Yes. However, if you are out of town during the winter months you may be eligible for an adjustment. Please contact Johnson County Wastewater. Your account will be reviewed and any appropriate adjustments will be made. The minimum user charge for months you are gone is an amount that is at least equal to the Customer Service Charge. For months that you actually reside in your home, you will be charged the default value user charge. The default is based on the average residential winter water use for all residential customers. The default user charge is used when the average winter water use appears to be an inaccurate measure of average use, or a customer does not have actual winter water use.
