7.15.010 Customer class EDU determination.
As set forth below, the board hereby modifies three new wastewater customer classes, along with a corresponding method for billing customers for wastewater service including, if applicable, calculating EDUs.
A. Military Base Customer Class. 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 170 gallons to arrive at the number of EDUs. 170 gallons is the average amount of wastewater flow from a single-family residential customer.
B. School Customer Class. Customers in this class shall annually be assigned a fixed number of EDUs based on the annual student count reported to the state of California, and with each student assumed to be discharging two gallons of wastewater for all 365 days of the year. The calculation of the number of EDUs assigned to a school shall be determined by using the following formula:
Number of students x 2 gallons results in the average daily volume of wastewater. This result is then divided by 170 gallons to arrive at the number of EDUs.
Note: this customer class does not apply to the Murrieta service area due to billing restrictions imposed by the SRRRA plant.
C. Dedicated Lift Station Customer Class. Customers in this class have a dedicated district lift station that collects the customer’s wastewater flows and then pumps the flows to the plant. The lift station meter shall be used for billing purposes to calculate the amount of wastewater discharged in a 1,000-gallon unit of measurement. Note that this class currently applies to only two customers – Altavita Village, which owns and maintains its own wastewater conveyance system and therefore is only billed for wastewater treatment services, and the Ben Clark Training Center. (Res. 3029 § 4, 2018; Res. 2983 § 4, 2018)
7.15.020 WWRF East and WWRF West service areas.
Since the WWRF East and WWRF West service areas are interconnected, in that they both flow to the same plant, the board hereby authorizes the two service areas be combined for rate-setting purposes (see Exhibit A for a boundary map of these two service areas).

The WWRF East Service Area is represented by the shaded area east of the 215 Freeway; the WWRF West Service Area is represented by the shaded area west of the 215 Freeway.

7.15.040 California Environmental Quality Act.
The board finds that the administration, operation, maintenance and improvements of the district wastewater system, which are to be funded by the increased wastewater rates set forth herein, are necessary to maintain service within the district’s existing service areas as described herein. The board further finds that the administration, operation, maintenance and improvements of the district wastewater system, to be funded by the increased wastewater rates and charges, will not expand the district’s system. The district further finds that the adoption of the rates and charges is necessary and reasonable to fund the administration, operation, maintenance and improvements of the district’s wastewater systems. Based on these findings, the board determines that the adoption of the rates and charges established by this chapter are exempt from the requirements of the California Environmental Quality Act pursuant to Section 21080(b)(8) of the Public Resources Code and Section 15273(a) of the State CEQA Guidelines.
