468.14.1. If the management board decides to use moneys from the general fund to pay a capital expenditure incurred for the benefit of only some of the municipalities in whose territory the board has jurisdiction, it may decide to reimburse the fund by means of an aliquot share payable by the municipalities concerned.
In such a case, the management board shall authorize the use of the moneys by a by-law that specifies the amount of the moneys used and contains a detailed description of the expenditure. The by-law must also specify the term of repayment, which is not to exceed the useful life of the property that the moneys enable the board to acquire, repair, restore or build, and must require an aliquot share from the municipalities for whose benefit the expenditure is incurred.
