Sewage blockages are quite common at present in small as well as big cities worldwide. This has become alarming due to the use of polythene bags and other solid materials which are dumped into the sewer system. The sewage lines get frequently choked leading to their blockage and overflow which results in sanitation problems and creates health hazard for citizens and labours. When manpower involved in clearing the block, it leads to fatal due to hazardous gases present in it. In this project, to overcome the issue of hiring Man power into the manhole to remove the blockage, we introduce an intelligent clearance system using IoT. This system consists of level sensor, Arduino, RF transceiver, gas sensors, relay, valve, LCD and Bluetooth. Level sensor detects the level flow in the sewage system and we can detect the block by flow of water and Gas sensor is used to detect the hazardous gas in sewage system which leads to fatal. Once the sensor crosses its threshold value it gives alert to concerned authority through mobile. Once the block is detected, the alert is received and highly concentrated liquid is given through the valve which is driven by relay to clear the block without using man power. This system has economic impact and will be useful to environment and sewage workers
