As set forth below, the board hereby modifies the billing method for wastewater service for military base customers. This customer class currently applies to only one customer, the Air Force's 452nd Air Mobility Wing located at the March Air Reserve Base. Customers in this class shall be annually assigned a fixed number of EDUs for their property based on the estimated number of weekday, weekend (day use) and weekend (day and overnight use) personnel provided by the military base. Each weekday person is assigned 25 gallons of wastewater per day, each weekend (day use) person is assigned 25 gallons of wastewater per day, and each weekend (day and overnight use) person is assigned 60 gallons of wastewater per day. The gallon amounts reflect that a nonresidential customer's flows generally peak on the wastewater system compared with a single-family residential home. In other words, nonresidential flows generally occur during a shorter period of time during a typical day compared with a residential customer, and often has little to no flow on weekends. The calculation of the number of EDUs assigned to a military base property shall be determined by using the following formula:
(Weekday personnel count x 52 weeks x 5 days per week x 25 gallons) + (Weekend day use personnel count x 12 weekends x 2 days per weekend x 25 gallons) + (Weekend day and overnight use personnel count x 12 weekends x 2 days per weekend x 60 gallons) divided by 365 results in the average daily volume of wastewater. This result is then divided by 180 gallons to arrive at the number of EDUs. 180 gallons is the average amount of wastewater flow from a single-family residential customer per Ordinance 393. |
