Catch the rain water, Calculation of water wastage description provide me now

When it rains, water falls onto surfaces such as roofs, sidewalks, and roads. If this water is not collected and utilized, it can become wasted water that flows into storm drains and eventually into bodies of water, which can lead to pollution and other environmental issues.

To calculate the amount of water wasted during a rain event, you can follow these steps:

Determine the area where the rain fell: Calculate the area of the surfaces where the rain fell, such as the roof or the parking lot.

Estimate the amount of rainfall: You can obtain this information from local weather reports or from rain gauges if you have them installed on your property.

Calculate the amount of water that fell: Multiply the area where the rain fell by the amount of rainfall. This will give you the total amount of water that fell on that surface.

Estimate the amount of water that was captured: If you have rain barrels, cisterns, or other collection systems in place, you can estimate the amount of water that was captured.

Subtract the amount of water captured from the total amount of water that fell: This will give you the amount of water that was wasted.

For example, let's say that it rained 1 inch (2.54 cm) in your area and the roof of your house has an area of 1,000 square feet (93 square meters). The total amount of water that fell on your roof would be:

1 inch (2.54 cm) x 1,000 square feet (93 square meters) = 623 gallons (2,356 liters) of water

If you have rain barrels that can hold 100 gallons (378.5 liters) of water, and you managed to capture 400 gallons (1,514 liters) of water, the amount of water wasted would be:

623 gallons (2,356 liters) - 400 gallons (1,514 liters) = 223 gallons (843.5 liters) of water wasted.
