Our billing policy is such that the bills are mailed on the last working day of each month. Your payment is credited to your account on the day we receive it. If your payment is not received on or before the due date, which is the 20th day of the month, a 1-1/2% penalty is added to any unpaid balance. If a customer does not receive a monthly bill, or if it reaches him late, he is still responsible for the monthly payment. If within the first week of the month you should not receive a bill, please do not hesitate to contact the District office.
