Traditional sewer cleaning methods include manual labour, hydraulic flushing, and chemical cleaners. Instead, this sewer drain shield system, combining ultrasonic sensors, GSM modules, nets, and PVC pipes, reduces debris entering drainage systems, thus ensuring cleaner, more efficient operations.
This solution is low-maintenance, labour-saving, and supports sustainable waste management. It aligns with the Central government’s Clean India initiative, integrating smart waste management to protect water bodies. The bill of materials is detailed in the table on previous page.
Circuit and working
Fig. 1 shows the circuit diagram of the proposed drain shield for smart cities. It is built around an Arduino Uno board (MOD1), GSM module SIM800L (MOD2), an ultrasonic sensor module (S1), and a few other components.
