(a) The monthly sewer service charge for each user shall be calculated by the EDU method or the volume method.
(1) For areas where water usage is not metered, the EDU method is used to determine the applicable charges.
(2) The monthly sewer service charge for each unmetered user shall be calculated by multiplying the sum of the currently adopted operation, maintenance and replacement charge (OM&Rmonth) and the debt service charge (DSCmonth), determined under Section 1043.25, by the number of EDU's assigned to the user in accordance with the user categories and EDU criteria. (See Appendix B.)
For unmetered service areas, the monthly sewer service charge is determined by the following formula: Monthly sewer service charge = SUM x EDU
Where:
• SUM = Sum of all operation, maintenance and replacement charges and debt service charges on a monthly basis.
• EDU = Total number of equivalent dwelling units assigned to the user.
(b) If water usage in a particular area is metered, the monthly sewer service charge shall be determined by multiplying the sum of the currently adopted operation, maintenance and replacement charge rate (OM&Rrate) and the debt service charge rate (DSCrate), determined under Section 1043.25, by the monthly water usage, based on meter readings for the past month and current month.
(1) A specific rate is multiplied by each increment of 1,000 gallons of water usage in a month. Minimum charges based on meter size are also determined when metering is available.
(2) For metered service areas, the monthly sewer service charge is determined by the following formula: Monthly sewer service charge = SUMrates x Total water usage in gallons
1,000 gal.
Where:
• SUM = Sum of operation, maintenance and replacement charges, and debt rates
• Total water usage in gallons = service charge rates, per 1,000 gallons.
(c) The annual industrial wastewater surveillance charge shall be two hundred dollars ($200.00). As stated in Section 1043.26(f) hereof, this charge may be reduced if satisfactory proof that industrial wastewater is not being discharged is obtained.
