2025 Billing for Service

For 2025, charges for a single-family unit are $37.50 a quarter, or $150 per year.

​Bills are sent out four times a year - January, April, July and October.  If a property owner chooses to pay more than one quarter, they should figure the per unit cost and multiply it by the number of quarters they wish to pay.  The payment will then be posted, and they will not be billed again until all of the payment has been applied.

Please note that the District does not mail statements when an account posts a credit balance.

Accepted Methods of Payment

The District accepts check or money order via mail, and check, money order, or cash in the office. The District encourages customers to use electronic payment methods and email billing to reduce administrative costs.
