)(li)(li)低(di)；用(yong)(yong)水(shui)(shui)少(shao)(shao)而供(gong)(gong)水(shui)(shui)多，則(ze)壓(ya)力(li)(li)(li)大。保持供(gong)(gong)水(shui)(shui)壓(ya)力(li)(li)(li)的(de)(de)(de)(de)恒定，可使供(gong)(gong)水(shui)(shui)和(he)用(yong)(yong)水(shui)(shui)之(zhi)間保持平衡，即用(yong)(yong)水(shui)(shui)多時(shi)供(gong)(gong)水(shui)(shui)也(ye)多，用(yong)(yong)水(shui)(shui)少(shao)(shao)時(shi)供(gong)(gong)水(shui)(shui)也(ye)少(shao)(shao)，從(cong)而提(ti)高了供(gong)(gong)水(shui)(shui)的(de)(de)(de)(de)質量。

恒壓供(gong)水(shui)(shui)(shui)(shui)(shui)系(xi)統(tong)對(dui)于(yu)用戶(hu)是非常重要的。在(zai)生(sheng)(sheng)(sheng)產生(sheng)(sheng)(sheng)活供(gong)水(shui)(shui)(shui)(shui)(shui)時(shi)，若自(zi)來水(shui)(shui)(shui)(shui)(shui)供(gong)水(shui)(shui)(shui)(shui)(shui)因故壓力不足(zu)或(huo)短時(shi)斷(duan)水(shui)(shui)(shui)(shui)(shui)，可能影響(xiang)(xiang)生(sheng)(sheng)(sheng)活質量(liang)，嚴重時(shi)會影響(xiang)(xiang)生(sheng)(sheng)(sheng)存安全，如(ru)發生(sheng)(sheng)(sheng)火災時(shi)，若供(gong)水(shui)(shui)(shui)(shui)(shui)壓力不足(zu)或(huo)或(huo)無水(shui)(shui)(shui)(shui)(shui)供(gong)應，不能迅速滅火，可能引起(qi)重大經濟損失和人員傷亡。所以(yi)，用水(shui)(shui)(shui)(shui)(shui)區(qu)域(yu)采用正藝(yi)恒壓供(gong)水(shui)(shui)(shui)(shui)(shui)系(xi)統(tong)，能產生(sheng)(sheng)(sheng)較大的經濟效益(yi)和社會效益(yi)。
