Smart Water Purification and Quality Monitoring System for Rural and Mining-Affected Areas.
“Rural and mining areas in Jharkhand have unsafe drinking water polluted by heavy minerals, dirt, and germs, causing serious health issues. We need to build an affordable, smart water filtration device that also continuously checks water quality and warns people if it becomes unsafe to drink.”
Deconstructed Problem Blueprint
WHAT TO BUILD?
A smart hardware-software integrated system comprising a portable multi-stage water purification unit embedded with IoT sensors (pH, turbidity, TDS, temperature) and connected to a cloud-based dashboard and local alert mechanism.
WHO IS IT FOR?
Primary beneficiaries are rural citizens and mining-affected communities in Jharkhand. Operators are local community members, panchayat workers, and district water sanitation departments.
WHY DOES IT EXIST?
Existing water sources suffer from heavy mining runoff, industrial pollutants, and seasonal microbial contamination. Lack of localized, real-time testing infrastructure delays corrective action, forcing communities to consume hazardous water.
INPUT → PROCESS → OUTPUT ARCHITECTURE PIPELINE
Analog and digital sensor readings (pH, turbidity, TDS, temperature), flow rate data, power status, and manual configuration inputs.
Microcontroller (ESP32/Arduino) processing sensor data against WHO/BIS drinking water standards, edge anomaly detection, multi-stage filtration control (auto-backwash/shutoff valves), and payload encryption via MQTT/HTTP to the cloud.
Real-time web/mobile dashboard with water health status, automated SMS/buzzer alerts for unsafe parameters, health safety scores, and automated relay triggers to stop water supply when contamination spikes.
CONSTRAINTS
- Must operate reliably in remote areas with erratic power supply (needs solar power integration or battery backup).
- Low-bandwidth or intermittent cellular connectivity requiring local edge buffering (MQTT local broker/SD card logging).
- Cost-sensitive deployment for rural panchayats and low-income mining settlements.
- Robust sensor calibration to counter bio-fouling and mineral scaling from hard/mining water.
JURY METRICS
- Sensor accuracy and drift rate compared to standard laboratory instruments.
- Purification efficiency (% reduction in turbidity, TDS, and pathogen load).
- System power efficiency and off-grid run-time.
- Alert latency (time taken from unsafe sensor reading to dashboard/SMS notification).
- Cost per unit and simplicity of maintenance for local users.
CORE BOTTLENECK
Sensor bio-fouling and rapid calibration loss due to heavy mineral or acidic concentrations typical of mining-affected water sources.
Why You Should Choose This PS (Pros)
- Extremely high social impact addressing a critical public health crisis in Jharkhand.
- Clear, tangible hardware-plus-software prototype scope ideal for hardware category judging.
- Direct alignment with Jal Jeevan Mission and clean tech national priorities.
Challenges & Risks to Watch (Cons)
- Hardware handling during the offline hackathon finale carries physical transportation and electrical failure risks.
- Sourcing specialized water testing sensors and replicating mining-like contaminated water in a lab environment is challenging.

Access to safe drinking water remains a significant challenge in many rural and mining-affected regions of Jharkhand. Groundwater and surface water sources are often contaminated by suspended particles, excessive minerals, microbial impurities, and mining-related pollutants, making them unsafe for consumption. Additionally, the lack of real-time water quality monitoring makes it difficult for communities to assess water safety and take timely corrective actions.
There is a need for an affordable and intelligent solution that can both monitor water quality and purify, contaminated water. A smart water purification and quality monitoring system can help ensure access to safe drinking water, improve public health, and support sustainable water management in underserved communities.
The proposed solution is a smart water purification and quality monitoring system designed to provide safe drinking water in rural and mining-affected areas. The system continuously monitors key water quality parameters such as pH, turbidity, TDS, and temperature while utilizing a multi-stage purification process to remove impurities, harmful contaminants, and pathogens. Integrated with IoT and real-time monitoring capabilities, the system provides water quality insights,generates alerts for unsafe water conditions, and ensures the delivery of clean and safe drinking water. The solution aims to improve public health, enhance water accessibility, and support sustainable water resource management in underserved communities.
Develop a smart, cost-effective, and portable water purification system capable of monitoring and improving water quality in real time. The system should measure key parameters such as pH,turbidity, TDS, and temperature, while employing appropriate filtration and purification technologies to remove contaminants and make water safe for drinking.
The solution should provide real-time water quality information, generate alerts for unsafe conditions,and ensure the delivery of clean drinking water for rural and mining-affected communities. It should be easy to deploy, energy-efficient and suitable for operation in remote areas with limited infrastructure.
