Design and development of Sewage Drain Monitoring and alert system using IoT and LoRa Technology

Abstract: Urban sewage systems frequently face issues such as blockage and overflow, resulting in unhygienic conditions, health hazards, and damage to public infrastructure. Manual inspection of sewage drains is unsafe, time- consuming, and inefficient. To address these challenges, this project focuses on the design and development of a sewage drain monitoring and alert system using IoT and LoRa technology. The system continuously monitors sewage water levels using sensors and detects abnormal conditions at an early stage.
The sensed data is processed by a microcontroller and transmitted over long distances using LoRa communication, which offers low power consumption and wide coverage. A LoRa gateway forwards the data to a cloud platform for real-time monitoring and alert generation. When overflow or blockage is detected, instant notifications are sent to concerned authorities. The proposed system is cost-effective, reliable, and scalable, making it suitable for smart city sewage management and public health improvement.
