When blockages or stoppages occur in a sanitary sewer, there exists the potential for adverse public and private health impacts, bodily injuries and damages to property resulting from sewage overflow and back flooding on public and private property. It is the purpose of this Ordinance to protect the health, safety and welfare of residents of the city and to minimize the possibility of damage to property or injury to persons by requiring the proper installation and maintenance of back water overflow prevention devices pursuant to the directives and standards of the city. The city will not be liable for damage resulting from sewer overflows when a backflow protection device has not been installed or maintained as required by this Ordinance. (Ord. 13-03, 2013)
