(10) Any waters or wastes having a five-day BOD greater than 300 milligrams per liter, or containing more than 350 milligrams per liter of suspended solids, or having an average daily flow greater than two percent of the average wastewater flow of the city shall be subject to the review of the superintendent. Where necessary, in the opinion of the superintendent, the owner shall provide, at the owner’s expense, such preliminary treatment as may be necessary to reduce the BOD to 300 milligrams per liter, or reduce the suspended solids to 350 milligrams per liter, or control the quantities and rates of discharge of such waters or wastes.

(1)   Reject the wastes;

(2)   Require pretreatment to an acceptable condition for discharge to the public wastewater collection system;

(3)   Require control over the quantities and rates of discharge; and/or

(4)   Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or user charges.

If the superintendent permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the superintendent and subject to the requirements of all applicable codes, ordinances and laws.

If no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of the constituents upon the treatment works and to determine the existence of hazards to life, limb and property. (The particular analyses involved will determine whether a 24-hour composite of all building sewers of premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from 24-hour composites of all building sewers whereas pH’s and heavy metals are determined from periodic grab samples.)

(Code 1971, § 26-118)

Any pretreatment standards as established by state, federal or other public agencies of jurisdiction for such discharge will be used as the minimum requirements by the superintendent as applied to this article.

This meter shall serve as a control for the establishment of the sewer user charge and shall be accessible to the city’s meter readers.

(Code 1971, § 26-147)

Where more than one water meter is installed for service to one industry or commercial business located at a single site or adjoining sites, only one minimum monthly charge shall apply.

(Code 1971, § 26-148)

Where it can be established that a contributor has had a water leak during the establishment of the contributor’s average water use, the contributor’s charge may be adjusted by the cashier of the utility office by using the previous month average water use or portion thereof.

(Code 1971, § 26-149)

If wastewater service is commenced or terminated during a period for which bills are rendered, billing shall be prorated on a daily basis.

(Code 1971, § 26-150)

(Code 1971, § 26-153)

Any user shall be assessed a surcharge, in addition to any sewer service charges, if the waste discharged by this user has concentrations greater than normal domestic wastewater as defined in section 20-201. The user’s surcharge shall be calculated by the following formula:

Cu = (Vc)(Vu)+ (Bc)(Bu)+ (Sc)(Su)+ (Pc)(Pu)


Cu = A user’s surcharge per unit of time.

A third account may be established and shall contain all other revenues generated through sewer service charges.

(Code 1971, § 26-155)

Revenues placed in the operation and maintenance (O&M) account shall be used only for meeting O&M costs; all revenues placed in the replacement account shall be used only for replacement costs as defined in section 20-101. All revenues borrowed from any other account which are used to meet O&M or replacement costs shall be repaid the following year by adjusting sewer service charges, if necessary.

(Code 1971, § 26-156)

Whenever current standards or guidelines are altered by any governmental agency in such a manner as to cause expansion and/or upgrading of the treatment works, sewer service charges must be adjusted in accordance with the current guidelines to reflect the costs of expanding and/or upgrading the treatment works.
