N.J. Stat. § 40:14B-61
No sewage disposal plant or other facilities for the collection, treatment or disposal of sewage arising within a district shall be constructed unless the municipal authority shall give its consent thereto and approve the plans and specifications therefor. No facilities for the distribution of water within a district shall be constructed unless the municipal authority shall give its consent thereto and approve the plans and specifications therefor. Each municipal authority is hereby empowered to give any such consent and approval, subject, however, to the terms and provisions of any agreement with the holders of bonds. Upon submission to the authority of a complete application for approval of such a plant or facilities, the authority shall approve or disapprove the application within 90 days of the date of its submission, but the authority may extend the time for a period not to exceed 30 days by adoption of a resolution therefor. As used in this section, "complete application" means an application form completed as specified by resolution and the rules and regulations of the authority, and the accompanying documents, plans and specifications required by resolution for approval of the plant or facilities. An application shall be certified as complete, for the purposes of the commencement of the time for action by the authority, immediately upon the meeting of the requirements specified in the resolution and the rules and regulations of the authority. Failure of a municipal authority to approve or disapprove plans and specifications submitted pursuant to this section within such time, shall constitute approval thereof and consent of the authority to construction of the plant or facilities.
