TITLE 5 PUBLIC UTILITIES AND PROPERTY

CHAPTER 1 SEWER CONNECTIONS AND CHARGES

SECTION 5-1-3 DOMESTIC AND COMMERCIAL USER CHARGES (INSIDE CITY)

   
  (A)          General: This is a user charge for a small community which follows model number one in Appendix B of the Federal Register dated 9-27-78. This treatment work is primarily flow dependent and will utilize the equivalent user concept. A sewer user charge shall be levied on all users of the sewage collection and treatment facilities, for the purpose of allocating among such users the costs of operation, maintenance, replacement and financing of this facility in approximate proportion to each user's contribution to the total wastewater load of such facilities. 
   
  (B)           Basis for User Charge: The sewer user charge shall be based on the user's contribution to the total wastewater loading of the treatment facilities in comparison to a standard, equivalent user as defined. The sewer user charge for each user shall be in accordance with the equivalent user schedule established below. The sewer user charge for a single user having more than one classification of use shall be determined by adding together the equivalent users for each classification. The user charge for special users contributing sewage of excessive flow and/or strength, for which the tabulated equivalent users below do not apply, shall be individually calculated users provided below. The monthly fee to be paid by each user shall be computed by multiplying the sewer user charge for each user by a constant monthly factor which shall be as set by the Menan City Council. The minimum sewer user charge shall be one (1) equivalent user.
   
  (C)          Definition of Equivalent User: One equivalent user shall be defined as contributing 350 gallons per day of wastewater containing not more than 0.7 pounds of 5-day Biological Oxygen Demand and 0.7 pounds of suspended solids. The equivalent user flow has been developed from population and sewer usage records which indicate an average single dwelling unit has 3.5 people contributing 100 gallons per day. Standard engineering data indicates 0.2 pounds of 5-day Biological Oxygen Demand and 0.2 pounds of suspended solids respectively per person per day. The basic equivalent user shall be subject to revision if population, water usage, sewage volume and/or other information indicates flow and/or strength is significantly different from that defined herein. Revision of the basic equivalent user criteria shall normally only be made upon the recommendation of a registered, professional engineer.
   
  (D)          Equivalent User Schedule: The number of equivalent users that shall comprise the sewer user charge for each user and/or user class shall be in accordance with the following equivalent user schedule in the absence of flow information. Assignment of equivalent users shall apply for one (1) year until the next annual user charge review. Users so indicated, or not included in this schedule, shall be considered special users and shall be evaluated separately as provided below. If and when the information indicates that the strength of sewage contributed by any of the following users is in excess in comparison with the allowable limits listed above, then a surcharge shall be levied against such users as provided below. Any of the users in the following schedule may be classified as special users if information on their contribution flow and/or strength indicates a need to do so.

  (E)           Surcharge for Excessive Strength: When any user contributes wastewater having an average biological Oxygen Demand and/or suspended solids loading in excess of the designated allowable limits hereinafter designated, a surcharge shall be levied against such user. Said surcharge shall apply to sewage strength in excess of 200 mg per liter of Biological Oxygen Demand and 200 mg per liter of Total Suspended Solids. Said surcharge is based only on operation and maintenance costs for the current year's city budget as determined in the user charge system. Said surcharge shall be levied against the user in excess of the charge provided in the user charge system schedule. The proportion of the Operating and Maintenance Costs (O & M Costs) shall be distributed as follows:
   
              Flow = 60%
              Biological Oxygen Demand = 20% x Costs of Operations and Maintenance.
              Total Suspended Solids = 20% x Costs of Operations and Maintenance.
              
  The Biological Oxygen Demand and Total Suspended Solids loading shall be determined from the tests averaged over the period made by City officials or the City Engineer. The monthly user surcharge shall be computed by use of the following equations:
   
  Biological Oxygen Demand/$Month = Total Flow/Month x Biological Oxygen Demand - 200 x 20% Equivalent Users Operations and Maintenance                   
  Tested
  200                  10, 500
   
  WHERE           : Flow is in Gallon
  : Biological Oxygen Demand tested is in ppm or mg/l
  : 200 is the allowable limit in ppm or mg/l
  : Equivalent Users Operations and Maintenance in ppm or mg/l
   
   
  Total Suspended Solids/$Month = Total Flow/Month x Total Suspended Solids - 200 x 20% x Equivalent Users Operations and Maintenance
  Tested
  200                  10,500
   
  WHERE           : Flow is in Gallon
  : Total Suspended Solids tested is in Parts Per Million or Milligram 
  Per Liter
  : 200 is in Parts Per Million or Milligram Per Liter
  : Equivalent Users Operations and Maintenance in Parts Per 
  Million or Milligram Per Liter
   
  A copy of the list of user surcharge, the characteristics of their sewage and the surcharge for each shall be kept on file at all times in the Office of the City Clerk.
   
  (F)           Special Users: If, in addition to excessive strength, a user is determined to add flow to the lagoon in excess of 10,000 gallons per month, the above formula shall be multiplied by a factor of total flow divided by 10,000 gallons per month. In order to determine the flow of this special user, the City may monitor sewage and water flow in order to determine total flow. The value of User's Monthly Charge computed in the formula above will be the same value as assigned single dwelling units. "UMC" represents the basic user's monthly charge computed as provided for above.
   
  (G)          Review and Revision of User Charges: The sewer water user charges shall, as a minimum, be revised annually and updated to reflect each user's actual contribution to the wastewater load of the sewer collection and treatment facilities. Any revision of the user charges shall be based on actual operation, maintenance, replacement and financial expenses and/or on significant changes in the total number of equivalent users, the total daily flow, the total daily Biological Oxygen Demand, and/or the total daily suspended solids. The city may install flow-measuring devices and/or collect wastewater samples at any time in any user's service line to determine actual usage as a basis for revision of the user's charge. Revisions due only to changes in expenses and user class shall be made by the City. Revisions involving user's flow, Biological Oxygen Demand and/or suspended solids shall normally only be made  by the city. Revisions involving user's flow, Biological Oxygen Demand and/or suspended solids shall normally only be made upon the recommendation of a registered, professional engineer. All changes in user charges applicable to the Ordinance shall be computed by the methods outlined herein.
   
  (H)          User Request for Change in User Charge: Any sewer user, who feels his user charge is unjust and inequitable as applied to his premises within the spirit and intent of the foregoing provisions may make written application to the City Council requesting a review of his user charge. Said written request shall, where necessary, show the actual or estimated average flow and strength of his wastewater in comparison with the values upon which the charge is based, including how the measurements or estimates were made. Any flow measurements and/or testing of wastewater shall be approved in detail by the City and/or its engineer. Review of the request by the City Council shall determine if it is substantial or not, including recommended further study of the matter for the City and/or user by a registered, professional engineer.
