Article XI — Backflow And Cleanout Installation

All new building laterals including lateral replacements shall be equipped with a cleanout riser. All new building laterals shall be also fitted with a backflow prevention device of type and materials as approved by the City. In addition, existing buildings in which the elevation of the lowest floor is less than 12 inches above the rim elevation of the nearest upstream manhole or junction structure in the reach of a City main sewer into which a building sewer, through a lateral, connects shall be protected from backflow of sewage by installing a backflow protective device of a type and in the manner prescribed by the City. Any such backflow protective device shall be installed by the owner of the property on which the building is constructed, and shall be located on the building sewer between the building and the property line, preferably at the location of the cleanout. The backflow protective device, if below grade, shall be enclosed in a suitable concrete utility box with removable cover and shall be readily accessible for inspection and maintenance. The installation of any such backflow protective device shall be at the sole cost and expense of the property owner. The maintenance of the backflow protective device shall be the sole obligation of the owner or the owner's successor in interest. The City shall be under no obligation to ascertain that the backflow protective device continues in operating condition. (Ord. 286, 2012; Ord. 322 § 1, 2014)
