Whenever any private sewer pipe connected with any public sewer becomes obstructed, broken or out of order, and if the owner, agent or occupant of such premises fails to repair the same within five days after notification to do so by the superintendent, the superintendent is authorized to remove, reconstruct, replace, alter or clear the same as required, at the expense of the owner, agent or occupant of such premises, and when two or more houses or buildings are connected with the same private sewer, the owners, agent or occupants of such premises, shall be jointly and equally liable for any work done at the direction of the superintendent under this section. No permit shall be required for the removal of obstructions from private sewers, providing the pipe is not damaged. (Ord. 209 § 10, 1974).
