All interceptors shall be of a type and capacity approved by the superintendent and shall be located as to be readily and easily accessible for cleaning and inspection. Where preliminary treatment or flow-equalizing facilities are required or permitted for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense. When required by the superintendent, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters and other appurtenances in the building sewer, to facilitate observation, sampling, and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the superintendent. The manhole shall be installed by the owner at his or her expense, and shall be maintained by him or her so as to be safe and accessible at all times.

In the event that 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 sewage 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 a 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.)

The superintendent or his or her representatives shall have no authority to inquire into any processes including metallurgical, chemical, oil, refining, ceramic, paper, or other industries beyond that point having a direct bearing on the kind and source of discharge to the sewers or waterways or facilities for waste treatment.

Samples and measurements will be taken by the City at times and utilizing methods as required by the superintendent or their authorized representative. Such inspection may include random grab testing. The strength of the sewage discharge by the industrial or commercial user will be determined by the analyses of said samples. BOD levels disclosed by such testing will be applied to each day of the corresponding billing cycle. The user shall be responsible for all costs of testing and inspection if testing reveals any prohibited discharges under this article.

The user, at their expense, may be required at the sole discretion of the superintendent to provide monitoring and flow measurement facilities which coincide at the point at which effluent limits apply. Sampling locations must be safe, convenient, and accessible to the industrial user and City utilities personnel.

If any industrial or commercial user chooses not to accept the analytical determination made by the City for a billing period, such user shall, prior to the date on which payment of the charges for such billing is due, notify the superintendent in writing and, at their sole expense, employ an independent laboratory which is certified by the Kansas Department of Health and Environment and acceptable to the superintendent, to conduct sampling and analysis of their sewage.

The time period, location, and method for the collection of the samples shall be designated by the City. The City and the independent laboratory shall both preside over the collection of the samples and shall equally divide the samples so that duplicate analysis may be performed.

If results of the analysis of the sewage sample made by both the City and the independent laboratory are not comparable, the superintendent may appoint a second independent laboratory certified by the Kansas Department of Health and Environment to analyze the sewage. The sampling procedures used will be the same as those outlined above. The results of these analyses, together with the previous results, shall be used to determine the actual extra strength charges for the subject billing period. The fee for the second independent laboratory analyses shall be paid for by the user.

When regulations, Federal, State or City, require monitoring of the waste from an industry, that industry shall pay a monitoring charge.

The monitoring charge shall consist of all costs for personnel, material and equipment used to collect and analyze samples from the user’s wastewater. The exact charge shall be based on actual costs and shall be determined by the superintendent.

(a)   The monthly base rate shall be $31.68.

(b)   The volume rate for residential users shall be $3.98 per 1,000 gallons until May 1, 2024 and $4.38 per 1,000 gallons thereafter.

(c)   The volume rate for all other user groups shall be $4.38 per 1,000 gallons.

(d)   For residential customers the amount of water used for billing purposes shall be determined by an average of water used per billing period for mid-December to mid-January (February bill) through mid-February to mid-March (April bill) billing periods. The average use shall be computed in April of each year for residential sewage utility customer. The average shall be applied against the above rate structure effective with the May sewage billing and shall remain constant for future billings until the average water used is recalculated in the following April.

(e)   All non-residential users’ charges shall be based on the water metered during the current billing cycle.
