SMART DRAINAGE FILTER SYSTEM

The Smart Drainage Filter System addresses the growing challenge of urban waterlogging and drain blockages in Indian cities. Designed as a modular, sensor-based system, it detects waste build-up in real time and alerts municipal teams before flooding or stagnation occurs. The goal was to create an affordable, low-maintenance solution that improves sanitation, efficiency, and urban resilience.

Problem & Insight

Target Users

Civic Cleaning Departments

Core stakeholders responsible for drain maintenance, waste removal, and public sanitation.

The system helps them identify clogged drains proactively and reduce manual inspections.

Urban Maintenance Teams

On-ground workers managing the physical upkeep of urban spaces.

Real-time alerts allow them to respond faster and clean only when necessary, improving productivity.

Urban Planners and Policy Teams

Professionals designing and optimizing city infrastructure layouts.

Data from the system offers valuable insights into waste patterns and drainage issues, helping in better future planning.

Urban drains often clog due to unmanaged solid waste and lack of real-time monitoring. Manual inspections are inefficient, leading to health hazards, mosquito breeding, and waterlogging during rains. We observed that most systems fail not due to design, but due to lack of data and proactive cleaning.

Proposed Solution

The Smart Drainage unit combines a three-layer modular mesh filter with an IoT-based sensor system.
Waste is trapped in stages , solids, silt, and debris , while water flows smoothly. An ultrasonic sensor continuously monitors the waste bag fill level and sends alerts via ESP32 when cleaning is needed. The modular drawer design allows easy removal, cleaning, and reinstallation.


Key Advantage: Built-in Overflow Prevention

Even when the bag is full, angled meshes ensure water doesn’t stagnate.

Continuous drainage is maintained.

Waste slides down, doesn’t block mesh.

Prevents flooding even with cleaning delays.

We followed an iterative prototyping process, beginning with quick sketches and structural explorations. Since this was an early-stage concept, we built a small-scale cardboard model to visualize how the drainage insert would sit inside an urban drain and how sensors could be placed without blocking water flow.

While this wasn’t a fully functional test model, it helped us understand feasibility, space constraints, and the system’s overall working. The prototype acted as a proof of concept, showing how a low-cost setup could eventually be developed into a flood-responsive drainage system.

The Smart Drainage project made me realize that real innovation is not just about creating new systems, but about designing ones that can sustain themselves. It taught me that cities don’t fail because systems are built wrong, but because they aren’t designed to communicate when they need help. By integrating sensors that detect waste build-up and alert maintenance teams, I understood how technology can become an active participant in public care. This project helped me see that smart design isn’t only about automation ,it’s about responsibility, empathy, and creating systems that quietly make life better for the people who depend on them.

Creating of the Prototype

After planning the overall structure and working mechanism, my teammate and I began building the physical prototype.


We first sourced all the necessary materials and then moved into the fabrication phase. Since it was our first experience working hands-on in the wood workshop, we faced several challenges , but each obstacle taught us valuable lessons about precision, material handling, and teamwork.


Once the structure was complete, we integrated the circuit system and successfully uploaded the code, bringing the prototype to life.
