ENERGY GENERATION & RECOVERY  

 

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 
process  

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  

o

 

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

o

 

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
