The City of Ammon is currently using a system that is based on Equivalent Residential Units (ERU’s).  These ERU’s are calculated on the average amount of wastewater produced per residential connection in the City, which has been determined to be 320 gallons per day (peak usage).  Please note that the amount charged per ERU is not changing because of the new method, only how many ERU’s are assigned to individual commercial and industrial uses.

This system is in place, and each residential connection will be charged for one (1) ERU.  Since commercial and industrial connections differ from residential connections, the number of ERU’s allocated for these accounts will be based on the type of business/institution and tied to a chart adopted by the Eastern Idaho Regional Sewer District (EIRSD).  This chart will also determine the amount of sewer connections that are due upon connection to the system.

Your input will ensure that the ERU’s assigned to your connection are accurate.  If your input is not received, ERU’s will be assigned based on assumptions using the best available information.  If you cannot find a type of business that you feel represents your operation, please call and talk with the City Engineer (612-4028) to discuss.  Marking the entire survey with negative answers will just slow the process down.
