ABSTRACT
MIKE+ model is used to design the collection system of Malappuram city situated at 54 km south west ofCalicut and 90 km North West of Palakkad of Kerala state. The shapefile of the study area, SRTM 30mDigital Elevation Model, and rainfall data for the years 2017-2020 were collected and added as layers inMIKE+. Through manhole digitization followed by link creation, catchment delineation, catchmentconnection, and various boundary conditions, the rainfall-runoff model and catchment discharge byrational formula were determined. In Malappuram city, there are nine outlets, majority of sewers aredelivering water to outlets at nodes 1156, 2344, and 2955 to reduce the burden of waste. According to thediameter of the manholes, the collection system was observed to be overdesigned, but it is capable ofcollecting all wastewater from each residence and catchment runoff to outlets without the need of pumpsby gravity flow. In future perspective, if the water level exceeds the set critical level, mainly for thetrunks sewer A and G, it will be a point of concern and requires attention.
