This paper presents the design and prototype implementation of USenSewer, an automated sewerage management system that uses Arduino microcontroller coupled with an ultrasonic sensor, a NRF module and a GSM module to automate the routine checkup and removal of drain blockage vital for the continuous waste water flow in the big cities. The proposed system consists of three main components; the blockage detection system which is placed inside the drain, the blockage removal system which is placed above the ground level and a control center which controls and coordinates the collection of waste materials placed by the first two components. Several pilot installations of the system in the city of Dhaka have shown that the proposed system significantly outperforms the state-of-the-art manual systems prevailing in the city from the scalability, flexibility and economic point of view.
