Abstract

Abstract

To realize the continuous and low-cost monitoring and assessment of extraneous water risk in urban sewage networks, this paper proposed a set of risk assessment methods based on integrated monitoring of water supply and drainage systems. The risk level was reflected by two indicators:extraneous water proportion R and grade frequency P, which can capture the spatial and temporal distribution of extraneous water. The methods were applied to the risk assessment of extraneous water in an area of City W in south China. The study area was divided into three sub-catchments by four plant pumps and three key monitoring nodes. The analysis results of data in March 2022 showed that the extraneous water risk level of subcatchment-Z1 was L2 (relatively high), the overall region and subctchment-Z3 was L3 (high), and the subcatchment-Z2 was L4 (very high). In April, the results of sub-catchments remained unchanged except that the overall region was reduced to L2. Compared to traditional methods, this method can output reliable conclusions, realize the risk distribution analysis of extraneous water with low cost, and has practical significance for improving the efficiency of sewage network management.
