(A) There shall be two (2) classes of building sewer permits required; (1) for residential and (2) for service to commercial and industrial establishments. In either case, the owner(s) or his agent shall make application on a special form furnished by the city. Applicants for a service to commercial and industrial establishments shall be required to furnish information about all waste producing activities, wastewater characteristics and constituents. The permit application shall be supplemented by any plans, specifications, or other information considered pertinent in the judgment of the superintendent. Details regarding commercial and industrial permits include, but are not limited to those required by this chapter. Permit and inspection fees shall be paid to the city at the time the application is filed.
(B) Users shall promptly notify the city in advance of any introduction of wastewater constituents or any substantial change in the volume or character of the wastewater constituents being introduced into the POTW. The superintendent may deny or condition the new introduction or change in discharge based on the information submitted in the notification or additional information as may be requested.
(C) No person(s) shall uncover, plug or make any connection with or opening into, use, alter, or disturb any public sewer or appurtenance thereof without first obtaining permission from the superintendent.
(Ord. No. 17-91, 6-25-91)
(A) No person shall make connection of roof downspouts, basement wall seepage or floor seepage, exterior foundation drains, areaway drains, or other surface runoff or groundwater to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sewer. Any such connections which already exist on the effective date of this chapter shall be completely and permanently disconnected within sixty (60) days of the effective date of this chapter. The owner(s) of any building sewers having such connections, leaks or defects shall bear all costs incidental to removal of such sources. Pipes, sumps, and pumps for such sources of ground and surface water shall be separate for wastewater facilities. Removal of such sources of water without presence of separate facilities shall be evidence of drainage to public sanitary sewer.
(B) Floor, basement, or crawl space drains which are lower than ground surfaces surrounding the building shall not be connected to the building sanitary sewer. No sanitary inlet which is lower than six (6) inches above the top of the lowest of the two (2) adjacent public sanitary sewer manholes shall be connected by direct drainage to the building sanitary sewer. Building sanitary sewer connections in structures not meeting the criteria of this section will be permitted only if the property owner has:
(1) Installed an individual pumping facility at the structure to receive the building sewage. The pumping facility shall include a discharge pipe with a high point which meets the criteria above; or,
(2) Installed a sewer backflow stop or flap of such nature and design to provide gravity flow to the sanitary sewer system and to prevent sewage backflow into the property improvement.
(Ord. No. 17-91, 6-25-91)
(A) A separate and independent building sewer shall be provided for every building; except where one building stands at the rear of another on an interior lot and no private sewer is available or can be constructed to the rear building through an adjoining alley, courtyard, or driveway. The sewer from the front building may be extended to the rear building and the whole considered as one building sewer, but the city does not and will not assume any obligation or responsibility for damage caused by or resulting from any such single connection aforementioned.
(B) Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the superintendent, to meet all requirements of this chapter. Permit and inspection fees for new buildings using existing building sewers shall be the same as for new building sewers. If additional sewer customers are added to the old building sewers, additional sewer tap fees shall be charged accordingly even though no new sewer tap is actually made into the city system.
(C) Extension of customer service lines from any point on the customer's side of the tap for delivery of waste from any location other than that of the customer in whose name the tap is registered shall not be permitted.
(D) The building sewer shall be cast iron soil pipe, ASTM A-74, latest revision, PVC (polyvinyl-chloride) sewer pipe, ASTM D-3034, latest revision, unglazed clay sewer pipe, ASTM C-261, latest revision, vitrified clay sewer pipe, ASTM C-700, latest revision, or ductile iron pipe, AWWA specification C-151 cement-lined, and shall meet requirements of state plumbing code. Joints shall be as set out hereinafter. Any part of the building sewer that is located within five (5) feet of a water service pipe shall be constructed with cast iron soil pipe or ductile iron pipe, unless the building sewer is at least one foot deeper in the ground than the water service line. In the latter case, vitrified clay pipe may be used. Cast iron soil pipe or ductile iron pipe may be required by the city where the building sewer is exposed to damage or stoppage by tree roots. Cast iron soil pipe or ductile iron pipe shall be used in filled or unstable ground, in areas where the cover over the building sewer is less than three (3) feet, or in areas where the sewer is subject to vehicular or other external loads.
(E) The size, slope, alignment, materials of construction of a building sewer, and the methods to be used in excavating, placing of the pipe, jointing, testing, and backfilling the trench, shall all conform to the requirements of the local and state building and plumbing codes and other applicable rules and regulations of the city.
(F) All costs and expenses incidental to the installation and connection of the building sewer shall be borne by the owner(s). The owner(s) shall indemnify the city for any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer. Fees for connection shall be as established by the city.
(G) The owner shall ensure that all excavations for building sewer installation shall be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, parkways, and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the city.
(H) In all buildings in which any sanitary facility drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by such drain shall be lifted by an approved means and discharged to the same building sewer. Drain pipe and sump for collection of such sanitary drainage shall be above basement floor or in separately watertight or drained sump or channel.
(I) The building sewer shall be connected into the public sewer at the easement or property line. Where no property located service branch is available, an authorized agent of the city shall cut a neat hole into the main line of the public sewer and a suitable wye or tee saddle shall be installed to receive the building sewer. The invert of the building sewer at such point of connection with a saddle shall be in the upper quadrant to the main line of the public sewer. A neat workmanlike connection, not extending past the inner surface of the public sewer, shall be made and the saddle made secure and watertight by encasement in epoxy cement specially prepared for this purpose. A wye and H bend fitting shall be installed at the property line between the public sewer and the building sewer. This fitting shall serve the purpose of a cleanout and for applying the smoke test during inspection of the line. After testing, a cast iron or ductile iron riser will be inserted in this fitting and brought flush with the ground surface. A stopper or plug, outfitted with a type joint applicable to the pipe used, shall seal this riser against the intrusion of ground or surface water.
