Living in an environment that is clean and healthy is a right for everyone. Industrialization and development have made life easier for men, but it has also created many dangers and pollutants. Most cities have adopted an underground sewage system, and it is essential that this system functions properly to maintain the cleanliness, safety and health of the city. Underground sanitation workers face various risks, such as toxic gas explosions and sudden changes in health due to changes in the underground environment. Many underground sanitation workers die annually because of the release of toxic gases and the lack of available facilities. Leaks and bursts are inevitable and can lead to the death of sanitation workers if they are not noticed for a long time. The goal of the proposed system is to improve the safety and effectiveness of sewage treatment by early detection and warning of hazardous gases like methane, hydrogen sulphide, etc. which are a major threat to human health and environment. The system uses WSNs and strategically deploys sensor nodes along the sewage line for continuous monitoring of gas concentrations. The sensor nodes have gas sensors that detect specific gases, microcontrollers to process the data, and wireless communication module to send real-time information to the central control unit (CCU). The CCU, using smart Internet of Things (IoT) technologies and algorithms, collects and analyzes incoming data to detect potential gas leaks or anomalies. In addition, the system includes intelligent decision-making capabilities that trigger timely notifications and alerts to relevant stakeholders, allowing for immediate response actions to reduce risks and avoid potential hazards. The integration of IoT allows for remote monitoring and control functions, allowing for proactive maintenance and optimization of the sewage infrastructure.
