N.J. Stat. § 40:62-107.1
In any municipality which has, prior to March twenty-fifth, one thousand nine hundred and thirty-five, owned a water distribution system which has been operated at a loss, and the governing body of such municipality has determined that it is to the best interests of the municipality to sell such system to a commission furnishing water to residents of the municipality, even though the price at which such system may be sold is less than the cost to such municipality of the construction of such system, and where the sale of such system results in a deficit, the municipality may be resolution direct that at least one-twentieth of the amount of the deficit shall be included in the budget or tax ordinance or tax levy for the year succeeding that in which such sale is made and each year thereafter.
