Testing the piping of a new hospital showed that the drinking water was contaminated with Pseudomonas aeruginosa. Because of pollution the plumbing system was treated with oxidizing biocides and air-water flushing for several times, unfortunately without stopping the bacterial recontamination. The reasons were firstly stagnation due to dead legs in the piping system, oversized pipes, very low water exchange rates and the installation of a catch water system, secondly low flow velocity because of low water pressure. After these sources of recontamination had been repaired, chlorine dioxide sanitization could be stopped successfully

对一家新医院的管道系统进行检测发现，饮用水被铜绿假单胞菌污染。由于污染，该管道系统多次使用氧化型杀菌剂进行处理并进行气水冲洗，但遗憾的是，细菌再污染问题并未得到解决。原因一是管道系统中存在盲管、管道尺寸过大、水交换率极低以及安装了集水系统导致水停滞，二是水压过低导致水流速度较慢。在修复这些再污染源头后，二氧化氯消毒得以成功停止。
