The city assumes no responsibility for the maintenance of any building sewer lines on private property or in easements or street rights-of-way. The owner of property served by a building sewer is responsible for the building sewer's connection to the public sewer, and for the entire length of the building sewer from the public sewer to the building the line serves. Each property owner shall, at the property owner's sole expense, operate, maintain, and repair and/or replace the building sewer so that it does not cause or contribute to an obstruction in the public sewer. The owner shall perform such duties as may be required in response to notice from the city of observed obstructions in the public sewer attributable to the building sewer's condition. Where such maintenance requires excavation or replacement of existing sewer facilities, the owner shall apply for and receive appropriate permits from the city.
If one or more discharges from a building sewer result in damage, partial or complete blockage, impairment of the public sewer's conveyance capacity, or excessive city maintenance of the public sewer, the discharger responsible shall be liable for said damage, and shall take the corrective action necessary to restore the public sewer system to full and normal operations. "Excessive maintenance" of the public sewer means pipe flushing or cleaning required more frequently than once every 12 months. Liability under this section is in addition to civil penalties imposed pursuant to Chapter
17.64 RMC.
