Why is the Total Volume Calculated?

The idea behind the calculation is that based on the size of an impervious area (roof) and the predicted rainfall of a locality you can determine the amount of water runoff that will occur in a certain amount of time. This ensures a methodical approach and allows you to be confident you have a well designed stormwater system, that won't cause you any issues in the future.
