Statewide training conference attendance Plant maintenance and operations staff attend CWEA 
and Tri-State annual conferences.  



Specialized training conference attendance (Maximo, asset management) Staff working directly 
with Maximo and asset management attend specialized conferences such as the Maximo Utility 
Working Group and WEF Utility Management Conference  



Involvement with WEF or CWEA committees Engineers and management participate in 
WEF/CWEA committees, including Collection Systems, Laboratory Practices, Plant Operations 
and Maintenance, Residuals and Biosolids, Utility Management,  



Water Reuse WateReuse Participation Attend training conferences. 




Indication of management commitment (e.g., standard operating procedures; board/executive 
management renewable energy conversion policy, including quantitative goals developed and 
shared with stakeholders)   


Internal energy sources evaluated (e.g., biogas, hydropower, heat in wastewater), and/or 
renewable energy sources evaluated on an ongoing basis (e.g., solar, wind, co-digestion)  


Recovery of digester gas in a combined heat and power (CHP) system, and boilers in place (for 
process and building heating)   


Conversion of digester biogas to electricity and heat, and/or transportation fuel Yes   

Cogeneration systems  

• Digester gas at the Dry Creek WWTP will be used to generate electricity  
• Digester gas at the Pleasant Grove WWTP, enhance by FOG and food waste co-digestion, 
will be used to generate CNG and electricity with a microturbine  

FOG receiving stations  


FOG receiving stations will be built to support the co-digestion systems  

Heat recovery systems  


Heat will be recovered from the cogeneration systems at each plant to heat the digestion 

Co-digestion systems  

• The City conducted a laboratory food waste co-digestion study with food waste collected 
from local restaurants and food companies  
• Food waste and FOG co-digestion was implemented into the Pleasant Grove WWTP 
expansion project  
• Co-digestion facilities are being added to both treatment plants  

Performance Measures & Results 


Reduce non-renewable energy use and carbon footprint  



Fuel half of the city’s refuse truck fleet with CNG  



Offset up to 50% of the plant’s power consumption with a digester gas fueled 
cogeneration system  


Renewable energy credit generation Both the Dry Creek and Pleasant Grove WWTPs are 
developing projects that will produce renewable energy credits
