To estimate rainwater harvesting, multiply the roof area by rainfall, then adjust for runoff and conversion factors.
The Rainwater Harvesting Calculator simplifies the process of determining how much rainwater you can collect from your roof or catchment area. This tool is invaluable for sustainable water management, estimating storage needs, or planning irrigation systems.
Formula
RWH = (L ∗ W ∗ ARF) / 12 ∗ 7.48052
| Variable | Definition |
|---|---|
| RWH | Rainwater Harvesting (gallons) |
| L | Roof Length (feet) |
| W | Roof Width (feet) |
| ARF | Annual Rainfall (inches) |
Solved Calculations
Example 1
A roof measures 40 feet by 30 feet, and the area receives 50 inches of annual rainfall.
| Variable | Value |
|---|---|
| Roof Length (L) | 40 feet |
| Roof Width (W) | 30 feet |
| Annual Rainfall (ARF) | 50 inches |
| Rainwater Collected (RWH) | 3,117 gallons |
Example 2
A roof measures 60 feet by 25 feet in an area with 40 inches of annual rainfall.
| Variable | Value |
|---|---|
| Roof Length (L) | 60 feet |
| Roof Width (W) | 25 feet |
| Annual Rainfall (ARF) | 40 inches |
| Rainwater Collected (RWH) | 3,745 gallons |
What is Rainwater Harvesting Calculator?
The Rainwater Harvesting Calculator is a practical tool designed to estimate the amount of rainwater that can be collected and stored from a specific catchment area, like a roof.
It aids in determining the optimal size for storage tanks, assessing rainwater harvesting potential, and planning efficient water usage.
By using inputs such as rainfall in liters per square meter, catchment area, and tank capacity, this calculator provides detailed calculations. For instance, you can determine how much rainwater a roof can collect during a specific rainfall event.
Addedly, it also supports sustainability by guiding users on rainwater harvesting tank size, runoff calculations, and roof water collection systems.
Whether you’re planning a rainwater harvesting system for a residential property or evaluating stormwater management for a commercial setup, this tool simplifies the process.
With features like integration with rainfall calculators by zip code, it is highly adaptable to various locations and climates.
Final Words:
All in all, the Rainwater Harvesting Calculator is a reliable solution for estimating water collection potential and designing efficient storage systems. It encourages sustainable practices by making rainwater harvesting more accessible and effective.
