        abstract = {Urban drainage and sewage systems are essential components of smart city infrastructure. However, drainage overflow, manhole blockages, and accumulation of toxic gases such as methane pose serious threats to public safety and sanitation workers. Manual inspection, which is time-consuming, inefficient, and hazardous. This paper presents an IoT-based drainage overflow and manhole monitoring system using NodeMCU (ESP8266) and Arduino Cloud. The proposed system continuously monitors water level, gas concentration, and temperature inside manholes using sensors. Sensor data is transmitted in real time to the Arduino Cloud platform through Wi-Fi, enabling remote monitoring, visualization, and alert generation. Automated alerts are triggered when sensor values exceed predefined safety thresholds, allowing authorities to take timely preventive action. The system improves public hygiene, enhances worker safety, and supports smart city development through reliable, scalable, and cost-effective wastewater management.},
