Conventional drainage systems often face problems such as slow construction, inconsistent quality, and blockage caused by plastic waste, leaves, and silt. This project proposes a Smart Precast Drainage System with IoT-Based Monitoring and Automatic Blockage Management to improve drainage performance and provide early warnings of blockage. The proposed system uses precast M30 concrete U-shaped drain units, inspection chambers, and cover slabs. Three ultrasonic level sensors, a backup float switch, and a rain gauge are connected to ESP32-based controllers to monitor water levels and rainfall. A rule-based method compares readings from different locations to identify possible partial blockage, severe blockage, heavy-rain overload, downstream backwater, and sensor faults. A motor-driven stainless-steel debris basket is proposed to remove coarse waste, while a passive emergency bypass provides additional relief when the main drainage path is obstructed. The report also presents hydraulic calculations, component selection, installation procedures, and an illustrative cost comparison for a hypothetical 250-metre campus roadside drain. The estimated capital cost of the smart precast system is ₹19,34,405, compared with ₹17,71,000 for conventional precast drainage. The concept may be useful at locations where flooding risks are high. However, the proposed system requires prototype testing and field validation before practical implementation.
