<br /> <br />Sec. 78-187. Determination of billable flow, loading and user charge. <br />(a) Basis. Each user shall pay operation, maintenance and replacement costs in proportion to the user's <br />proportionate contribution of wastewater flows and loadings to the treatment plant, with the minimum rate <br />for loadings of BOD and TSS being the rate established for a concentration of 200 milligrams per liter BOD <br />and 250 milligrams per liter TSS (i.e., normal domestic strength wastewater). Those industrial users <br />discharging segregated normal domestic strength wastewater only can be classified as commercial users for <br />the purpose of rate determination. <br />(b) User charges for normal domestic strength users. <br />(1) Calculation of billable flows and loadings. The charges assessed domestic users and those of other <br />classes connected to the city's water utility and discharging normal domestic strength wastewater shall <br />be established proportionately according to billable wastewater volume. Billable wastewater volume <br />shall be calculated as follows: <br />a. Measurement of wastewater volume for domestic users. <br />1. Domestic users connected to city water utility. Except as provided for in this division, <br />billable wastewater volume for residential users shall be calculated on the basis of metered <br />water usage. Metered water usage shall be determined by calculating a monthly average <br />based on water consumption for the months of November, December, January, February <br />and March. Usage in excess of the minimum rate will be billed on a unit cost of 1,000 <br />gallons per month. <br />2. Domestic users not connected to city water utility. The charges assessed to residential users <br />who are not connected to the city's water utility shall be established as a flat rate per <br />month based on the average water use of metered residential users in the community. The <br />city reserves the right to require residential users to install water meters for the purpose of <br />determining billable wastewater volume. <br />b. Measurement of wastewater volume for nondomestic users. The charges assessed nondomestic <br />users discharging normal domestic strength wastewater shall be established proportionately <br />according to billable wastewater volume. Billable wastewater volume shall be calculated as <br />follows: The billable wastewater volume of nondomestic users may be determined in the same <br />manner as for residential users connected to the city's water utility, except that if the city <br />determines that there are significant seasonal variations in the metered water usage of <br />nonresidential users resulting in a proportionate increase or decrease in wastewater volume, <br />then billable wastewater volume shall be calculated on the basis of monthly metered water <br />usage recorded throughout the year, or calculated on the basis of wastewater flow meters. The <br />city may, at its discretion, require nondomestic users to install, at the user's expense, a water <br />meter, or such additional water meters or wastewater flow meters as may be necessary to <br />determine billable wastewater volume. <br />c. Determination of loadings for normal domestic strength users. The billable amounts of BOD and <br />TSS will be calculated from the volume of metered water usage, as determined pursuant to this <br />section, where the billable quantities will be those attributable to wastewater at a concentration <br />of 200 milligrams per liter BOD and 250 milligrams per liter TSS (i.e., normal domestic strength <br />wastewater). <br />d. Determination of loadings for nondomestic strength users. The city may, at its discretion, require <br />nondomestic users to install a sewage monitoring facility. Each industrial user required by the city <br />to install and maintain sewage monitoring facilities shall submit to the city a monthly report of <br />daily flow and BOD on a form approved by the city. This report shall be used for billing purposes <br /> <br /> Created: 2023-03-07 12:39:08 \[EST\] <br />(Supp. No. 57) <br /> <br />Page 1 of 2 <br />
