F. Provided, however, in the case of other businesses and establishments that have unusual character insofar as sewage is concerned, the rate shall be established in each case by the District Manager or his designee. The rate so established shall be fixed in consideration of the estimated or actual volume of flow and suspended solids (ss) and/or biological oxygen demand (BOD) content from such. eook . :¡ Page. I~ . . . G. The annual sewer service charges for all properties discharging sewage that passes through the District's sewer system, excluding schools, will be determined by applying the volume sewer charge per hundred cubic feet (HCF) for each customer classification to each parcel as determined by the water utility meter readings. The annual sewer service charges for schools shall be determined by applying the number of equivalent dwelling units (EDU) assigned per the average daily attendance of pupils at the school at the current rate set by ordinance. H. The property owner of record at the time the annual sewer service charge is billed shall be responsible for the sewer service charge associated with the metered water use occurring during the time period in which it is recorded. 18.08.040 Sewer Service Outside District Limits. When it appears to be in the best interest of the City/District and the people thereof, the District Engineer may prepare an agreement for property situated outside the District to be permitted to connect to the sewer system. The agreement may state the terms of connection, special conditions and limitations, cost for service, annexation fees, connection/capacity fees, and other conditions of sewer service. 18.08.050 Refunds. Back Charges. and Changes in Use Resulting in Different Rates. Sewer Service Charges and/or Connection/Capacity Fees. A. Increased Rates.

Only those amounts which were over-charged will be refunded, and without accrued interest. Refunds shall be issued for up to four years in arrears during which the property owner was over-charged for sewer service. 8cok #I ~ Page .---11.- . . . 18.08.060 Exceptions. The District Operations Manager or his designee shall have the power to grant exceptions and to establish policies for the granting of such exceptions from the established sewer service charges. Such exceptions shall only be granted when one or more of the following situations exist: A. Where the premises are not connected to the sewer system of the District. B. When water is supplied to premises through a separate water meter and such water is used entirely for irrigation purposes. C. Where the District has entered into a separate service agreement. 18.08.070 Adjustment of Sewer Service Charges Authority. The District Operations Manager or his designee shall have the power to adjust the annual sewer service charge when one or more of the following situations exist: A. When excessive water consumption is caused by unknown water pipe leaks and it is positively demonstrated to the satisfaction of the District that above-mentioned water consumption is not discharged into the sewer system. B. Where it can be positively demonstrated to the satisfaction of the District that the percentage of return to sewer is less than the amount calculated for that customer classification due to a substantial portion of the water used for industrial, recreational, horticultural or agricultural purposes. C. When water is supplied to premises by more than one water meter and one or more of such additional water meters does not provide water which is discharged into the sewer system. D. When ownership of the parcel changes after the period during which the water meter readings are recorded and the amount of water used during that period is above the median annual water use for that customer classification. It must be positively demonstrated by the customer that the recorded amount is not representative of their actual consumption for the type of use. 18.08.080 Calculation of Annual Sewer Service Charge A. SINGLE F AMIL Y RESIDENTIAL The annual sewer service charge for single family residential customers shall be determined by applying the sewer charge per hundred cubic feet (HCF) to the adjusted annual water usage. For customers of the San Dieguito Water District, the service charge will be based on the two lowest bi-monthly water meter readings from December through May, multiplied by three to arrive at the annual water usage in HCF. For customers of the Olivenhein Municipal Water District, the service charge will be determined by combining monthly water meter readings from December through May to produce three bi-monthly readings. The service charge will be based on the lowest two readings multiplied by three to arrive at the annual water usage. The annual water usage is adjusted by applying a percentage return to sewer to determine the adjusted oo,.""Ik' ~ jg Page. . annual water usage. The minimum and maximum charges established by ordinance will apply to all single family residential customers whose water utility meter readings fall under or over the established limits. B. MUL TI-F AMIL Y RESIDENTIAL The annual sewer service charge for multi- family residential customers shall be determined in the same manner as for single-family residential customers. For multi-family residential customers with separate parcels sharing a single water utility meter, the annual total water usage