The City Council o: Dnticello hereby ordains that I following
ordinance pertaining to sewer user charges be adopted:
CHAPTER
USER CHARGES
Section
7-3-1: Purpose
7-2-3: Computation of User Charges
7-3-3: Billing and Enforcement Procedures
7-3-4: Inspection and Control
7-3-1: PURPOSE
(A) For the purpose of providing monies necessary for the maintenance, and
operation of the disposal system of the City, including payment of principal
and interest due or accuring on bonds and other obligations issued or incurred
to finance such maintenance, and operation, there is hereby charged a "user
charge" to be collected by the City with respect to each lot, parcel of land,
building or premises, having any connection direct or indirect with the dis-
posal system of the City or otherwise discharging sewage, industrial waste,
water, or other waste directly into the city disposal system. The "user
charge" is to be paid periodically commencing with connection and continuing
(unless for good cause, waived or excused) for as long as the premises remain
connected.
7-3-2: COMPUTATION OF USER CHARGES
(A) User charges for sewer use shall be determined by the following method.
1. Establish the number of unit connections for each of the five (5)
following user classes:
a. Domestic (Residential) - single and multiple family dwellings.
b. Commercial - Businesses with less than 25,000 gal/day equivalent
sewage.
c. Industrial - Business as with greater or equal to 25,000 gal/day
equivalent sewage.
d. Institutional - Schools, churches, hospitals, nursing homes,
clinics, etc.
e. Governmental - City Hall, maintenance buildings, etc.
2. Based upon the last four quarter average recordings and testing at
the treatment plant, establish average daily total five day biological
oxygen demand (BOI� (TOT) , lbs/day) , and total suspended solids (SS
(TOT) , lbs/day) .

3. Establish the total average flow per day by water meter readings
for industrial, commercial, inst]-tutional, and governmental users
for the last four quarters. Establish the average flow per day for
the domestic users for the winter quarter.
Q(I) Industrial gallons/day
Q(C) Commercial gallons/day
Q(T) Institutional gallons/day
Q(G) Governmental gallons/day
Q(D) Domestic gallons da
Q(TOT) Q(I) + Q(C) t Q(T) + Q(G) t Q(D)
4. Establish industrial average daily BODS (I) loadings by monitoring
discharges for the last four quarters. Compute BODS loadings for do-
mestic, commercial, institutional, and governmental user classes by
subtracting the industrial load from the total BODS (TOT) levels
established at the treatment facility.
5. Establish average daily BODr, loadings for remaining user classes by
a percentage of measurable flow.
6. Establish industrial average daily SS(1) loading by monitoring dis-
charges for the last four quarters. Compute SS loadings for domestic,
commercial, institutional, and governmental user classes by subtracting
the industrial loading from the -L-otal SS (TOT) level established at the
treatment facility.
7. Establish SS loading for the remaining user classes by a percentage of
measurable flow.
8. Establish total operation, maintenance, and replacement costs for the
treatment facility and for the collection system for the year. The OMR
costs include all costs for labor, supervision, utilities, chemicals,
supplies, repairs, replacement and other maintenance related items.
9. Proportion the OMR costs as a function of percentage of Q, BODS and SS.

10. Establish annual unit charge rates for Q, BODS and SS based on totals
established in Steps 2 and 3.
Annual Unit Charge Rates:

