Abstract
There is described a sewer blockage monitoring system comprising a cluster of at least three in-sewer water level sensors, said sensors consisting of a reference sensor, an indicator sensor and a verification sensor, wherein each of the sensors is positioned in separate manholes; and the output from each of the sensors provides an electrical signal representing the level of fluid in the sewer system manholes wherein said electrical signal is capable of being analysed to provide an alert signal for blockage detected.
