About your Bill

Water and Sewer services are billed by the District monthly.  Bills are due and payable upon receipt.  Accounts become delinquent if not paid 30 days after the billing date.

Delinquent accounts will be charged (on the unpaid balance):

• A Late fee of 1-1/2%  on the 5th day of the following month at 4:00pm.
• A Delinquent fee of $20.00 on the 15th day of the following month at 4:00pm.
