The Districts’ biosolids management strategy allots a small percentage of its biosolids capacity for the 
development of new and emerging technologies. The Districts currently have one contract for the 
development of a biosolids-to-fuel facility.  

The Districts continually evaluate dewatering equipment for operational efficiencies and to minimize the 
volume of biosolids hauled offsite. The Districts are pilot testing a biosolids dryer that can increase the 
biosolids total solids content to approximately 90%.    

The Districts have one hauling contract that utilizes natural gas-fueled vehicles for a portion of its 
contracted hauling. Hauling with natural-gas vehicles provides air quality benefits, such as reduced air 
and greenhouse gas emissions compared to hauling with diesel-fueled vehicles.  

 The Districts are dedicated to develop expertise in all aspects related to biosolids.  Districts staff 
responsibilities include; biosolids operations, biosolids contract management; facility planning and 
permitting (including air quality and water quality), regulatory reporting, monitoring regulatory issues, 
and new technology evaluation.  

Performance Measures & Results 



Beneficially used biosolids in 2015: 85% of the over 440,000 wet tons produced was beneficially 
reused (75% composted and 10% land applied) 



*Please note that the Districts are in the process of developing performance measures for its 
biosolids management program.

Innovation initiatives adopted that encourage risk-taking, and that are adequately funded and 

The Sanitation Districts invested $2.3 million to restore the Bixby Marshland, a 17-acre marsh, located to 
the northwest of our largest treatment facility, Joint Water Pollution Control Plant (JWPCP). The 
Sanitation Districts owned-and-operated marshland is open the first Saturday of the month with docents 
available onsite to provide tours. Tours are also scheduled by appointment for groups, including 
agencies, associations, and businesses.    

The JWPCP Citizens' Advisory Committee (CAC) was formed in 1978 to provide a forum for community 
input regarding the Sanitation Districts' operations and to help guide the Sanitation Districts in its efforts 
to be a better neighbor to the surrounding community. The CAC members also act as a conduit to
