Johnson County Wastewater receives national recognition
September 1, 2015

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 Providence, RI for its outstanding compliance records in the 2014 calendar year and was presented with two Platinum Awards. In total, JCW earned six Peak Performance awards.

JCW received two Platinum Peak Performance Awards to honor treatment works that have completed at least five years of 100% complete and consistent National Pollutant Discharge Elimination System (NPDES) permit compliance.

The county’s Platinum Award recipients are:

  • The Mill Creek Regional Plant at 20001 West 47th Street in Shawnee for eight years of permit compliance, and
  • The Blue River Main Plant at 2523 West 151st Street in Overland Park for nine years of permit compliance.

Three JCW treatment facilities received the Gold Peak Performance Award which honors treatment works that have achieved 100% compliance with the NPDES permit for 2014.

The Gold Peak Performance Award honorees are:

  • Douglas L. Smith Middle Basin Plant
  • New Century AirCenter Plant
  • Tomahawk Creek Plant

One treatment facility earned a Silver Peak Performance Award which recognize facilities that received no more than five NPDES permit violations in 2014.

Silver Peak Performance Award honoree is:

  • Myron K. Nelson Plant

 In 2014, Johnson County Wastewater had a 99.7 percent compliance rate with regard to NPDES discharge violations. Of a possible 2,237 violations, the department recorded seven violations for the year.

 “It is very difficult to achieve that level of compliance,” said John O’Neil, general manager for Johnson County Wastewater.

Cooking Involves Disposal of Grease and Oil
March 5, 2015

If you're like most people, the disposal of grease and oil left over from the turkey fryer and other cooking adventures is simple - down the drain or the toilet, right? Actually, that's the worst thing you can do. The grease and oil will solidify in your sewer pipes and can cause some nasty problems. The grease team at Johnson County Wastewater suggests the following:

The oil can be used several times if you filter out the solids.  Once the oil is a mixture of teriyaki and Cajun you can either take it to the HHW site for disposal or many restaurants will take the oil if they have a dumpster for it because they will get paid for it.

Otherwise, you should put it in a container after it’s cool and dispose of it in the trash.

Happy cooking!
