A. Each user shall pay for the services provided by the city based on use of the treatment works as determined by water meter(s) acceptable to the city.

B. 1.  For all residential and small nonresidential contributors, monthly user charges will be based upon the average usage during the consecutive months of December, January, and February of each year. If a residential contribution has not established a December, January and February average, his or her monthly user charge shall be the median charge of all other residential contributors.

2. All large nonresidential monthly user charges shall be based on the monthly water usage metered each month.

If a commercial or industrial contributor has a consumptive use of water, or in some manner uses water which is not returned to the wastewater collection system, the user charge for that contributor may be based on a wastewater meter(s) or separate water meter(s) installed and maintained at the contributor’s expense, and in a manner acceptable to the city. The meter(s) shall be open and available for inspection and reading by an authorized city representative.

C. Effective for the February 1, 2006 billing cycle and appearing on the March 2006 billing:

The readiness-to-serve monthly charge per month shall be six dollars and fifty cents ($6.50). In addition, each contributor shall pay a user charge rate for operation and maintenance including replacement and a portion of debt service of two dollars and thirty-two cents ($2.32) per one hundred (100) cubic feet of water used as determined in this section.

D. For contributors who contribute wastewater, the strength of which is greater than normal domestic waste as defined in Section 13.20.020 of this chapter, a surcharge in addition to the normal user charge will be collected. The surcharge for operation and maintenance including replacement is:

1. $0.120 per pound BOD;

2. $0.073 per pound SS.

E. The readiness-to-serve monthly charge for rural sanitary sewer districts shall be one hundred fifty (150) percent of the readiness-to-serve charge for users in the city for each customer served by the rural sewer district. All wastewater discharged through the rural sewer district’s metering device shall be charged at a rate of one hundred fifty (150) percent of the monthly charge for users inside the city limits.

F. For all users or customers outside the city, other than those involving rural sanitary sewer districts, but in additions platted since January 1954, or users entitled to the use of the city’s sewer disposal system by virtue of contract, the readiness-to-serve monthly charge shall be the same as specified in subsection (E) of this section. The amount of wastewater discharged by these users shall be determined by one of the following methods:

1. A metering device(s) approved by the city, which measures the total amount of water used on the premises. The monthly sewer service charge shall be based on the average monthly water usage during the months of December, January and February of each year;

2. A metering device(s), approved by the city, which measures the total amount of wastewater discharged by the user.

G. Any user which discharges any toxic pollutants which cause an increase in the cost of managing the effluent or the sludge from the city’s treatment works, or any user which discharges any substance which singly or by interaction with other substances causes identifiable increases in the cost of operation, maintenance or replacement of the treatment works, shall pay for such increased costs. The charge to each such user shall be as determined by the director of public utilities and approved by the governing body. (Ord. G-986 § 1, 2006; Ord. G-977 § 1, 2006; Ord. G-953 § 1, 2003; Ord.
