为了不让自来水表计量,让水龙头里的水一滴一滴地滴到盛水器皿中,积少成多后再使用。一些自作聪明的人就这样“巧用”自来水,以为节省了不少水费开支,殊不知这种窃水行为,不仅给国家造成损失,而且还会危害人体健康。据了解,“巧用水”会造成自来水在管道或容器中存留,形成“死水”。省计量认证合格部门按照国家《生活饮用水卫生规范》,对这种“死水”和自来水进行对比实验,发现“死水”在氨、硝酸盐、亚硝酸盐、THM(三卤甲烷)等指标上均比新鲜自来水高0.2至1倍。
In order to prevent the water meter from measuring, let the water in the faucet drop by drop to the water container, add up and use it. Some clever people on such “clever use” of tap water, in the hope of saving a lot of water expenses, not knowing that this theft behavior, not only caused losses to the country, but also endanger human health. It is understood that “clever use of water” will cause tap water in the pipeline or container to survive, the formation of “stagnant water.” Provincial Metrology Accreditation Department in accordance with the national “drinking water health norms” on this “stagnant water” and tap water comparative experiments found that “stagnant water” in the ammonia, nitrate, nitrite, THM (trihalomethanes) and other indicators 0.2 to 1 times higher than fresh tap water.
