A. 
Applicability of disposal charge. The wastewater disposal charge established shall apply to each lot or parcel of land, building or premises (hereinafter called premises) from which wastewater is discharged into any public sanitary sewer and to each premises for which a connection to any sewer is ordered installed, such charges to take effect upon the expiration of the time limited for the installation of the sewer connection or upon use of the connection for the disposal of wastewater, whichever occurs first.
B. 
Basis of charge. In order to ensure a proportional distribution of the costs of furnishing wastewater disposal services, several factors, including strength, volume and delivery flow rate characteristics, shall be considered in determining the appropriate wastewater disposal charge for a particular user.
C. 
Use of water meters.
(1) 
The wastewater disposal charge herein established shall be based upon the amount of water used upon the customer's premises, including water from public and private supplies, or as provided below, upon the amount of wastewater discharged to the public sewer. If any person discharging wastewater into the public sewer system procures any part or all of his water from sources other than the City Water Utility, all or part of which is discharged into the public sewers, the person shall be required to have water meters installed for the purpose of determining the volume of water obtained from these other sources. Where wastewater meters are already installed, no water meters will be required. The water meters shall be furnished by the City Water Utility and installed under its supervision, all other costs being at the expense of the user requiring the meter.
(2) 
The City Water Utility will charge for each meter rented. The rental charge will be based on the meter size by the Water Utility to compensate for the cost of furnishing, reading and servicing the meter.
(3) 
Failure to meter any water supply shall not release the customer from paying the wastewater disposal charge thereon. In such cases, the charge shall be based upon an estimate from the Control Authority of the flow for the billing period.
D. 
Exemption meters.
(1) 
If a person discharging industrial wastes into the public sewers produces evidence satisfactory to the Control Authority that significant amounts of the total annual volume of water used for all purposes does not reach the sanitary sewer, the person may be permitted to have an exemption water meter installed. The meter shall be furnished by the City Water Utility and installed under its supervision, all other costs being at the expense of the person requiring the meter, including any piping revisions required to ensure that only water not reaching the sanitary sewer is metered by the exemption meter.
(2) 
The City Water Utility will charge for each meter rented. The rental charge will be based on the meter size by the Water Utility to compensate for the cost of furnishing, reading and servicing the meter.
(3) 
The amount of exemption water metered shall be subtracted from the total amount of water used by the person and an adjusted total water usage determined based on only water reaching the sanitary sewer. This adjusted total water usage will be used to determine the applicable wastewater disposal charge.
E. 
Waste meters. Devices for metering the volume of waste discharged may be required by the Control Authority if these volumes cannot otherwise be determined by the use of water meters and exemption water meters. Metering devices for determining the volume of waste shall be purchased, installed, owned and maintained by the person. The type of meter and metering arrangement shall be approved by the Control Authority before installation and it shall be installed in accordance with approved methods. Following approval and installation, the meters may not be removed without the consent of the Control Authority. If the metering facilities fail to operate or register the flow correctly, the wastewater disposal charge shall be based upon the estimate of the Control Authority of the flow of wastewater for the billing period.
F. 
Calculation of sewer service charges.
(1) 
Category A. Category A is defined as normal or domestic strength wastewater having concentrations of biochemical oxygen demand (BOD5), total suspended solids, ammonia nitrogen (NH3-N), and phosphorus no greater than 250, 250, 25, and 10 mg/L respectively as defined under §§ 639-4. The sewer service charge for Category A wastewater is determined as follows: sewer service charge (SSC) = fixed charge (FC) + volume charge (VC).
(a) 
Fixed charge (FC) = quarterly or monthly charge which represents the user's proportionate share of those charges determined to be most equitably collected from customers based on the number of customers connected to the system. These charges include all or part of meter reading and billing costs, collection system costs, costs associated with infiltration and inflow (I/I) and certain debt service associated with excess capacity amounts.
(b) 
Volume charge (VC) = volume discharged into the domestic wastewater system times the volumetric unit charge in effect stated in dollars per 100 cubic feet ($/CCF).
(2) 
Category B.
(a) 
Category B is defined as wastewater having organic concentrations for either biochemical oxygen demand (BOD5), total suspended solids, ammonia nitrogen (NH3-N), or phosphorus greater than those established for Category A. The sewer service charge for Category B wastewater is determined as follows:
Sewer Service Charge
=
Category A Charge + High Strength Surcharge
High Strength Surcharge
=
(CBOD x XBOD5) + (CTSS x XTSS) + (CP x XP) + (CNH3-N x XNH3-N)
CBOD
=
BOD5 unit cost in dollars per pound
XBOD5
=
Pounds of BOD5 greater than Category A BOD5 wastewater
CTSS
=
TSS unit cost in dollars per pound
XTSS
=
Pounds of TSS greater than Category A TSS wastewater
CP
=
Phosphorus unit cost in dollars per pound
XP
=
Pounds of phosphorus greater than Category A phosphorus wastewater
CNH3-N
=
Ammonia nitrogen unit cost in dollars per pound
XNH3-N
=
Pounds of ammonia nitrogen greater than Category A ammonia nitrogen wastewater
(b) 
The Category A charges for fixed charge and volume charge and the Category B surcharges for BOD, TSS, ammonia nitrogen and phosphorus will be established by City Council resolution and revised from time to time in order to be adequate to pay all of the operating, maintenance, replacement and capital costs of the Utility.
(3) 
Discharge measurement. Where samples are taken often enough to produce meaningful averages, wastewater disposal charges will be determined based on the average values determined during the billing period after due allowance for values not believed to be representative. Any person may request that the Control Authority make new tests, the tests to be at the expense of the person discharging the waste and the tests to be of a minimum of 24 hours' duration, unless otherwise approved. If the Control Authority is satisfied that the test was made when the plant was operating under normal conditions, the results of these tests may be used in computing the subsequent wastewater disposal charge in the manner previously prescribed. Records of the results of the monitoring shall be kept and the results shall be reported to the Control Authority. The Wastewater Superintendent shall make the records available upon request to state, federal or any other public agencies having jurisdiction over such discharges, as allowed by law.
A. 
Purpose. It is the purpose of this section to provide for the recovery of costs for the activities necessary to administer pretreatment standards and requirements or any other local, state or federal requirements. These fees are separate from all other fees chargeable by the City. The applicable charges or fees shall be set forth as adopted by resolution of the City Council.
