13.02.400 Reimbursement agreement—Purpose.

Whenever the construction of a main sewer line within the city at private expense (other than through assessment district proceedings) is completed after November 5, 1974 and the city manager finds that such main sewer line, when so contracted, potentially will serve properties of persons other than those paying the cost of construction thereof, partial reimbursement of construction cost will be determined as provided herein. (Ord. 250 § 610 (part 1), 1974).

13.02.410 Reimbursement agreement—Application.

Any person, firm or corporation proposing to construct, extend or over-size above an eight-inch diameter sewer line shall make application to the city manager for a certificate of entitlement to reimbursement. If the city manager finds that such sewer line to be constructed may reasonably be expected to benefit properties owned by persons other than those proposing to construct it and that the final construction costs as shown by itemized statements submitted are reasonable, he may recommend to the city council that a certificate of entitlement to reimbursement be granted to the applicant. If the council concurs in the recommendation of the city manager, it may by resolution, declare the applicant entitled to partial reimbursement for construction costs. In the event of disagreement with the findings or recommendations of the city manager, the applicant may appeal directly to the council for final determination.

It will not include office engineering or overhead cost, easement costs or any other items of cost not listed immediately above. (Ord. 314 § 3, 1979: Ord. 250 § 610 (part 4), 1974).

13.02.440 Reimbursement agreement—Terms of payment.

When a person is granted a certificate of entitlement to reimbursement, the exact amount to be reimbursed, the method for determining contributions toward reimbursement from those benefiting from the construction and the terms for payment to the person by the city, shall be the subject of a special contract between the city and the person constructing, extending or oversizing a sewer. Partial reimbursement of privately financed sewers qualifying under the terms of this chapter shall be accomplished by fees collected by the city upon connection to the subject sewer by those benefiting from it. Fees shall be based upon the construction costs of the sewer divided according to property frontage along the alignment of the sewer or the pro rata share of the sewer’s capacity used by those connecting to it, or a combination of both, as determined by the city manager and approved by the city council. (Ord. 314 § 4 (part), 1979: Ord. 610 (part 5), 1974).

13.02.450 Reimbursement record.

The city manager will maintain a reimbursement record in which fees owed, collected and disbursed in accordance with the contract between the city and the applicant will be accounted for by project designation and applicant. In January of each year, after the effective date of this chapter, a review of each reimbursement record will be made to determine the pro rata share which each applicant is entitled to, which has not been reimbursed. The pro rata share of entitlement to reimbursement will be adjusted by the ratio of the current construction cost index to that prevailing at the time of construction, which will be applied on the amounts which have not been reimbursed. The construction cost index shall be as published by McGraw-Hill, Inc., in “Engineering News Record.” The amounts of reimbursement will not be altered; only the pro rata shares. Reimbursement will then be made based on the adjusted pro rata shares. (Ord. 314 § 4 (part), 1979: Ord. 610 (part 6), 1974).

13.02.460 Reimbursement agreement—Designation of payee.

The city reserves the right in granting a certificate of entitlement to reimbursement to require that a payee be named to act for and on behalf of all persons, firms or corporations interested in reimbursement where the applicant is other than an individual.

As used herein, “slug” means any discharge of water, sewage or waste which in concentration of any given constituent or in quantity of flow exceeds for any period of duration longer than fifteen minutes more than five times the average twenty-four-hour concentration or flow during normal operation;

J. Wastes containing substances which are not amenable to treatment by the sewage treatment process employed, or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of the California Regional Water Quality Control Board, Central Valley Region. (Ord. 250 § 703, 1974).

13.02.520 Acceptance of deleterious wastes.

If any wastes containing the characteristics listed in Section 13.02.510, which in the judgment of the city manager may have a deleterious effect upon the sewerage works, process, equipment or receiving water, is to be discharged to a public sewer, the city manager may do one or more of the following:

Grease interceptors, including grease traps, are grease removal devices that interrupt the flow of wastewater, allowing grease and solids to separate out before the wastewater enters the public sewer system. Interceptors shall conform to the following:

A. The size of grease interceptors shall be determined as described in the Uniform Plumbing Code and as approved by the city.

B. Interceptors shall be so installed and connected that they shall be at all times easily accessible for inspection, sample collection, cleaning and removal of grease and other ingredients.

C. Waste discharge from fixtures and equipment in establishments which may contain grease or other objectionable materials including, but not limited to, scullery sinks, pot and pan sinks, dishwashers, food waste disposals, soup kettlers, and floor drains located in areas where such objectionable materials may exist may be drained into the sanitary waste through the interceptor when approved by the city; provided, however, that toilets, urinals, wash basins, and other fixtures containing fecal material shall not flow through the interceptor.

D. Discharges entering interceptors shall not exceed one hundred ten degrees Fahrenheit.

E. Abandoned interceptors shall be emptied and filled as required for abandoned septic tanks. (Ord. 739 (part), 2013: Ord. 250 § 706, 1974).

The discharger shall develop and maintain a record of periodic maintenance and pumping of the grease interceptor. Records shall be retained for a period of not less than three years. A copy of the cleaning record shall be maintained at the facility and made available to the city upon request.

Pumping shall be sufficiently frequent to prevent objectionable odors, surcharge of the removal device causing pass-through or interference with the operation of the sanitary sewer system.
