How to Pay Your Water and Sewer Bill
Payments are due upon presentation of your monthly billing statement each month. If not paid by the last business day of the month, the bill will be delinquent. If delinquent, a Notice of Intention to Disconnect Service will be mailed, stating the amount due, including a late notice charge (of 10%). You will have fifteen days to pay the bill, or the water service will be disconnected.
To avoid a late charge, your payment is due by the last business day of the month that your billing statement is received. Please be advised that the front office is closed on Fridays and therefore is not considered a business day. Payments received after 4:00 p.m. will be posted the following business day. Postmarks are not accepted.
