That Article VII, Section 55-100 of the Code of Ordinances, City of Corpus Christi, be and the same is hereby amended as follows: (b) Effective for service received beginning with utility reading cycles on or after June 11, 1993, monthly wastewater charges to one -family residential customers shall be computed on the basis of the "winter average" or the "interim average" as set forth below: Methods of Calculating Winter Average Billing for One - Family Residential Customers. (1) Definitions. a. Winter averaging wastewater charge period - The period of water and wastewater service during the three (3) complete consecutive reading periods commencing on or after November 15 of each year. During the three (3) complete consecutive reading periods, the city shall establish monthly wastewater service charges for customers based upon their average monthly water consumption. The customer must receive wastewater service at one location during the three (3) consecutive reading periods in order to establish a "winter average" except as otherwise provided herein. MS5000.031.abf (L 965 2 b. Winter average - The monthly wastewater usage established by the City of Corpus Christi during the "winter averaging wastewater charge period". This usage is the basis for monthly billings for service received until June 1 of each year. Billings for service received on or after June 1 (Junc 11 for 1993) will reflect wastewater usage based on the previous "winter averaging wastewater charge period." c. Interim average - The monthly wastewater usage established by the city for customers who have not established a "winter average". The "interim average" shall be seven thousand (7,000) gallons per month and shall be the basis for monthly billings until a "winter average" is established as per paragraph (b)(1)b above. d. Service area - The geographic region served by the city's wastewater system. (2) Winter average criteria. a. "Winter average" charges shall apply to one - family residential customers only. b. The "winter average" shall be based on a customer's average water consumption for three (3) complete consecutive reading periods commencing with the customer's first reading period on or after November 15 of each year. c. The following method will be used to calculate a customer's "winter average". MS5000.031.abf Add the three (3) winter months' water consumption to get total water consumption. Add the number of days in the three (3) monthly reading cycles to get total use days. Divide total water consumption by total use days to get daily usage. Multiply daily usage amount by 91.25 (the number of days in a quarter of a year) to get three (3) month usage. (v) (vi) 3 Divide three (3) month usage amount by three (3) to get winter average usage. Such winter average usage shall be limited to a maximum of twenty-five thousand (25,000) gallons. Using the winter average usage, apply the applicable rates established in (3) below to calculate the "winter average",- bhp for each month until a new average is established (or rates are changed). (vii) If the City is unable to obtain a sufficient number of actual meter readings to calculate a winter average, then the City may utilize any combination of actual meter readings and estimates of actual consumption to calculate the winter average. d. New and relocating customers- adjustmcnta. (i) Customers new to the service area and who have not established a "winter average" shall be billed at the "interim average" rate. After establishing water consumption at a new address for three (3) complete consecutive reading periods, and assuming the utility account is in the name of the consuming customer residing at that address, that customer may request the calculation of a winter average based on the three months of established consumption at the new address. (ii) Customers who are relocating within the service area and who established a "winter average" at their previous address shall be billed at the "interim average" rate or their "winter average" rate at the previous address, whichever is less. (iii) Customers who are relocating within the service area and who have not MS5000.031.abf 4 established a "winter average" at their previous address shall be billed at the "interim average" rate. After establishing water consumption at a new address for three (3) complete consecutive reading periods, and assuming the utility account is in the name of the consuming customer residing at that address, that customer may request the calculation of a winter average based on the three months of established consumption at the new address. When a customer experiences a substantial increase in water or beyond thc reasonable control of the customer and if thc customer notifies thc Public Utilitica Commercial Office of thc facto surrounding thc increased usage before April 1, thc director of finance or his/her designee has the discretion to adjust thc wastewater bill. e. Adjustments to winter average or interim average. A customer's winter average usage or interim average usage may be adjusted according to city policy approved by the city manager. Such city policy shall be in writing and may be amended from time to time by the city manager or his designee. Such policy shall permit adiustments for circumstances including, but not limited to water leaks or minimal consumption during new construction. Adjustments may also be made when a customer has experienced unusually high water consumption because of extraordinary circumstances. In any case, before an adjustment will be made, the customer shall provide reliable information which enables city staff to verify the facts upon which a request for adjustment is made. Such city policy, as amended, shall be on file with the City Secretary and at the Utilities Business Office. MS5000.031.abf (3) MS5000.031.ahf 5 f.e- If water conservation measures [conditions I, II, III, or IV of Section 55-151(3) ] are in effect during "winter averaging wastewater charge period" a new "winter average" will not be calculated for that year. The previous "winter average" (plus any applicable rate change enacted by ordinance) will be in effect until such time that no water conservation condition remains in effect and a new "winter averaging wastewater charge period" is completed. The new "winter average" will be effective for service received beginning with utility reading cycles on or after the June 1 following the "winter averaging wastewater charge period". Administrative change in rates. a. "Base Revenues" shall be defined as the revenues (for one -family residential wastewater customers) proposed by the city manager to be budgeted for the forthcoming fiscal year, based on normal rainfall and not including any growth in the customer base or any anticipated rate increase. The city manager shall report his method of calculation of the base revenues to the City Council each year before implementing the adjusted rate under "c" below. b. In order to convert to the winter averaging system enacted herein, the city manager shall, based upon the winter average wastewater usage determined during the winter averaging wastewater charge period, adjust the rate applied to each customer's winter average or interim average so that the adjusted rate will produce an amount equal to the base revenues. c. The city manager shall implement the adjusted rate effective for service received beginning with utility reading cycles on or after June 1 (Juno 11 for 1993). There shall be at least one (1) full billing cycle between the effective date of any utility rate increase and the effective date of the adjusted rate initiating the winter averaging program. d. Each year after 1993, the City Manager shall perform the calculations for base revenues and winter averages described in subsections (a) and (b) of this section. Adjusted rates shall then be established for that year as provided 6 in subsection (c). SECTION 2. If for any reason any section, paragraph, subdivision, clause, phrase, word or provision of this ordinance shall be held invalid or unconstitutional by final judgement of a court of competent jurisdiction, it shall not affect any other section, paragraph, subdivision, clause, phrase, word, or provision of this ordinance, for it is the definite intent of this City Council that every section, paragraph, subdivision, clause, phrase, word, or provision hereof be given full force and effect for its purpose.

The wastewater winter averaging ordinance requires the City Manager to adjust wastewater charges for one family dwellings after each winter. When applied to the most recent actual winter average consumption, the adjusted charges will produce the same level of revenues. The annual adjustment process may cause either an upward or downward adjustment in charges. The magnitude and direction of adjustments depends primarily upon changes in actual water consumption during winter months. This year the winter average charges which determine individual customer's wastewater bills will decrease by approximately 6.7% due to increased water consumption. The average monthly water consumption by one family dwellings in the City during the past winter was 443,241,000 gallons. The previous winter's monthly consumption was 396,849,000 gallons. The number of customers increased from 64,428 to 64,808. The average consumption per customer increased by 679 gallons per month. Therefore, an adjustment will be made to the charges which determine individual customer's wastewater bills beginning with service provided June 1, so that the base revenue will be maintained. The present charge is a minimum of $9.404 for the first 2000 gallons, plus a volume charge of $1.899 for each additional thousand gallons. The adjusted charge will be a minimum of $8.811 and a volume charge of $1.780/1,000 gallons for calculating the winter average amount which will show up on wastewater bills beginning in early July. Each customer will be sent a letter approximately a week before the bill is sent explaining the new wastewater winter average charge for that customer.
