CASE STUDY ARCHITECTURE

Water ATM System

Solar-powered clean drinking water filtration and telemetry kiosks

Water ATM System

Executive Summary

The Water ATM program installs community-managed water purification systems equipped with smart card payment terminals and IoT purity sensors. The system monitors water quality (TDS, pH, turbidity) in real-time and dispenses clean, affordable drinking water to cardholders.

Problem Statement

Contaminated groundwater causes severe waterborne diseases in villages, while standard purification systems are expensive to run and lack accountability.


Proposed Solution

Install robust water purification systems powered by solar energy, featuring RFID cards for automated water dispensing and online quality tracking.


Project Objectives

  • check_circle Deploy solar-powered filtration units
  • check_circle Issue RFID water cards
  • check_circle Track water purity metrics in real-time
  • check_circle Reduce waterborne diseases by 80%.

Technology Integration & Infrastructure

Reverse Osmosis + UV filtration systems, RFID card readers, TDS sensor modules, ESP32 GPRS telemetry boards.


Implementation Methodology

1. Ground water quality analysis; 2. Installation of multi-stage filtration units and solar panels; 3. Distribution of family RFID cards; 4. Launching real-time TDS dashboard monitoring.


Expected Outcomes

Continuous access to safe drinking water, reduction in waterborne illnesses, and a self-sustaining local operational model.


Impact & Measurable Results

Five systems operational in Nagpur region, supplying over 10,000 liters of safe drinking water daily to 500+ families.


Frequently Asked Questions

How do villagers buy water?

Families purchase preloaded RFID cards locally. Swiping the card at the ATM dispenses the selected quantity of water immediately.

How is the water quality verified?

Sensors inside the filtration tank measure TDS and pH constantly. If thresholds are breached, the ATM shuts down automatically and alerts the tech team.
