The underground drainage system is an important component of urban infrastructure. It is consider being citys lifeline. Most management on underground drainage is manual therefore it is not efficient to have clean and working underground system also in such big cities. It is difficult for the government personnel to locate the exact manhole which is facing the. Increase urbanization has caused problem with increased flash flooded after sudden rain. All successful civilization throughout the history focused on developing efficient drainage system. Diverting both waste water away from dirking and rain water towards crops in agriculture use. If the drainage system is not properly managed then pure water gets contaminated with drainage with drainage water and infection and disease may get spread. The drainage gets blocked during rainy season and it will create the problem to routine life like traffic may get jammed environment will become dirty and totality it will upset the public. In ma
ny case blocked drains can causes sewage and water to back up and potentially come up onto your property. Therefore, it is essential to develop a system which can handle underground drainage without human intervention. Underground drainage involves sewerage system, gas pipeline network, water pipeline, and manhole. Today drainage system is not HIGH-TECH. so whenever there is blockage it is difficult to figure out the exact location of the blockage. Also early alerts of the blockage are not received. Hence detection and repairing of the blockage become time consuming. Due to such failure of drainage line people face a lot of problem. So we have invented IoT base automated drainage system with blockage clearance. It main proposes is to detect the location, and the system governing the flow of sewage from the pipe and also use of flow sensor to detect the variation in the flow, get the prior alerts of blockage and locates them using IOT, trace location using GPS and sends SMS through GSM.
