Where public sanitary sewage systems are not within 5,280 feet the city may allow one of the following alternatives:
A. Central sewage system, the maintenance cost to be assessed against each property benefitted. Where plans for future public sanitary sewage systems exist, the applicant shall install the sewer lines, laterals and mains to be in permanent conformance with such plans and ready for connection to the public sewer mains; or
B. Individual disposal systems, provided the applicant shall install sanitary sewer lines, laterals and mains from the street curb to a point in the subdivision boundary where a future connection with the public sewer main shall be made. Sewer lines shall be laid from the house to the street line, and a connection shall be made available in the home to connect from the individual disposal system to the sewer system when the public sewers become available. Such sewer systems shall be capped until ready for use and shall conform to all plans for installation of the public sewer system, where such exist, and shall be ready for connection to the public sewer main.
