13.16.105: REPAIRS OR EXTENSION OF PRIVATE SEWER:
   A.   When any private sewer, including the service connection or tap, becomes obstructed, broken or out of order, the owner, agent or tenant of such premises shall repair same at the owner's expense. The expense to the owner shall also include the replacement of street, curb and gutter, sidewalk or any other public improvement disturbed by the repair of any private sewer, including the service connection or tap. No person shall construct, relay, repair or extend any private sewer, including the service connection or tap, until the person doing the same obtains a private sewer permit from the City Building Department.
   B.   It is unlawful for any person to extend any private sewer beyond the limits of the building or property for which a permit has been given without obtaining an additional permit for the desired extension. The existence of a private sewer permit shall in no way be construed as making permissible any work for which an excavation permit may be required as set forth in this Code.
   C.   Any replacement of sanitary sewer piping serving any and all fixtures which have flood level rim located below the elevation of the next upstream manhole cover of any public or private sewer shall be protected from backflow of sewage by installing an approved type of full house backwater valve.
