How do you calculate watershed runoff?
Measure the length and width of the site for which you want to calculate surface runoff. Note the length and width in feet. Calculate the area of the site in square feet by multiplying the length times the width. Look up the average rainfall per year for your proposed site. Convert this data from inches to feet by dividing it by 12.
Why is storm water runoff a problem?
Stormwater runoff is one of the largest single contributor of pollutants to our water systems. Water that travels along solid surfaces pick up pollutants such as oil, fertilizers, and pesticides and carry them into streams and other inlets. As urban areas grow so does the amount of impervious surface.
How can you prevent stormwater pollution?
This helps prevent stormwater from reaching waterways and reduces the potential for pollution. There are several environmental benefits associated with rain barrels.
