What is an Equivalent Runoff Unit (ERU)?

The Equivalent Runoff Unit, or ERU, is the base unit for the stormwater user fee, similar to the base unit for other utilities. An ERU is a measure of the amount of impervious surface on a property. One ERU is equal to 3,770 square feet of impervious area. This is the average amount of impervious surface found at the average single-family residence in Georgetown County. The charge for one ERU will be $52 per year.
