(a) 
All users shall be classified by assigning each one to a "user classification" category according to the principal activity conducted on the user's premises as follows:
(1) 
Significant industrial users;
(2) 
Commercial users:
(A) 
Standard strength,
(B) 
High strength,
(C) 
Low strength;
(3) 
Residential.
(b) 
The purpose of such classification is to facilitate the regulation of wastewater discharges based on wastewater constituents and characteristics, to provide an effective means of source control, and to establish a system of user charges and fees which will ensure an equitable recovery of the city's costs. The classifications listed in this section shall be in effect upon the effective date of the 2001 Wastewater Rate Resolution.
(Ord. 2129-84 § 1; Ord. 2490-94 § 1; Ord. 2661-01 § 11)
(a) 
All types of commercial users who do not fall within the definitions contained in Section 12.04.030(6)(b) (i—iii) or 12.04.030(6)(c)(i—iv) shall, at the time the classifications contained in this ordinance become effective as set forth in Section 12.16.010(b) herein, be initially presumed to fall within the "standard strength" classification.
(b) 
The director may determine that a change in classification is appropriate for any commercial user initially presumed to be in the "standard strength" category after the water pollution control plant staff have conducted not less than four random samplings of the commercial facility over a period of one year, at approximately quarterly intervals, and where the average of such samplings indicates that the user falls within either the high strength or low strength category. In such event the Director shall give notice to the commercial user of such change of classification, and the user shall thereafter incur charges for sewer usage based upon the rates for such revised category established by the city council.
(c) 
The classification for any newly established commercial user after the effective date of this ordinance, which user does not fall within the definitions contained in Section 12.04.030(6)(b)(i—iii) or 12.04.030(6)(i—iv) shall initially be determined to be the "standard strength" classification for rate purposes, until a similar sampling process as described in subsection (b) herein has taken place. Based upon such sampling the classification may be later changed upon notice by the director.
(Ord. 2661-01 § 12)
The city council from time to time shall establish by resolution fees and charges for sewage services provided by the city. Such fees and charges shall be based on cost influencing factors such as flow, pollutant loading rates, volumes, and the degree of effort required for purposes of billing, inspection, sampling, testing and permitting.
(a) 
Significant Industrial Users. Industrial users who are significant industrial users under the provisions of Chapters 12.04 through 12.18 shall pay a user charge determined by wastewater constituents and/or characteristics, as determined by resolution of the city council, if the discharge has a pollutant loading greater than the equivalent of standard strength.
(b) 
All Other Users. All other users shall pay a fixed unit charge as set forth in the city's schedule of user charges and fees, pursuant to council resolution. In addition to user fees and charges as approved by the city council fees and charges may include but are not limited to:
(1) 
Fees to recover the costs of application processing, user classification, inspection and monitoring. Fees may be assessed for the following:
(A) 
Stormwater or groundwater drainage connection,
(B) 
Operation of garbage grinder,
(C) 
Determination and approval of use of metered or estimated diversion water or discharge wastewater volumes for billing purposes,
(D) 
Wastewater discharge permit,
(E) 
Interim wastewater discharge permit,
(F) 
Review of proposals for protection against accidental discharges,
(G) 
Such other services expressly or reasonably required to be performed pursuant to this chapter and specified by resolution establishing the fees herein authorized;
(2) 
Appeal fees to recover the administrative cost of processing appeal filing. Fees shall be assessed at the time the appeal is filed;
(3) 
Service charges to recover the costs of operation and maintenance (including replacement) to satisfy provisions of the Federal Water Pollution Control Act and any other sewerage system related costs appropriately recoverable via service charges;
(4) 
Connection charges.
