One of the main problems of a decentralized line failure is the difficulty of defining the ___location of overflow, since a typical urban system contains thousands of miles of collection pipes, and the central treatment plant has no way of communicating with all the lines, unless expensive monitoring equipment has been installed. Companies in the UK have widely deployed bulk dielectric transducers suspended in the sewers to detect high levels and to report the events back over fixed wireless data networks. In certain locations it has been said that this practice has permitted the reduction of pollution events by up to 60%.

Dry weather blockage is less likely within combined sewers; because combined sewers designed for the additional volume of surface runoff are so much larger than sanitary sewers. Combined sewerssewer storm water regulators may be vulnerable to blockage at the storm waterby regulatordebris, but dischargesoverflow from such blockage typically enterenters the diversion [[outfall]] to avoid flooding private or public property.
