(A) The following schedule of rates shall apply to each user of the sewerage treatment system. This schedule includes rates for user charges and rates for debt service charges, each based on the volume of metered water consumption. There are two classes of sewer users, those classes having been established by city ordinance No. 78-8 pursuant to KRS 96.912-96.924.
(B) For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
CHARGES FOR DEBT SERVICE. Charges levied on users of the sewage treatment system to support the annual debt service obligations of the system.
EXCESSIVE STRENGTH SURCHARGES. Charges levied on users of the sewage treatment system whose contribution contains pollutants in concentrations which exceed limits specified herein for such pollutants.
SEWER SERVICE CHARGES. Charges levied on all users who discharge, cause or permit the discharge of sewage into the public sewage treatment system.
USER CHARGES. Charges levied on users of the sewage system to offset the cost of operations and maintenance of the system.
(C) (1) Phase V. The rates for each class of sewer user, based on metered water consumption, on bills mailed after July 1, 2018 are as follows:
Class I — Inside City Limits: Water Consumption — Inside City - Rates Per Month | |
Water Consumption | User Charge |
First 300 cu. ft./mo. | $26.51 (min.) |
Next 400 cu. ft./mo. | $7.98 per 100 cu. ft. |
Next 5,000 cu. ft./mo. | $7.21 per 100 cu. ft. |
Next 5,000 cu. ft./mo. | $6.45 per 100 cu. ft. |
Over 10,700 cu. ft./mo. | $5.71 per l00 cu. ft. |
Class II - Outside the City Limits: Water Consumption - Outside City - Rates Per Month | |
Water Consumption | User Charge |
First 300 cu. ft./mo. | $53.03 (min.) |
Next 400 cu. ft./mo. | $15.96 per 100 cu. ft. |
Next 5,000 cu. ft./mo. | $14.45 per 100 cu. ft. |
Next 5,000 cu. ft./mo. | $12.85 per 100 cu. ft. |
Over 10,700 cu. ft./mo. | $11.42 per l00 cu. ft. |
Wholesale Sanitation District Customers
|
Flat Rate: $8.74 per 100/cubic feet of measured wastewater flow. |
(2) Sewer rates provided in division (C)(1) of this section are based on the underlying assumption that 90% of all metered water consumption is eventually returned to the sewage treatment system. Where is can be evidenced that the proportion of metered water consumption actually returned to the treatment system by an individual customer is significantly different from 90%, service charges shall be determined on the basis of measured or estimated wastewater discharge. In this event, service charges shall be computed by applying rates shown in division (C)(1) of this section plus 11%. The city reserves the right to determine by whatever means and methods it may find practicable, the amount of water consumption and/or wastewater discharge that shall be used to compute sewer service charges.
(3) In the event discharges wastes to the sewage works having an average biochemical oxygen demand (BOD) content in excess of 225 mg/l, and/or an average suspended solids (SS) content in excess of 265 mg/l, and or an average ammonia nitrogen (NH3-N) content in excess of 25 mg/l, the user shall pay a surcharge based upon the excess strength of its wastes.
(4) If the Controlling Authority (CA) during investigative grab sampling discovers an industrial user discharging a slug of wastewater higher in strength then the allowable limits for the surcharge parameters of BOD, TSS, and NH3-N, then the following steps are to be taken:
(a) A surcharge fee of 10% of the normal surcharge fee will be assessed.
(b) The industrial user will implement composite sampling of not less than one ounce per month and not more than once per day based on direction of the Control Authority.
(c) If surcharge parameter violations are chronic as opposed to slug loading, all normal surcharge procedures and fees are to remain in effect.
(5) The following surcharge rates shall apply to each user of the sewage works that contributes excessive strength sewage.
Surcharge Rates
| |
BOD | $0.35 per pound |
SS | $0.29 per pound |
NH3-N | $1.25 per pound |
(D) Method of billing.
(1) Sewer service charge shall be billed monthly on the basis of each user’s monthly water consumption/sewage contribution and strength of discharge. The excessive strength surcharge shall be based on the following formula, with the total applied to the monthly bill of affected users:
[A(D-255) + B(E-265) + C(F-25)] .006238 x G = Surcharge Payment ($/Mo.)
Where formula components are as follows:
(a) Surcharge rate for BOD, in $/pound.
(b) Surcharge rate for SS, in $/pound.
(c) Surcharge for NH3-N, in $/pound.
(d) User’s average BOD concentration, in mg/l.
(e) User’s average SS concentration, in mg/l.
(f) User’s average NH3-N concentration, in mg/l.
(g) User’s monthly flow to sewage works, in 100 cubic feet.
(2) No reduction in sewage service charges, fees, or taxes shall be permitted because of the fact that certain wastes discharged to the sewage works contain less than 225 mg/l of BOD, 265 mg/l of SS or 25 mg/l of NH3-N.
(E) Rate review.
(1) The city shall review not less often than every two years the sewage contribution of users, the total cost of operation and maintenance of the sewage works, and user charges. User charges shall be revised as necessary to accomplish the following:
(a) Maintain the proportionate distribution of operations and maintenance costs among users of the treatment system.
(b) Generate sufficient revenues to offset costs associated with the proper operation and maintenance of the sewage system.
(2) Excessive strength surcharges shall be reviewed at the time of and in conjunction with the review of user charges. Surcharge rates shall be revised where necessary to reflect current treatment and monitoring costs.