(J) All building sanitary sewer lines will be installed so as to meet or exceed the most current revision of the state plumbing code.
(K) All persons working on city sewers with a cleaning rod must use an approved type rod in cleaning sewer connections to city sewers.
(Ord. No. 17-91, 6-25-91)
(A) The applicant for the building sewer permit shall notify the superintendent when the building sewer is ready for connection to the public sewer. The connection shall be made under the supervision of the superintendent or his representative. The connections shall be made gastight and watertight and verified by proper testing.
(B) All building sewers shall be smoke tested through the wye branch at the public sewer connection, with public sewer tightly plugged off, after connections at both ends are made and after all pipe is properly bedded and backfilled at least to top of pipe and if backfill is completed, within two weeks after completion of backfill. At time of test, any openings into the building drain inside the building shall be water trapped or plugged. Any leakage of smoke from building sewer or building drain and plumbing shall be located at test and repaired to stand repetitions of smoke test without leakage. When smoke testing is completed, the temporary flow line plug shall be removed and a permanent water tight plug shall be placed in branch of test wye-branch and carefully backfilled by hand and tamped to at least six (6) inches above the top of the branch.
(Ord. No. 17-91, 6-25-91)
All architects, contractors, builders, or other persons who shall hereafter erect new buildings for dwelling, manufacturing or commercial purposes, on a lot or parcel of ground abutting on a street, alley or easement in the city in which there has been installed or may be installed and maintained any sewer line shall, before erecting any building, exhibit to the city council, or any other board or body of the city which may be in charge and control of the municipal sewer system, satisfactory evidence that a means has been or will be provided for connecting the sanitary sewerage drain pipes from the building with the sewer line.
(Ord. No. 9.61, § 2, 5-24-61)
Division 5. Pollutant Discharge Limits
The following described substances, materials, waters or wastes shall be limited in discharges to municipal systems to concentration or quantities which: will not harm either the sewers, wastewater treatment process or equipment, will maintain and protect water quality in the receiving stream, and will not otherwise endanger lives, limb, public property, or constitute a nuisance. The superintendent may set additional limitations or limitations more stringent than those established in the provisions below if in his opinion more severe limitations are necessary to meet the above objectives. In forming his opinion as to the acceptability of a discharge, the superintendent shall give consideration to such factors as the quantity of subject waste in relation to flows and velocities in the sewers, materials of construction of the sewers, the wastewater treatment process employed, capacity of the wastewater treatment plant, and other pertinent factors.
(Ord. No. 17-91, 6-25-91)
(A) Wastewater containing more than twenty five (25) milligrams per liter of petroleum oil, non-biodegradable cutting oils, or products of mineral oil origin.
(B) Wastewater containing floatable oils, fat, or grease, whether emulsified or not, in excess of one hundred (100) milligrams per liter or containing substances which may solidify or become viscous at temperatures 32-150 degrees (0-65 degrees C).
(C) Any garbage that has not been properly shredded. Garbage grinders may be connected to sanitary sewers from homes, motels, institutions, restaurants, hospitals, catering establishments, or similar places where garbage originates from the preparation of food in kitchens for the purpose of consumption on the premises or when served by caterers.
(D) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants which: injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, causes the city to violate the terms of its KPDES permit, prevents the use of acceptable sludge disposal methods, or exceed a limitation set forth in a categorical pretreatment standard.
(E) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the city in compliance with applicable state or federal regulations.
(F) Any water or wastes which by interaction with other water or wastes in the public sewer system release obnoxious gases, from suspended solids which interfere with the collection system, or create a condition deleterious to structures and treatment processes.
(G) Any wastewater with objectionable color which cannot be removed to an acceptable level within the operation of the wastewater treatment process unless otherwise specifically noted in the industrial user permit (IUP).
(H) Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed to the extent required by the city's NPDES/KPDES permit.
(I) Any waste(s) or wastewater(s) classified as a hazardous waste by the Resource Conservation and Recovery Act (RCRA) without a sixty (60) day prior notification of such discharge to the superintendent. This notification must include the name of the hazardous waste, the EPA hazardous waste number, type of discharge, volume/mass of discharge and time of occurrence(s). The superintendent may prohibit or condition the discharge(s) at any time.
(J) (1) Any water or wastes which have characteristics based on a twenty-four (24) hour composite sample, grab or a shorter period composite sample, if more representative, that exceed the following normal maximum domestic wastewater parameter concentrations:
Parameter
|
Maximum Allowable Concentration Without Surcharges
|
BOD | 250 mg/l |
TSS | 250 mg/l |
NH3
-N
|
25 mg/l |
Oil and Grease (total) |
100 mg/l
|
(2) Any person discharging wastewater exceeding the maximum allowable concentration as noted above, will be subject to a surcharge fee for each pound loading over and above the set limit. Any other amenable constituents requiring the addition of specific chemicals for proper treatment will also be subject to surcharge as noted on the industrial user permit. Exceedance of the effluent limits specified above shall not be deemed to constitute a violation of a permit condition or this chapter if the appropriated surcharge fee is paid and the discharge does not cause interference or pass through of the POTW.
(K) The Utility Director and/or his or her designee is authorized to establish local limits pursuant to 40 CFR 403.5(c). In addition, the Utility Director may require the development of best management practices (BMPs), by ordinance or in individual wastewater discharge permits, to implement local limits and the requirements of this chapter. Such BMPs shall be considered local limits and pretreatment standards. The following limitations are established for characteristics of any wastewaters to be discharged into the municipal sewer system subject to any compliance schedule as established in the industrial user permit. All significant industrial users must comply with these limitations where they are more stringent than applicable state and/or federal regulations.
