IoT Enabled Manhole Surveillance System

A sewage system is a system of pipes, pumping stations, and other equipment used to transport sewage from its sources to a location for treatment and disposal.Today, the same method is used to transfer many types of data, including power, biogas, and communication networks like fibre.Because of this, the sewage system is important for creating a healthier and cleaner community, and our initiative aims to support an intelligent drainage system.People are dealing with a lot of problems as a result of the system's poor maintenance, including toxic gas exposure, rising water levels inside the sewage system, and accidents brought on by the incorrect placement or absence of manhole lids.As a result, we have created a system to address these issues.The created system seeks to continuously monitor the sewage system.The system can track changes in harmful gas levels (methane, ammonia, CO2, CO, etc.), the level of water in sewage tunnels, and the displacement or tilting of manhole lids.All of this information is communicated with the appropriate authorities via a secure web application and telegram application.Additionally, a system for alerting people to the sewage system's critical problems is included.A solenoid valve system has been added to the hazardous gas pressure control system inside the manhole, and with the system's assistance, the gas levels inside the manhole can be regulated by releasing a tiny amount of gas in response to commands sent by telegram bot or website.
