(A) Detailed construction plans and specifications for proposed public and private sewers to be constructed and directly connected to the city sewerage system shall be prepared by a registered professional engineer and shall be subject to review and approval by the city. Each local government agency and person shall notify the city in writing of its intention to prepare such construction plans and specifications delineating the boundaries of the areas to be sewered by map, sketch, or written description. Within ten calendar days following receipt of such notice, the city shall make written request for the submission of such plans and specifications. The local government agency or person shall submit two sets of plans and specifications and shall obtain approval thereof and a permit to construct prior to advertising for bids.
(B) Within 21 calendar days following receipt of such plans and specifications, the city shall review same and return one set thereof to the local government agency or person with approval or required changes indicated. If said plans and specifications are disapproved, the required changes shall be made by the local government agency or person, and all required revisions of plans and specifications resubmitted in the same manner as provided for the initial submittal. In the event no communication is received from the city by the local government agency or person within 21 calendar days of the date of submission of such plans and specifications, it shall be deemed that the city has approved such plans and specifications and will issue a construction permit.
(Ord. 46, passed 4-8-1975)
(A) General. The construction of new public sewers and private sewers to be connected to the city sewerage system, and extensions of existing sewers within the city boundaries shall fully conform to these rules and regulations, construction standards, and the requirements of the appropriate state agency. In the event of conflict, the highest applicable standard shall govern.
(B) Type of sewerage system. New public sewers, private sewers, and extensions of existing sewers shall be designed as separate sanitary sewers or storm sewers. Construction of combined sewers will not be permitted.
(C) Flow allowances. The design criteria for new public sewers, private sewers, and extensions of existing sewers shall be such that the total daily flow other than sewage shall be 1,000 gallons per acre per day.
(D) Inspection.
(1) The city will provide a full-time inspector or inspectors on all new sanitary sewer construction within the city and for those sewers connected to the city sewerage system to ensure compliance with these rules and regulations and the specifications under which they are to constructed. The inspector(s) will make diligent efforts to guard the city against defects and deficiencies in the work of the contractor(s) and to help determine if the provisions of theses rules and regulations and the construction standards are being fulfilled. Inspection will not, however, cause the city to be responsible for those duties and responsibilities which belong to the construction contractor and which include, but are not limited to, full responsibility for the techniques and sequences of construction and the safety precautions, incidental thereto, and for performing the construction work in accordance with these rules and regulations and the construction standards.
(2) The city will notify the local government agencies or persons responsible for the construction when, in the opinion of the city, the construction work does not comply with these rules and regulations. Upon receipt of notification from the city that any sewer construction work is not being performed in compliance with these rules and regulations and to the construction standards therefor, the local government agency or person shall immediately take such action as may be necessary to ensure compliance. Each local government agency or person shall inform the city a minimum of ten but not more than 20 days in advance of the start of any sewer construction.
(3) The city shall be reimbursed for the cost of providing inspection services by the local government agency or person installing new sanitary sewers. The cost for inspection services shall be on a per diem basis determined by the secretary at the time the permit (§ 52.006 of this subchapter) is issued to perform the work.
(4) The construction of the sewers shall be under the supervision of an engineer currently registered in the state or his or her representative. At the completion of the construction, the engineer shall certify in writing to the city that such construction complies with these rules and regulations and plans and specifications therefor.
(E) Construction standards. Construction of local government agency or private sanitary sewers to be connected to the city sewerage system shall conform to these rules and regulations and to the standards for sanitary sewer construction in the city (construction standards), together with all amendments thereof or hereafter adopted. Copies of the construction standards are available at the office of the secretary.
(Ord. 46, passed 4-8-1975)
(A) Approval required. No connection shall be made to the city sewerage system without the prior approval of the city.
(B) Sewer connection to city system. Sewers shall be planned so as to require the minimum practical number of points of connection to the city system.
(C) Sewer surcharges.
(1) An additional charge will be made for quantities of water other than sewage and industrial waste in excess of the volume established for design purposes in § 52.007(C) of this subchapter. Any charge made in addition to the regular charge shall be based on metered records of flow taken and compiled by the city.
(2) To determine when quantities of water other than sewage and industrial waste entering the city’s sewerage facilities become excessive, the city may meter and record flows from suspected areas between the hours of 2:00 a.m. and 4:00 a.m. The flows during this period, less a 10% allowance for possible night-time use of the system, shall be assumed to be water other than sewage and industrial waste. If this amount exceeds the allowance as set forth in § 52.007(C) of this subchapter, the area shall be deemed to be contributing excessive flow. Significant commercial activity during the test period, such as manufacturing, will be metered at the source and subtracted from the above metered flows to arrive at the quantity of water other than sewage and industrial waste.
(3) If the city elects to meter and record total daily flow from such sewers, the local government agency or person will be given at least five days’ notice in advance of such metering. Metering periods shall continue until excessive flow conditions are corrected.
(4) Daily surcharges for excess flow will be as established by the Directors in the rate schedules.
(Ord. 46, passed 4-8-1975)
(A) Prohibited discharges. No person shall discharge, directly or indirectly, into a public sewer any material or substance which is prohibited by any rules and regulations of the city. No person shall discharge any material whatsoever into a city manhole through the top.
(B) Interference with operation of city system. No unauthorized person shall enter any city sewer, manhole, pumping station, treatment plant, or appurtenant facility.
(1) No person shall maliciously, willfully, or negligently break, damage, destroy, deface, or tamper with any structure, appurtenance, or equipment which is part of the city system.
(2) No person, other than an authorized employee or agent of the city shall operate or change the operation of any city sewer, pumping station, treatment plant, or appurtenant facility.
(Ord. 46, passed 4-8-1975) Penalty, see § 52.999
Any local government agency or person feeling himself or herself aggrieved by any decision or action of the city made or taken pursuant to these rules and regulations may appeal to the Directors by filing written notice of appeal with the secretary within 45 days following such decision or action. Such notice of appeal shall set forth in reasonable detail the action or decision appealed from the appellant’s ground for reversal or modification thereof. Within 20 days following receipt of such notice, the Directors shall set a time for hearing upon such appeal which shall not be less than ten nor more than 40 days following such receipt. The action of the Directors upon such appeal shall be conclusive, subject to appeal in the manner required by law.

(A) No statement contained in this subchapter shall be construed as prohibiting any special agreement or arrangement between the city and any person whereby an industrial waste of unusual strength or character may be admitted to the sewage disposal works, either before or after pre-treatment, provided that there is no impairment of the functioning of the sewage treatment works by reason of the admission of such wastes, and not extra costs are incurred by the city without recompense by the person.
(B) If any waters or wastes are discharged, or are proposed to be discharged to the city sewers, which waters contain the substances or possess the characteristics enumerated in §§ 52.026 and 52.027 of this subchapter, and which, in the judgment of the secretary, may have a deleterious effect upon the sewage works, processes, equipment, or which otherwise create a hazard to life or constitute a public nuisance, the city may:
(1) Reject the wastes;
(2) Require pretreatment to an acceptable condition for discharge to the public sewers, including a minimum of two hours of settling for wastes containing soil, dirt, and/or sand;
(3) Require control over the quantities and rates of discharge, by the construction of equalization basins or by other appropriate methods; or
(4) Require payment to cover the added cost of handling and treating the wastes not covered by existing sewer charges under the provisions of §§ 52.008 and 52.080 through 52.084 of this chapter.
