The legislative body of each member municipality shall draw an order on the municipal treasury for the amount of such assessment and the municipal Treasurer shall pay to the District Treasurer the amount of such order in accordance with the schedule for payments adopted by the Board of Supervisors. If any member municipality shall fail to pay when due any assessment against it by the District, it shall incur the maximum penalty allowed by law plus interest at the maximum rate allowed by law.
