§ 53.061 BUILDING SEWERS; PERMITS; FEE; RESPONSIBILITY; AND THE LIKE.

   (A)   (1)   (a)   There shall be two classes of building sewer permits:

            1.   For residential and commercial service; and

            2.   For service to establishments producing industrial wastes.

         (b)   In either case, the owner or his or her agent shall make application on a special form furnished by the City Council. The permit application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the City Council. The industry, as a condition of permit authorization, must provide information describing its wastewater constituents, characteristics and type of activity.

      (2)   A building sewer permit will only be issued and a sewer connection shall only be allowed if it can be demonstrated that the downstream sewerage facilities, including sewers, pump stations and wastewater treatment facilities, have sufficient reserve capacity to adequately and efficiently handle the additional anticipated waste load.

(Prior Code, § 23-27)

   (B)   No premises shall be connected with the sanitary sewer system of the city, except upon the payment of a connection charge as determined by resolution of the City Council. The connection charge shall be paid to the City Administrator at the time when application for a permit to connect with the sanitary sewer system is made. The connection charge shall be returned to the applicant should the application be refused.

(Prior Code, § 23-28)

   (C)   All costs and expenses incident to the installation and connection of the building sewer shall be borne by the owner. The owner shall indemnify the city from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer.

(Prior Code, § 23-29)

   (D)   A separate and independent building sewer shall be provided for every building.

(Prior Code, § 23-30)

   (E)   Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the city, to meet all requirements of this subchapter.

(Prior Code, § 23-31)

   (F)   (1)   All sewer construction shall conform to the State Plumbing Code.

      (2)   Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by the building drain shall be lifted by a means which is approved in accordance with division (F)(1) above and discharged to the building sewer.

      (3)   No person shall make connection of roof downspouts, exterior foundation drains, areaway drains or other sources of surface runoff or ground water to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sewer.

      (4)   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.

(Prior Code, § 23-32)

   (G)   All building drains which have backup problems shall have a backwater valve installed at the owner's expense and it shall be the owner's responsibility to see that the backwater valve is kept clean and workable. The city will assume no liability for any damages resulting from backup.

§ 53.062 PROHIBITED DISCHARGES.

   (A)   (1)   No person shall discharge, or cause to be discharged, any storm water, surface water, ground water, roof runoff, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters to any sanitary sewer.

      (2)   Storm water and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers or to a natural outlet approved by the city. Industrial cooling water or unpolluted process waters may be discharged, on approval of the city, to a storm sewer or natural outlet.

   (B)   No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:

      (1)   Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas;

      (2)   Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance, or create any hazard in the receiving waters of the sewage treatment plant;

      (3)   Any waters or wastes having a pH lower than 5.5 or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works; and/or

      (4)   Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewage works such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers and the like, either whole or ground by garbage grinders.

   (C)   No person shall discharge or cause to be discharged the following described substances, materials, waters or wastes if it appears likely in the opinion of the city that the wastes can harm either the sewers, sewage treatment process or equipment; have an adverse effect on the receiving stream; or can otherwise endanger life, limb or public property or constitute a nuisance. In forming the opinion as to acceptability of these wastes, the city will give consideration to the factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant and maximum limits established by regulatory agencies. The substances prohibited are:

      (1)   Any liquid or vapor having a temperature higher than 150°F (65°C);

      (2)   Any waters or wastes containing toxic or poisonous materials; or oils, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between 32° and 150°F (0° and 65°C);

      (3)   Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths horsepower or greater shall be subject to the review and approval of the city;

      (4)   Any waters or wastes containing strong, acid, iron pickling wastes or concentrated plating solutions whether neutralized or not;

         (a)   Reject the wastes;

         (b)   Require pretreatment to an acceptable condition for discharge to the public sewers;

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