I leave my home for the winter. Must I pay a wastewater bill?

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.

I just moved into a new house. How will my “average winter water use” be determined?

New customers moving from outside Johnson County Wastewater’s service area will be assigned a default value user charge that is equal to the average winter water use for all residential customers. If new customers provide Johnson County Wastewater with their previous account information, Johnson County Wastewater will calculate an appropriate average winter water use using the information provided. Johnson County Wastewater customers who move within the sanitary sewer district may request to transfer the average winter water use from their previous address.


What if I have a swimming pool, will I have to pay for filling my pool?

Winter water usage is used in the wastewater bill calculation to avoid charging for usual heavier summer uses such as watering your lawn and garden, washing your car, or filling your swimming pool. If you don’t fill your swimming pool during the winter months, it won’t affect your water usage information for your wastewater bill. All of these water uses do not impact the wastewater treatment system.

Which months will Johnson County Wastewater use to calculate my winter water usage?

The customer's average winter water use will be based on four of the six months between November and April, depending on the customer's billing cycle.

What is the average winter water use (AWWU)?

This is your average water usage during winter months based on meter readings. This is the best measure of the volume of drinkable water used at the property during the winter months that reasonably estimates the volume of wastewater discharged to the wastewater treatment facilities of Johnson County Wastewater. By using winter water usage, Johnson County Wastewater can accurately estimate the volume of wastewater discharged into the treatment facilities by each property.

What is the Customer Service Charge for?

The Customer Service Charge recovers all administrative costs associated with an ongoing billing and collections system. All user classes are charged this fee.

How are my sewer charges calculated?

Residential charges are determined by multiplying the annual volume of average winter water usage by the rate and adding the customer service charge [(Volume x Rate) + customer service charge = Amount]. This amount will be divided by 12 calendar months, which will give you your monthly charge. Since residential customers are billed bimonthly, your bill has two months' worth of wastewater charges.