- 2 -
11. Establish total OMR costs attributable to each user class by using
the annual unit charge rates established in step #10 and the quantities
previously established for each user class in terms of Q, BODS and SS.
12. Establish quarterly sewer user charge rates (UCR). The rate equals
the attributable OMR cost for the user class divided by the metered
water usage for the user class. The unit rate for domestic, commercial,
institutional, and governmental classes will be the same.
13. Establish quarterly user charges for the domestic user class. The
domestic (residential) user charge paid to the City each quarter will
be the user charge calculated for the winter quarter. The quarterly
user charge paid to the City for each domestic user is determined as
follows:
Domestic (Residential) User Charge =
UCR x Total Metered Water Gallonage for the Winter Quarter
'JI ,25U"
* 91,250 = 1,000 gallons/day x 91.25 days/quarter
14. Establish quarterly user charges for the commercial, institutional,
and governmental user classes. The user charge rate UCR as determined
in Step 12 will be used for all quarters. The user charge will vary
each quarter dependent on the quantity of water usage. The quarterly
user charge paid to the City is determined as follows:
Commercial User Charge =
UCR r. Total Metered Water Gallonage for the Quarter
91,250
Institutional User Charge =
UCR x Total Metered Water Gallonage for the Quarter
91,250
Governmental User Charge =
UCR x Total Metered Water Gallonage for the Quarter
91,250
15. Establish quarterly user charges for industrial class users. The
annual unit charge rates Q (R) , BOD (R) , and SS (R) as determined in
Step 10 will be used for all quarters. The user charge will vary
each quarter dependent on the quantity of water and strength of BOD
and SS loadings discharged by the user into the system. The quantity
user charge paid to the City is determined as follows:
Industrial User Charge =
(Q(I) x 2(R) ) + (ROD (I) x BODF, (R) + (SS (I) x SS (R) )
4 4 4
Q(I) = Average metered water gallonage for the quarter (1000 gpd)
BOD5(I) = Average measured BOD5 loading for the quarter (#/day)
SS(I) = Average measured SS loading for the quarter (#/day)
(B) For the purpose of this Ordinance, commercial, institutional, and
governmental users shall have their user charge computed quarterly based
upon actual metered water gallonage for the quarter being charged. In-
dustrial user charges are computed quarterly on the basis of metered
water gallonage, measured BODS and suspended solids for the quarter being
charged. User charges for domestic (residential) users shall be computed
once per year. The domestic user charge will be based upon winter quarter
metered water gallonage. The domestic user charges for the three quarters
following the winter quarter will be the same as computed for the winter
quarter regardless of actual water use. User charge rates used for all
quarters are computed on the basis of the winter quarter measurements for
domestic users and annual average measurements for all other classifica-
tions. These rates shall be re -computed annually. The user charges are
computed as per previous subsection 7-3-2 (A) .
(C) In any case where metered water gallonage or discharged waste disposal
gallonage cannot be fairly and equitably determined, the Director of Public
works shall estimate or determine the gallonage based upon other available
information or measurements.
(D) At the option of the user, actual waste disposal gallonage discharged
into the sewer system may be applied in lieu of metered water gallonage
for computation of the user charge. It is the responsibility of the user
to install and maintain the discharge measuring device and provide access
to the City staff as necessary.
7-3-3: BILLING AND ENFORCEMENT PROCEDURES
(A) The City Clerk shall compute the amount due the City for service
charges and render a statement thereof quarterly to the owner or occupant
of any premises served, or to both. Charges in accordance with Section 7-3-2
may be billed on a monthly basis. All amounts due hereunder shall be pay-
able to the office of the City Clerk.
(B) A connection, once made, shall not nevertheless, thereafter be continued
in use, except and unless there is paid and received by the City with respect
to such connection a sum of money at least equal to the "user charge" imposed
and to be collected by the City (with respect to such connection) for each
quarterly period of time that such connection exists. Such "user charge"
shall be promptly paid when due by the owner or occupant of the premises
affected directly to the City for the quarterly period of use represented
by such payment.
(C) Enforcement of Charges. Each charge levied by and pursuant to this
section is hereby made a lien upon the corresponding lot, land, or premises
served by a connection to the sewer system of said city and all such charges
which are on the first day of September of each year more than 90 days past
due, and having been properly billed to the occupant of the premises served,
shall be certified by the City Clerk to the County Auditor between the 1st
and 10th day of October of each year and the City Clerk in so certifying
such charges to the County Auditor shall specify the amount thereof, the
description of the premises served, the name of the owner thereof and the
amount so certified shall be extended by the auditor on the tax rolls against
such premises in the same manner as other taxes, and collected by the county
treasurer, and paid to the city treasurer, along with other taxes.
- 4 -
(D) Right of Action. Any charges, levied by and pursuant to section 7-3-2,
and which have been properly billed to the owner or occupant of any premises
served, and not paid, may be recovered in a civil action, by the city in any
court of competent jurisdiction.
(E) Application of Funds. The funds received from the collection of charges
authorized by this section shall be deposited as collected, in a fund known
as the Sewer Fund and shall be disbursed: (a) to meet the costs of operation
and maintaining the sewage disposal pumping stations, treatment plant, and
collection system; (b) to meet the costs of repair and replacement of the
sewage disposal facilities.
7-3-4: INSPECTION AND CONTROL
(A) Industrial Waste Measurement and Sampling. Any person discharging in-
dustrial waste into the disposal system shall provide and maintain a suitable
point or points of access together with such necessary meters and other
appurtenances at an appropriate location prior to discharge of the waste into
the disposal system to permit observation, measurement, and sampling of such
waste by the city. Plans for such sampling points and measuring equipment
shall be submitted -to and approved by the City prior to construction and
installation of same. Sampling and measuring facilities shall be such as to
provide safe access .for making inspection and verification of their proper
operating condition. The metered water supply to a source of industrial
waste may be used in lieu of a measured industrial waste volume where it can
be established that the metered water supply and waste quantities are approxi-
mately the same, or where a measurable adjustment to the metered supply can be
made to determine the waste volume.
(B) Industrial Waste Analyses. Determination of the character and con-
centration of an industrial waste discharged into the disposal system shall
be made by the person discharging it or his designated agent. Reports showing
quantities and pertinent analytical data of such industrial waste discharges
shall be filed. with the city.
(C) Measurement and Test Procedures. All measurements, tests, and analyses
of the characteristics of waste to which reference is made in these rules
and regulations shall be determined in accordance with the latest edition of
"Standard Methods for the Examination of Water and Wastewater", published
jointly by the American Public Health Association, the American Water Works
Association and The Water Pollution Control Federation. Sampling shall be
carried out by methods acceptable to and approved by the City. Alternate
methods for certain analyses may be used subject to prior written approval
by the City.
- 5 -
(n) Confidentiality of Critical Information. Any records or other infor-
ma-tion obtained by the City or furnished by an industrial waste discharger
which are certified by said discharger to relate to (a) production or sales
figures, (b) processes or production unique to the discharge, or (c) infor-
mation which would tend to affect adversely the competitive position of said
discharger, shall be only for the confidential use of the City in discharging
its statutory obligations unless otherwise authorized by the said discharger.
However, all such information may be used by the City in compiling or pub-
lishing analyses or summaries relating to the general condition of the
public waters so long as such analyses or summaries do not identify any dis-
charger who has so not certified.
