Rainwater Harvesting Calculator
Why let all that rainwater go to waste when it could be filling up your water tanks instead? Whether you're a sustainability enthusiast or just someone looking to cut down on water bills, our Rainwater Harvesting Calculator is here to help. Simply input your roof area and average rainfall, and voilà—you'll know exactly how much water you can collect. It's quick, easy, and could make a big difference in your water usage. Say goodbye to guesswork and hello to smarter water management!
Calculate the potential rainwater you can harvest from your roof or catchment area.
How It Works
The Rainwater Harvesting Calculator uses a simple formula to estimate how much rainwater you can collect:
Harvested Water (liters) = Roof Area (m²) × Rainfall (mm) × 0.9
Here's a breakdown of what each part means:
- Roof Area: The size of your roof or catchment area in square meters.
- Rainfall: The average rainfall in millimeters for your area.
- 0.9: This represents a 90% efficiency rate, accounting for some water loss due to factors like evaporation and roof material.
For example, if your roof area is 50 m² and the average rainfall is 100 mm, you can harvest approximately 4,500 liters of water.
Example Calculations
| Roof Area (m²) | Rainfall (mm) | Harvested Water (liters) |
|---|---|---|
| 10 | 50 | 450 |
| 20 | 75 | 1,350 |
| 30 | 100 | 2,700 |
| 40 | 150 | 5,400 |
| 50 | 200 | 9,000 |
