Quarterly Usage Invoice   

The County invoices each customer for water and sewage usage on a quarterly basis. This bill is generally based on the amount of water used by the property. Usage bills pay the cost of the daily operation and maintenance of the water and sewer system in the County and are increased annually by the CPI. Each customer has 30 days for payment. After 30 days a 5% late fee is added to the bill as required by the County Code Section 256-19(A)(4). Service may be terminated if the bill remains unpaid. If service is terminated an additional fee of $50 will be added to the bill for turn-off/turn-on.  

Annual Assessment Invoice  

Depending on where the property is located within the County, a property served by the County's water and sewer system can have one or more annual assessments that are due on the property. Most annual assessments are mailed July 1 to the latest property owner on record. These assessments are due by September 30 of each year.  The annual assessment includes capital charges, which can vary from property to property depending on the time period of connection and location within the County. These charges are used to pay for the cost of construction transmission facilities, pumping stations, water booster stations, storage facilities, treatment facilities, etc.
