管道在输水过程中的跑冒滴漏是很大的。据分析,年久失修,管道破裂而漏水,市区管路的漏水率常为8%,工厂区管路的漏水率为10%~20%。在第三世界的一些城市,因水管生锈或接头有问题,60%的自来水被漏掉了。菲律宾的马尼拉市,自来水总管的漏水率达到58%。而管理较好的新加坡,水管漏水率仅8%。管理人员疏忽大意,忘记关闭浇灌庭院的水管龙头,形成的长流水已司空见惯。家家户户水龙头未关紧而滴嗒漏水,也不可小瞧。
Plumbing in the process of water transmission is great. According to the analysis, a long time disrepair, pipeline rupture and leaking, urban pipeline leakage rate is often 8%, leakage rate of 10% to 20% of the factory district pipeline. In some cities of the Third World, 60% of tap water is missing due to rusty pipes or connectors. Manila, Philippines, water mains leakage rate of 58%. In Singapore, where water quality is well managed, water leakage rate is only 8%. Management negligence, forgetting to turn off the water pipe leading to the yard, the formation of long flowing water has become commonplace. Every household faucet is not tight and drip drip, it can not be underestimated.
