In urban areas served by separate sewerage consisting of separate pipe systems it is not uncommon for misconnections to be made either accidentally or deliberately, whereby the wrong effluent is connected to the wrong sewer. The main focus of this problem has been on in-household appliances that are wrongly connected to separate surface water sewers, potentially leading to pollution of receiving waters and non-compliance with statutory water quality standards. This paper examines the available evidence to evaluate the potential scale, severity and cost of the problem in England and Wales in comparison to that reported from investigations in the United States. The particular difficulties associated with distinguishing specific sewage sources in the wastewater "cocktail" discharged at polluted surface water outfalls are reviewed. The deficiencies of existing legislation and enforcing compliance with respect to misconnections are also discussed and the pollution potential resulting from domestic misconnections is explored based on sampled data.
在由单独的管道系统组成的独立污水系统服务的城市地区，错误连接的情况并不罕见，无论是偶然的还是故意的，错误的废水都被连接到了错误的污水管。这个问题的主要关注点一直是错误地连接到单独的地表水污水管的家庭内的器具，这可能导致受纳水体受到污染，并且不符合法定的水质标准。本文审查了现有证据，以评估英格兰和威尔士与美国调查报告相比，该问题的潜在规模、严重程度和成本。审查了在受污染的地表水排放口排放的废水“混合物”中区分特定污水源的特殊困难。还讨论了现行立法的缺陷以及对错误连接的执行情况，根据抽样数据探讨了家庭错误连接造成的污染潜力。