shall be divided among the number of parcels served and applied to each parcel equally. The annual sewer service charge will be based on the adjusted annual water usage for the parcel. The minimum and maximum charges established by ordinance will apply on a per unit basis to all multi-family residential customers whose water utility meter readings fall under or over the established limits. C. NON-RESIDENTIAL The annual sewer service charge for non-residential customers shall be determined by applying the sewer charge per hundred cubic feet (HCF) to the adjusted annual water usage. The annual water usage is based on the prior twelve months metered water usage from May through April for the customer and is adjusted by applying a percentage return to sewer to determine the adjusted annual water usage. A minimum charge has been established for non-residential customers. . D. When less than two full bi-monthly billing periods (four full monthly periods for customers of the Olivenhein Municipal Water District) of metered water use is available from December through May for residential customers, the median annual water use for that customer classification, as set by ordinance, shall apply. E. When less than three full bi-monthly billing periods (six full monthly periods for customers of the Olivenhein Municipal Water District) of metered water use is available for non- residential customers for the prior year, the median annual water use for that customer sub- classification, as set by ordinance, shall apply. When more than three full billing periods, but less than six full bi-monthly periods of metered water use is available for non-residential customers for the prior year, the use shall be normalized to one year. F. When a single water meter serves more than one customer classification on a parcel, the highest strength classification will be used in determining the rate per hundred cubic feet of water usage. G. When no median annual water use exists for a non-residential sub-classification, the number of equivalent dwelling units assigned to the parcel for the purpose of determining the sewer connection/capacity fees shall be used, multiplied by the median annual sewer service charge for the single family residential customer sub-classification. . H. When the non-residential sub-classification for a customer changes prior to the determination of the annual sewer service charge for the customer, the rate for the new sub- Book , ~ Page , Ie¡ . . . classification shall apply and the annual water usage for each customer sub-classification shall be used to determine the annual sewer service charge. 18.08.090 Challenge of Sewer Service Charge Determination A. Administrative Review. The property owner of record or his designee subject to the sewer service charge may apply in writing to the District Operations Manager or his designee for an exception or adjustment as hereinabove provided in Sections 18.08.060 and 18.08.070; however, no rebate of fees upon such exception shall be allowed for any fees paid one year or more preceding the filing of such application. The applicant shall complete an official Application for Review of Annual Sewer Service Charge, supplied by the District. The applicant shall furnish necessary factual data to support such application. The District Operations Manager or his designee shall review the application and approve or deny the application based on the information provided by the applicant. B. Appeal to District Manager Upon denial or conditional approval by the District Operations Manager or his designee, any applicant dissatisfied with such decision may appeal same to the District Manager. C. Appeal to District Board Upon denial or conditional approval by the District Manager, any applicant dissatisfied with such decision may appeal same to the District Board. Such appeal must be filed in writing with the Board Clerk within thirty (30) days after the notice of such decision. 18.08.100 Sub-Meters If the property owner determines that it is in their best interest, a sub- meter may be used to demonstrate to the satisfaction of the District that the percentage of return to sewer is less than the amount calculated for that customer classification. A. Readings obtained from sub-meters installed for the purpose of measuring exclusively indoor or outdoor water use in HCF may be used by the District for the purpose of calculating the annual water usage if the following conditions are met: 1. An application requesting that the water readings from a sub-meter be considered in determining the annual sewer service charge be completed by the customer prior to the installation of a new sub-meter. 2. The use of the sub-meter be pre-approved by the District Operations Manager or his designee prior to installation. 3. The sub-meter be connected to a water line exclusively used for indoor or outdoor water use. 4. The sub-meter be inspected and certified by the County Department of Agriculture, Weights, and Measures on an annual basis. ti......... ~ p.' ~O . . . 5. An annual service charge may be imposed by the respective water agency for the meter reading during which the usage is recorded. The above-mentioned charge shall be set by ordinance. B. A penalty will be imposed by the District for any sub-meter found to be tampered with, adjusted, or improperly installed to produce false readings~ ...,. , ~ ,.... . ~
