N.J. Stat. § 58:14-34.7
Whenever any contracting agency is using said intercepting sewer in excess of its allotted capacity, the commissioners may, in addition to the right to restrain such excess use, by application to the court having jurisdiction over the same, in their judgment, permit such excess use whenever they ascertain and determine that such excess use will not interfere with the use of said intercepting sewer to the extent of its allotted capacity by any other contracting agency, and that the capacity of said intercepting sewer is sufficient to carry such excess, permit such contracting agency to continue to use said intercepting sewer for such excess and charge the municipality using such excess at an annual rental at the rate of fifteen hundred dollars ($1,500.00) annually per million gallons of average daily flow, in addition to its proportionate share of the annual costs of maintenance, repairs and operation of the intercepting sewer with respect to its total discharge of sewage into such intercepting sewer. The said rental collected by the commissioners shall be disbursed by the commissioners to the contracting agencies in the same manner as provided herein for the disbursement and distribution of the rentals arising from leases between the commissioners and lessees.
