A plat or replat or site development permit will not be approved unless the proposed lot(s) or site developments are served by an approved means of wastewater collection and treatment. The projected wastewater discharge of a proposed development shall not exceed the proposed capacity of the proposed development’s wastewater system. The City may require the phasing of development and/or improvements to the systems so as to maintain adequate wastewater capacity. New developments or improvements of existing developments should consult the City of Liberty Hill or appropriate wastewater utility service provider for compliance.
