Rainwater Collection Calculator

Calculate the potential volume of rainwater that can be collected from your roof based on roof area, average rainfall, and collection system efficiency.

Input Parameters

Calculation Results

Calculation Formula

Volume (liters) = Roof Area (sq. meters) × Average Rainfall (mm) × 1000 × (Efficiency / 100)

Where:
Volume (liters) - The total volume of rainwater collected in liters.
Roof Area (sq. meters) - The area of the roof in square meters.
Average Rainfall (mm) - The average annual rainfall in millimeters.
Efficiency (%) - The efficiency of the rainwater collection system as a percentage.

Result

0 liters

How to Use the Calculator

  1. Enter the area of your roof in square meters.
  2. Enter the average annual rainfall in your region in millimeters.
  3. Enter the efficiency of your rainwater collection system as a percentage.
  4. Click the "Calculate" button to compute the potential volume of rainwater that can be collected.
  5. Use the "Reset" button to clear all inputs and start over.

Understanding the Formula

The calculator uses the following formula to estimate the volume of rainwater that can be collected:

Volume (liters) = Roof Area (sq. meters) × Average Rainfall (mm) × 1000 × (Efficiency / 100)

This formula takes into account the area of the roof, the amount of rainfall, and the efficiency of the collection system to provide an estimate of the total volume of rainwater that can be collected.

Practical Applications

The Rainwater Collection Calculator can help you plan for rainwater harvesting by providing an estimate of the potential volume of rainwater that can be collected. This information can be used to design a rainwater harvesting system that meets your needs, whether for garden irrigation, domestic use, or other purposes.
