About Your Bill

Water and Sewer charges are billed by the District monthly.  All water and sewer bills are the responsibility of the property owner and remain their responsibility until the District is notified of a change in ownership of the property.

Bills are due and payable upon receipt.  Accounts become delinquent if not paid 30 days after the billing date.

Delinquent accounts not paid by 4:00 p.m. on the 5th day of the following month will be charged a late fee of 1.5%  on any unpaid balance.

Delinquent accounts not paid by 4:00 p.m. on the 15th day of the following month will be charged a delinquent fee of $20.00 on any unpaid balance.

If you have questions regarding your bill please contact the office at 530-533-0740.
