Department News

Mother Earth's Day is April 22

People all over the world recognize April 22 as Earth Day, an opportunity to appreciate and generate awareness about the natural environment. Here, at Johnson County, we strive to do our part to make sure our county and planet are healthy for years to come. From building facilities designed to last for more than 100 years, to reducing our energy costs, managing our storm water and treating our wastewater, we're building a community that's better for the environment.

Johnson County - a community of choice for generations to come. 

A Reminder to Our Customers: Be Aware and Be Safe.

Always ask for proper identification before allowing someone inside your home to do any kind of repair or utility work. Residents should look for company identification, uniforms bearing the company name and work vehicles with company logos and markings. The Johnson County Wastewater logo is on all employee ID cards, uniforms, and vehicles. Contact the utility company in question before allowing an individual into your home. Confirmation for JCW employees can be made by calling Customer Service at 913-715-8590.

Something else you should be keenly aware of are the phone scammers. This is a warning message that the Board of Public Utilities recently released.

If you feel your safety is threatened, or you are doubtful, don’t guess; call 9-1-1.

Commercial Customers May Save Money in Voluntary Program

Johnson County Wastewater's commercial customers may participate in a voluntary program to obtain credit for water which does not enter the department's collection system. In order to receive credit, Johnson County Wastewater requires that this water be continuously metered via a deduct meter. A deduct water meter measures the amount of water not discharging into the sanitary sewer system. This would include water used for lawn sprinkler systems or cooling towers. Here is additional information about the Sewer Use Credit Program.

Changes to JCW Sewer Connection Fee

Effective Jan 1, 2014, sewer connection fees are no longer based on Equivalent Dwelling Units (EDUs) calculated by square footage and business activity type. Instead, the fees are based on the water meter size for each building or space as issued by the water utility (e.g. WaterOne, City of Olathe, BPU, et al).

Why the change? This change in methodology was approved on March 15, 2012, by the Johnson County Board of Commissioners and makes Johnson County Wastewater's policy consistent with industry best practices and standards.

How does this change affect me? The policy affects information required for residential permit issuance and the order of submissions during the commercial permit application process. In addition for commercial permit projects, the modified use fee portion of permits associated with tenant finish or building addition projects no longer apply.

The Johnson County Wastewater connection fee schedule does apply and customers are required to obtain a sewer connection permit for all new water meters or when a water meter size increases. Fees are due to Johnson County Wastewater at the time the meter or meter size change permit is issued by the water utility. Fees for meter size increases will be calculated as the difference in fee between the existing meter and the new meter. The $200 Johnson County Wastewater permit fee, the $400 commercial review fee, additional special inspection fees, and/or grease permit fees remain for permits, as applicable.

Connection Fees: The 2014 connection fee schedule by meter size is as follows. This schedule does not include the $200 permit fee, special inspection fees, or grease permit fees.

Please see the Residential and Commercial permitting pages for additional permitting information.

Billing Change for JCW Customers in 2014

In January 2014, Johnson County Wastewater completed a multi-year conversion of its billing method to a unified rate model. This means that the current wastewater bills look similar to other utility bills such as water, gas, and electric and is now in line with industry best practices. The current Johnson County Wastewater charge reflects both the costs to operate its system and to invest/reinvest in the capital improvements necessary to operate the system. 

In 2013, the capital cost was a uniform rate; all single family residences were charged the same capital amount, regardless of the impact they had on the system.  This charge appeared as Capital Charge (EDU) on the bimonthly bill and was $24.76 bimonthly. Prior to 2013, this charge appeared as a line item titled WASTEWTR CAP on the real estate tax statement. 

Under the unified rate model, both operation and capital charges are based on a fixed Service Charge to provide customer service, and a variable Volume Charge based on the volume of water used and discharged to the sanitary sewer system for treatment.

In 2014, Johnson County Wastewater implemented an overall revenue requirement (expenses) increase of 6.5 percent. The amount customers are billed varies from one customer to the next as it is based on their Average Winter Water Usage (AWWU). Those who have a greater impact on the sanitary sewer system will now pay more than those who contribute less. The following table demonstrates how the components of the wastewater bill changed from 2013 to 2014:

2013 Charges:

  • Service Charge (SC):
    • Operations portion of SC = $5.40
    • Capital portion of SC = $0.00
  • Volume Charge:
    • Operations portion of vol. charge = $2.67/1,000 gallons ($0.00267 per gal.)
    • Capital portion of vol. charge = $0.00
  • Capital Charge:
    • EDU fixed capital charge = $148  ($24.67 per bi-monthly bill)   

2014 Charges:

  • Service Charge (SC):
    • O&M portion of SC = $6.33
    • Capital portion of SC= $5.73
  • Volume Charge:
    • O&M portion of vol. charge = $3.27/1,000 gallons ($0.00327 per gal.)
    • Capital portion of vol. charge = $2.24/1,000 gallons ($0.00224 per gal.)

(Please note that Johnson County does not provide tax advice to its customers regarding the deductibility or non-deductibility of its utility charges for federal or state income tax purposes, and advises customers to consult their CPA or other tax professional regarding proper treatment of such charges.)
