Drainage is the system or process by which water, sewage or other liquids are drained from the place. In order to maintain the proper function of drainage, its condition should be monitored regularly.But manually it is very difficult to monitor all area where a human cannot reach. This influences the blockage of underground pipes and overflows of water cause the health problem. To mitigate all these issues here we are developed and implemented the system using wireless sensor network. It consisting of small devices used to collect data. These sensing devices are called node. The proposed system is low cost, less maintenance, long life and Web-based real time system, which update the municipal officer by text message when any manhole crosses the threshold value. This system directly impacts on the health issues of citizens and worker who cleans the underground drainage. It also avoids spreading of infection due to mosquitoes and gives clean and healthy environment as well as controls the diseases such as malaria, dengue, diarrhea, etc. The system reduces the accident caused by an exposed manhole.
