The application for and written permission to make a connection to a public sewer shall specify the permissible use of such connection and such specifications shall be governed by the following requirements:
(a) Waste Discharge. Sewage, including wastes from water closets, urinals, lavatories, sinks, bathtubs, showers, laundries, cellar floor drains, bars, soda fountains, cuspidors, refrigerator drips, drinking fountains, stable floor drains and other objectionable wastes shall be discharged into a sanitary or combined sewer, and in no case into a storm water sewer.
(b) Garage Wastes. All structures used for housing, sale, repair, greasing or washing automobiles, trucks and tractors shall be provided with proper means for draining the floors and repair pits in such manner that no drainage therefrom shall flow over any street, alley or paved approach. Garage drains shall be so arranged as to intercept all oil, gasoline or other inflammable fluids, as well as sand, silt and other solids for the purpose of excluding them from the sewerage system. Such drains shall have the accumulated oils and other inflammable fluids pumped or otherwise removed therefrom at regular intervals, and shall be maintained so as to insure the exclusion of the same from the sewerage system.
Garage drains shall be kept free of sand, silt and other solids and shall be subject to a periodical inspection. They shall be so constructed as to have a sand receptor of not less than twelve inches in depth and diameter below the bottom of the outlet, a seal depth and diameter of not less than twelve inches in the drain with an outlet therefrom of not less than four inches; a ventilating chamber of not less than twelve inches in depth and diameter with a sealed inlet opening not less than four inches in diameter; and a ventilating pipe leading from the ventilating chamber of not less than three inches in diameter, and carried up above the highest part of the roof and subject to the same conditions as for roof outlets of soil and waste pipes.
Capacity for the sand receptor is based on a storage capacity of four automobiles and a proportionate cubical capacity must be added for each additional automobile storage capacity with corresponding diameter of the drain carried to the floor line.
Every existing building or one hereafter constructed or converted into a place of business where oil, gasoline, benzine, naptha or other inflammable oils or compounds used, shall be provided with a special drain the same as that specified herein.
(c) Detrimental Wastes. Waste shall not be discharged into a storm water sewer but may be discharged into a sanitary sewer if such waste is of such character so as not to be detrimental to the sewerage system, or to the sewage treatment works to be determined by the Plumbing Inspector.
(d) Surface Water. Surface water, rain water from roofs, subsoil drainage, building foundation drainage, cistern overflow, clean water from condensors, waste water from water motors and elevators, and any other clean and unobjectionable waste water must be discharged into a storm or combined sewer when available and in no case into a sanitary sewer.
(e) Kitchen Wastes. Kitchen or other greasy wastes from hotels, restaurants, club houses, public institutions or other establishments in which much cooking is done or greasy wastes collected, shall be intercepted by a catch basin or a grease trap, and then conducted to the house sewer.
