No person shall construct, improve, or repair a sewerage connection, or lateral line, to the city sanitary sewer collection service lines unless such person shall install a backflow preventer or flap valve in line with the lateral or connection such that flows from the sewer collection system cannot flow from the collection system into any structure or building. Any person operating a new or existing sewer collection line from a structure without a backflow prevention system approved by the city shall be deemed to have expressly waived any claim of liability on the part of the city, its officers, agents, and employees, in the event wastewater flows from the wastewater collection lines of the city into or on the property serviced by city sewer wastewater collection lines. The city shall provide existing customers serviced by city sewer collection system, an approved backflow prevention device without charge upon application to the Safety and Service Director.
