(A) Requirements For Extension Of Existing Mains. If the public sanitary sewer system is within six hundred (600) feet of the proposed subdivision or development, and said system has the available capacity, the Subdivider/Developer shall extend the existing system and sewer to his entire proposed development at his own expense.
(1) Should the public sanitary sewer system be more than six hundred (600) feet away from the proposed subdivision or development, the Village may negotiate with the Subdivider/Developer to share the cost of extending the existing system and sewer.
(B) Construction Plans.
