The main drainage system of every house or building shall be separately and independently connected with the street sewer, where such sewer exists, except where two houses are built together on a lot with a frontage of 30 feet or less, when one connection with main sewer will be allowed; but there shall be a separate house drain for each house, connected by a Y connection in the front of such houses, at the property line, with main house sewer; or, where one building exists or is erected in the rear of another, on an interior lot, of single ownership, and no private sewer is available, or can be made for the rear building through an adjoining alley, courtyard or driveway, the house drain from the front building may be extended to the rear buildings, and the whole will be considered as one house or building drain. Where it is necessary to construct a private sewer to connect with sewer on adjacent street, such plans may be used as may be approved by the Building and Housing Inspector, but in no case shall joint drains be laid in cellars, parallel with the street or alley.
