Cash payments can be made at the kiosk, but no change will be given. The change will be a credit on your account. To drop off a water payment in the kiosk drop box, please enclose it in an envelope and write your account number or service address on your check. No late fees will be charged.

All meters are read electronically on the 15th and utility bills are mailed on the last day of the month. 

Payment is due to our office on or before the 16th of each month (we do not consider postmark on mailed items). Penalty is assessed on the 17th and a late notice is mailed to all outstanding accounts. This notice serves as a cut-off notice and must be paid by the end of the month to avoid service disconnection and a $50 disconnect/reconnect fee.
