10. The person in charge may collect a tax, a fee or a charge from the persons served by his or her waterworks or sewer system.
In order to set the rate to be collected, the person in charge must calculate the sum of the expenses incurred in the preceding year of operation. The person in charge then sets a rate corresponding to the proportion of the sum of the expenses paid by each person served by the system, which are apportioned in accordance with Division IV.
In the case of a new waterworks or sewer system, a rate may be set for the first year of operation. In that case, the rate is set according to the sum of the expenses incurred for the installation of the system.
