Don't invite your plumber over for holiday dinner
November 22, 2017

You might want to think twice about pouring any fats, oils or grease (FOG) down the drain as you’re preparing your meals. Rinsing that stuff down the drain can cause you some serious problems because they generally solidify at room temperature. So you pour it down the drain, it hits a cold spot in your pipe system and guess what – you’ve just created the beginnings of a clog.

Over time, if you and your neighbors continue to dispose of grease in this manner, the sewer pipe will likely become completely blocked and guess what – the sewage flow will back up and come out at the lowest access point in your home creating, at the very least, an unsanitary and dangerous situation.

So, now you know what not to do – here’s what to do instead!

  • Pour excess cooking grease into a can instead of down the drain. When the can is full, allow it to solidify at room temperature and then simply throw it in the trash.
  • Scrape greasy plates and food scraps into the trash and use a paper towel to capture sauces and drippings that are full of fat and oil, instead of rinsing them down the kitchen sink.
  • Remember, fats and oils can be in just about anything, including condiments, salad dressings and gravy.

Happy cooking and don’t ruin your holiday by having to call in a plumber. They don’t typically give Black Friday discounts!

JCW plants all achieve 100% permit compliance in 2016
August 30, 2017

Each year the National Association of Clean Water Agencies (NACWA) recognizes public wastewater facilities for outstanding compliance with National Pollutant Discharge Elimination System (NPDES) permit limits. This recognition program consists of Peak Performance Awards in three categories - Platinum, Gold and Silver.

Johnson County Wastewater was recognized in July at the NACWA national conference held in St. Louis for its outstanding compliance records in the 2016 calendar year.

Two JCW treatment facilities received the Gold Peak Performance Award which honors treatment works that have achieved 100 percent compliance with the NPDES permit for 2016.

  • The Myron K. Nelson Plant
  • The Douglas L. Smith Middle Basin Plant

This year, JCW is proud to announce they received four Platinum Peak Performance Awards to honor treatment works that have completed at least five years of complete and consistent National Pollutant Discharge Elimination System (NPDES) permit compliance. This is the highest number of Platinum Awards the department has ever earned. The county's Platinum Award recipients are:

  • The New Century AirCenter and the Tomahawk Creek plants for five years of permit compliance, 
  • The Mill Creek Regional Plant for ten years of permit compliance, and
  • The Blue River Main Plant for eleven years of permit compliance. 

Staff members were recognized at the regular meeting of the Johnson County Board of County Commissioners last Thursday.

Platinum Awardees were featured in a video presentation at an awards ceremony during NACWA's 2017 Summer Conference, and in the video, facility staff were asked to "jump" for clean water - with a prize at stake for best photo. 

General Manager Susan Pekarek has high praise for the employees. "All of you are very humble. You are committed to keeping public health and the environment safe. You do what it takes, not only operating and maintaining our systems during the day, but also coming in to work in the middle of the night, on weekends and holidays. You don't brag on yourselves; you simply do what you are committed to do. And nearly all the time, you do it without anyone in the public knowing how you are taking care to protect them. For that, I thank you. Keep up the great work. The rest of the leadership team and I are so very proud of all you!"  

Better flood protection available

In the past, some Johnson County homeowners have faced the frustrating challenge of basement flooding during extremely heavy rains. There are several common causes for wet basements. Because Johnson County Wastewater wants to help you better protect your home during these rains, a Backup Prevention Program is available to homeowners. This program is voluntary and provides funding to eligible homeowners so they may install a backup prevention device or make plumbing modifications on their property.

For details about this program and whether you might be eligible, go to Johnson County Wastewater Backup Prevention Program.

Smith Middle Basin Wastewater Treatment Facility (Lower Indian Creek), and the Dykes Branch sub-watershed. Johnson County Wastewater is expanding the facility to 19 Million Gallons per Day (MGD). It currently treats 7 (MGD). Black & Veatch/HDR engineering team recently completed the Project Definition Phase of the expansion and McCarthy has been hired as the Construction Manager at Risk (CMAR) for the project.

Construction Schedule: The Tomahawk project is scheduled to start in 2018 with completion in 2021.

Subcontractors are needed in these areas.

Public Health Advisory Lifted For Water in Brush Creek
May 17, 2017

In collaboration with Johnson County Wastewater, the Johnson County Department of Health and Environment has lifted a health advisory for residents living in the area between 55th and Mission and 75thand Mission. The advisory was issued Saturday, May 13 due to a sanitary sewer overflow into Brush Creek in the areas of Prairie Village and Mission Hills.

Johnson County Wastewater crews investigated the source and determined a private contractor unknowingly drilled into a sewer line in the area near Tomahawk Road and Mission Road.  The damaged line has been repaired. The Wastewater Department flushed the creek in the area and tested the water.  Bacteria levels have returned to normal allowing the advisory to be lifted today.  

If you have questions about the advisory being lifted, please call 913-477-8436.
