(a) Basic Design Data.
(1) Quantity of sewage. The quantity of domestic sewage flow to be provided for in a separate system of sanitary sewers shall not be less than the following:
A. | Lateral | 350 g.p.c.d. |

C. | Trunk | 250 g.p.c.d. |
(2) Depth. The depth for sanitary sewers shall be as required for the type of building structure and the elevation of the basement to be served. If a basement drain is to be served, the depth of the main sewer below the established grade of the street shall be sufficient to:
A. Enable a house lateral laid on a minimum of two percent slope to have a depth of seven feet at the curb line, measured from the curb grade to the flow line;
B. Provide not less than three feet between the basement elevation and the hydraulic gradient at the main sewer; and
(Ord. 850. Passed 7-1-63.)
C. Provide a minimum of three feet of earth cover above the sewer and under the street pavement. (Ord. 74-42. Passed 5-6-74.)

The sanitary sewer system shall comply with the City Standards for Sanitary Sewer Details, the State of Ohio, Department of Transportation, Construction and Material Specifications, January 1, 1975 edition, as amended, and the Division of Highways, Bureau of Roadway Design, Standard Construction Drawing, as amended by Council, except where they specifically deviate from other ordinances duly enacted by the City.
