Sewage. Wastewater, Manholes, Drainage Monitoring, Worker Safety, and Gas Limits.
The sewage system plays an important role in big cities where millions of people live. The process of monitoring and maintaining the drainage system that are available now are making the workers to work at risk. The drainage may contain rainwater and unused water must be monitored and maintained properly. It leads to loss of human life and irregular condition of the drainage system if suppose this may not be conceder means this may lead to various skin infections. The process of unblocking and cleaning processes may lead to much human death because of the gas. This system will help to identify the gas level inside the drainage manholes so that the worker can get some idea of entering into the manholes. The worker can monitor his health and surrounding gas conditions in the LCD display. When the gas limit reaches the threshold limit or worker is in critical condition then an alert message will be sent to both the municipality office and hospital. The pump motor provides the oxygen to the worker until the help arrives.
