N.J. Stat. § 40:14B-44
In the event that a sewer service charge of any municipal authority with regard to any parcel of real property shall not be paid as and when due, the municipal authority may, in accordance with section 57 of this act, cause the supply of water to such parcel by any county, municipality or other person to be stopped or restricted until such sewer service charge and any subsequent sewer service charge with regard to such parcel and all interest accrued thereon shall be fully paid to the municipal authority. If for any reason such supply of water shall not be promptly stopped or restricted as required by section 57 of this act, the municipal authority may itself shut off or restrict such supply and, for that purpose, may enter on any lands, waters or premises of any county, municipality or other person. Such supply of water to such parcel shall, notwithstanding the provisions of this section, be restored or increased if the State Department of Health, upon application of the local board of health or health officer of the municipality where such parcel is situate, shall after public hearing find and shall certify to the municipal authority that the continuance of such stopping or restriction of such supply of water endangers the health of the public in such municipality.
