Public involvement and education activities related to public acceptance and support of 
beneficial biosolids use 

KUB achieved Platinum level certification in the National Biosolids Partnership (NBP) in 2011 and has 
maintained this level of certification to date. 

KUB appointed a Biosolids Program Coordinator to manage the environmental management system, 
ensure process improvement and program quality, and coordinate with the contractor and internal 

In 2006, KUB replaced its plate and frame biosolids dewatering system with a new centrifuge process, 
which reduces chemicals necessary for the process, lowers maintenance costs, and produces biosolids 
with lower pH levels and no lime. This allows for repeat land application to farms, lowering 
transportation costs and associated emissions. Without the lime, the product is also less odorous.  

KUB implemented a third party contract for operations and maintenance of equipment for the biosolids 
land application program to ensure quality and adequate resources and staffing. The contractor 
operates the centrifuge and transports and land applies the product to the fields. In addition, they 
manage the biosolids permitting process with the state and provide regulatory reporting 

KUB’s biosolids product was registered with the Tennessee Department of Agriculture as a fertilizer and 
is used as an alternative to commercial fertilizers by farmers. On an annual basis, approximately 
$900,000 a year of cost savings is realized among the farmers that receive the biosolids. 

In addition to application to regional farms, KUB is evaluating alternative solutions for application of the 
biosolids product. Discussions have been ongoing with the local landfill to determine if they may use the 
biosolids as a soil amendment to landfill cap material instead of using fertilizers.  

KUB completed a solids process control manual that  provided a State Point Analysis tool, which will aid 
in sludge inventory controls, as  well as final clarification monitoring. The initial study was completed to 
further optimize operational strategies for solids management. 

KUB developed a website and brochures for the biosolids program, to provide educational information 
to the public. KUB also established a public mailbox to receive program inquiries and feedback. 

KUB produces an annual performance report for the biosolids program, which is provided to the public. 
It includes results of the program goals and objectives, regulatory updates, any awards obtained by the 
plant, farmer interviews, and contractor performance results. 

KUB developed an internal dashboard that was identified by the NBP third party auditor as an industry 
best. The dashboard gives operations personnel a visual snapshot of data points coming from the 
various solids processes. The tool is beneficial for program analysis and decision-making, and operators 
use the data to monitor and assess plant performance. 

KUB participated in a Regional Unwanted Medication Collection event on April 23, 2016, and a KUB 
representative serves on the Medication Collection team, which normally organizes two to three events 
each year. A total of 596 pounds of over-the-counter and prescription medications (excluding paper and 
plastic) were collected and prevented from either going into the wastewater system and associated 
biosolids or a landfill. This brings the collection effort to over 18,000 pounds of medications since 2008.
