What is it about?

Most of the existing STPs in closed campuses of Indian scenarios such as academic institutions, industries, and residential apartments employ several pumping stations in a campus and pump motors in each station that pump sewage to STP for treatment. Manual operation of such motors would lead to sump overflows that negatively impact public health and sanitation. Therefore, an IoT-based system for monitoring and controlling sewage flow is proposed in this paper that uses water level sensors and prevents sewage overflows in pumping station sumps, resulting in the utilisation of all the collected sewage for treatment. Since each campus might have different communication networks such as GPRS, WiFi, RF, or Ethernet, the proposed system is designed to work with any network.

Why is it important?

Currently, in Indian cities, the pumps are operated without any global consideration of the capacity of the treatment plant. This causes inefficient utilisation of the infrastructure. Inefficient operation of the pumping stations reduces the efficiency of the STPs due to the non-optimum supply of sewage water. Hence, efficient control of sewage flow from pumping stations is critical to producing more volume of treated water and thus reducing water scarcity.


The advantages of the proposed IoT Based System for Sewage Overflow Prevention • Reduces the possibility of human errors affecting the operation of the sewage system. • Prevents sump overflows in the context of health hazards and water scarcity. • None of the existing systems has been implemented to suit Indian scenarios. Our proposed work has been implemented and tested successfully in an academic institution
