🌧️ Smart Rainwater Harvesting System: A Step Towards Sustainable Water Management 💧
Water is the most important commodity for existence of life. In India, the main sources of water are rainwater(monsoon) that fills the rivers with water and underground water. However, we have seen a steady decline in underground water levels across India at an alarming rate that affects the agriculture and daily water needs of the citizens. This paper suggests a smart ground water recharge system that automatically recharges the ground water after rain fall. The system uses smart IOT devices, solar panel, and a filter to filter out unwanted materials that comes along the rainwater. In this paper a fully automatic rainwater harvesting is introduced that collects rainwater and filters out dirt and unwanted materials(trash) that comes along the rain. It also senses acidic content of rain and also filters it out when needed. Later on the filtered water can be directly recharged in ground, or it can also be collected in artificial pools for irrigation purpose. Polluted water can be very harmful for our environment and food cycle [14].
Water scarcity is a pressing issue, and efficient water management is the need of the hour! 🌍 That’s why I, along with my research team, developed a Smart Rainwater Harvesting System, which was recently presented at a prestigious conference. 🎤📜 This project leverages cutting-edge IoT and AI-based technologies to optimize water conservation and usage. Let's dive into the technicalities! 🚀
🌱 The Motivation Behind This Research
Traditional rainwater harvesting systems often lack real-time monitoring, predictive analysis, and automated distribution mechanisms. Our smart system aims to:
✅ Maximize water collection efficiency 📊

- 🌡️ Temperature & humidity sensors for climate data analysis
- ⚡ pH & TDS sensors to ensure water quality
2️⃣ AI-Driven Prediction & Optimization 🧠
Using Machine Learning algorithms, the system predicts:
- Expected rainfall based on historical data 📅
- Optimal storage strategies to avoid overflow 🌊
- Water usage patterns for efficient distribution 🚰
3️⃣ Automated Water Distribution 🚿
Our system uses actuators and smart valves to autonomously distribute collected rainwater based on:
✅ Soil moisture levels (for irrigation) 🌾
✅ Household water needs 🏡
✅ Groundwater recharge requirements 🌎
4️⃣ Cloud-Based Monitoring & Control ☁️
Users can monitor and control the system remotely via a web dashboard or mobile app. 📱 This provides:
- Real-time water level alerts 🚨
- Historical data trends 📈
- Customizable water usage plans 🏗️
🛠️ NodeMCU-Based IoT Implementation
Our system is built using the NodeMCU ESP8266, which connects various sensors and actuators to the cloud for real-time monitoring and automation.
📌 Sample NodeMCU Code for Water Level Monitoring
#include <ESP8266WiFi.h>
#include <FirebaseESP8266.h>
#define TRIG D1
#define ECHO D2
#define WIFI_SSID "Your_WiFi_Name"
#define WIFI_PASSWORD "Your_WiFi_Password"
#define FIREBASE_HOST "your-project.firebaseio.com"
#define FIREBASE_AUTH "your-firebase-auth-key"
FirebaseData firebaseData;
void setup() {
Serial.begin(115200);
pinMode(TRIG, OUTPUT);
pinMode(ECHO, INPUT);
WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
}
void loop() {
digitalWrite(TRIG, LOW);
delayMicroseconds(2);
digitalWrite(TRIG, HIGH);
delayMicroseconds(10);
digitalWrite(TRIG, LOW);
long duration = pulseIn(ECHO, HIGH);
float distance = duration * 0.034 / 2;
Serial.print("Water Level: ");
Serial.println(distance);
Firebase.setFloat(firebaseData, "water_level", distance);
delay(5000);
}
