## How to Use the “Water Catchment Calculator”

The Water Catchment Calculator is a useful tool for homeowners and builders to estimate the amount of water that can be collected from a roof based on its area and the average annual rainfall in the area. The calculator is significant because it helps to conserve water and reduce the demand for municipal water supplies, especially during times of drought.

The primary applications of the Water Catchment Calculator are for estimating the water supply for gardening, irrigation, and other outdoor uses.

## Instructions for Utilizing the Calculator:

To utilize the Water Catchment Calculator, follow these instructions:

### Input Fields

The calculator requires two input fields:

- Roof Area: This is the size of the roof that will be used to collect rainwater. It is measured in square meters.
- Average Annual Rainfall: This is the amount of rainfall in millimeters that occurs in the area annually.

### Output Fields

The Water Catchment Calculator provides three output fields:

- Roof Area: This is the input value for the roof area.
- Average Annual Rainfall: This is the input value for the average annual rainfall.
- Total Water Catchment: This is the estimated amount of water that can be collected from the roof based on the input values. The output value is in cubic meters.

## “Water Catchment Calculator” Formula:

The formula for the Water Catchment Calculator is as follows: Water Catchment = Roof Area * Average Annual Rainfall * 0.001

## Illustrative Example:

Suppose a homeowner wants to estimate the amount of water that can be collected from their 100 square meter roof in an area that receives an average annual rainfall of 500 millimeters. To use the Water Catchment Calculator, they would input 100 for the roof area and 500 for the average annual rainfall. The calculator would estimate that the total water catchment is 50 cubic meters.

## Illustrative Table Example:

Roof Area (sq m) | Average Annual Rainfall (mm) | Total Water Catchment (m3) |

100 | 500 | 50 |

200 | 600 | 120 |

300 | 400 | 120 |

In conclusion, the Water Catchment Calculator is a simple but useful tool for estimating the amount of water that can be collected from a roof based on its area and the average annual rainfall in the area. By utilizing the calculator, homeowners and builders can help to conserve water and reduce the demand for municipal water supplies.
