[R.O. 1988 § 35-123; Ord. No. 2886 § 3, 12-7-1992]
It is determined and declared to be necessary and conducive to the protection of the public health, safety, welfare and convenience of the City of Rolla to collect charges from all users who contribute wastewater to the City's treatment works. The proceeds of such charges so derived will be used for the purpose of operating, maintaining and retiring the debt of such public wastewater treatment works.
[R.O. 1988 § 35-125; Ord. No. 2136 § 2, 2-12-1979; Ord. No. 2886 § 3, 12-7-1992; Ord. No. 3486 § 2, 11-5-2001; Ord. No. 3881 § 2, 10-20-2008; Ord. No. 4379 § 2, 11-20-2017; Ord. No. 4515 § 2, 9-16-2019; Ord. No. 4697 § 4, 9-19-2022]
The wastewater service charge for the use of and for service supplied by the wastewater facilities of the City of Rolla shall consist of a service availability fee for the operation and maintenance of the collection system and a basic wastewater treatment user charge for wastewater treatment operation, maintenance and replacement, sewer system reserve fund, and a surcharge rate for BOD and SS.
(a) 
The service availability fee shall be based on the estimated cost for the collection system operation, maintenance and replacement costs.
(b) 
The basic wastewater treatment user charge shall be based on water usage as recorded by water meters having the following normal concentrations:
(1) 
A five-day, twenty degrees Centigrade (20° C.) biochemical oxygen demand (BOD) of two hundred fifty (250) mg/L.
(2) 
A suspended solids (SS) content of three hundred (300) mg/L.
(c) 
It shall consist of treatment operation, maintenance and replacement costs plus sewer system reserve fund costs and shall be computed as follows:
(1) 
Estimate the projected annual revenue required to operate and maintain the wastewater facilities, including a replacement fund for the year and a sewer system reserve fund, for all works categories.
(2) 
Proportion the estimated costs to wastewater facility categories by volume, suspended solids and BOD, if possible.
(3) 
Estimate wastewater volume, pounds of SS and pounds of BOD to be treated.
(4) 
Proportion the estimated costs of non-industrial users by volume, suspended solids and BOD.
(5) 
Compute costs per 1,000 gallons for normal sewage strength.
(6) 
Compute surcharge costs per pound and BOD and SS in excess of normal sewage strength.
(d) 
A surcharge will be levied to all users whose wastewater exceeds the normal concentrations for BOD [two hundred fifty (250) mg/L and SS (300 mg/L)]. The surcharge will be based on water usage as recorded by water meters and/or sewage meters for all wastes which exceed the two hundred fifty (250) mg/L and three hundred (300) mg/L concentration for BOD and SS respectively. Section 35-129 specifies the procedure to compute a surcharge.
(e) 
That portion of the total user charge collected which is designated for operation and maintenance including replacement purposes as established in Section 35-126, shall be deposited in a separate non-lapsing fund known as the Operation, Maintenance and Replacement Fund and will be kept in two (2) primary accounts as follows:
(1) 
An account designated for the specific purpose of defraying operation and maintenance costs (excluding replacement) of both collection and treatment works (Operation and Maintenance Account).
(2) 
An account designated for the specific purpose of ensuring replacement needs over the useful life of the treatment works (Replacement Account). Deposits in the replacement account shall be made annually from the operation, maintenance and replacement revenue in the amount of two hundred seventy-two thousand one hundred eighty-nine dollars ($272,189.00) annually.
(f) 
The adequacy of the service availability fee and the wastewater service charge shall be reviewed annually by accountants for the City of Rolla and presented in their annual audit report. The service availability fee and the wastewater service charge shall be revised periodically to reflect a change in operation and maintenance costs, replacement costs, or the sewer system reserve fund.
(g) 
The City will review the user charge system every year and revise user charge rates as necessary to ensure that the system generates adequate revenues to pay the costs of operation and maintenance including replacement and that the system continues to provide for the proportional distribution of operation and maintenance including replacement costs among users and user classes.
(h) 
The City will notify each user at least annually, in conjunction with a regular bill, of the rate being charged for operation, maintenance including replacement of the treatment works.
(i) 
The volume of flow used for computing basic user charges and surcharges shall be the metered water consumption read to the lowest even increment of one thousand (1,000) gallons.
(1) 
If the person discharging wastes into the public sewer procures any part, or all, of their water from sources other than the City of Rolla Water System, all or a part of which is discharged into the public sewers, the person shall install and maintain, at their expense, water meters of a type approved by the Public Works Director for the purpose of determining the volume of water obtained from these other sources.
(2) 
Devices for measuring the volume of waste discharged may be required by the Public Works Director if these volumes cannot otherwise be determined from the metered water consumption records.
(3) 
Metering devices for determining the volume of waste shall be installed, owned and maintained by the person. Following approval and installation such meters may not be removed, unless service is cancelled, without the consent of the Public Works Director.

Where:
V is the volume of wastewater in 1000 gallons discharged by the extra strength user during the month.
Unit flow charge is in $/1,000 gal from Section 35-126.
Unit BOD charge is in $/lb BOD from paragraph 4 Unit SS charge is in $/lb SS from paragraph 4.
BOD is the normal BOD strength in milligrams per liter (mg/L) as defined in Section 35-1.
