How many gallons of water are in my yard after it rains?

By  | 

Have you ever wondered how much water falls onto your yard during a rainstorm? Since every property and rain event is different, we need to establish some guidelines.

Using a 1-inch rainstorm as an example, we took two properties, a home and a shopping mall, and compared just how much water falls over those spaces during a storm.

Next, we upped the rainfall to 4 inches. Wait until you see how many Olympic size swimming pools it will fill.
