(A) Residential users. Wastewater processing fees for residential users discharging normal strength wastewater to the POTW shall be based on water consumption data for the property as measured by the water meter that is owned and maintained by the water supply company which provides water to the property or premises. Determinations of quantity of water used or quantity of flow discharged to the POTW may be accomplished by other means where such alternate means are allowed elsewhere in this chapter, or authorized by the Superintendent.
(B) Non-residential users not having effluent meters. Wastewater processing fees for non-residential users that have not been required to install suitable flow measurement devices to determine the quantity of flow discharged to the POTW shall be based on water consumption data for the property as measured by the water meter that is owned and maintained by the water supply company which provides water to the property or premises. Determinations of quantity of water used or quantity of flow discharged to the POTW may be accomplished by other means where such alternate means are allowed elsewhere in this chapter, or authorized by the Superintendent.
(C) Non-residential users having effluent meters. Wastewater processing fees for non-residential users that have been required to install suitable flow measurement devices to determine the quantity of flow discharged to the POTW shall be based on the data obtained from the flow measurement device. Such devices shall be non-resettable, totalizing devices, which have been inspected and approved by the Superintendent, or an authorized designee.
(D) Authority to determine the most appropriate data for calculations. The city shall reserve the right to calculate wastewater processing fees using water consumption data when the city believes that the data from devices measuring the quantity of flow discharged to the POTW has been falsified, tampered with, corrupted, or is otherwise unreliable. The city shall also reserve the right to calculate wastewater processing fees using data from a facility’s effluent flow measurement device; when the city believes that the data from that measuring device is more credible than the water consumption data.
(E) Authority to require flow measurement devices. The city shall reserve the authority to require the installation of meters, weirs, volumetric measuring devices, or other flow measurement devices acceptable to the city in order to facilitate accurate determinations of the quantity of wastewater discharged to the POTW. Such devices shall be installed and maintained at the user’s expense in situations such as but not limited to the following:
(1) In the event that the total water consumption for a user’s property or facilities therein contained is not measured by a water meter or other acceptable flow measurement device; or
(2) In the event that the existing influent water meter (or meters) do not accurately and reliably measure the total water consumption for the user’s property or facilities therein contained; or
(3) Where existing facility influent water meters are not of a non-resettable, totalizing type; or
(4) Where existing meters are otherwise unacceptable to the city.
(F) Petitions for billing on actual quantity discharged. A user whose wastewater processing fees assessed per § 55.103 are based upon metered water consumption data may petition the city to be billed on the actual amount of wastewater discharged to the POTW provided that the following criteria are met:
(1) The user must demonstrate to the satisfaction of the city that the metered water consumption for their property or facility contained thereon exceeds 10,000 gallons per month; and
(2) The user must further demonstrate to the satisfaction of the city that a portion of the total water consumption measured by the water meter or meters does not and cannot enter the POTW; and
(3) The user must agree to install and maintain a meter or meters acceptable to the city in such a manner as to determine the quantity of water actually entering the POTW; and
(4) The user must agree to install and maintain such meters as are acceptable to the city at the user’s own expense; and
(5) The user must submit the request along with the required supporting information and documentation to the Board of Public Works and Safety for consideration and final approval. Upon approval, the user shall be billed only for that measured quantity of water entering the POTW.
