4) Energy efficiency—The CCMUA has taken several steps to optimize energy efficiency, including:  
  

 

infiltration/inflow reduction programs to reduce pumping and treatment requirements 

 

addition of variable frequency drives in pump motors to reduce energy usage 

 

at the wastewater treatment plant, optimize primary treatment in order to reduce reliance of 
the more energy intensive secondary treatment facilities  

 

upgrade pure oxygen system with more energy efficient vapor pressure swing adsorber facility 

 

upgrade aerator blades with more energy efficient model 

 

installation of solar panels that provide 10% of the plant's electricity needs 

 

installation of sewage to heat facility to capture the latent heat of sewage and use it to heat 
boilers during colder weather 

 

in the process of constructing sludge digestion and combined heat and power facilities to 
convert digester biogas into electricity.   

 

This project should be completed by mid-2018 and should provide 50-60% of the plant's electricity 
needs  
  
5) Energy generation and recovery—  

 

Installation of solar panels that provide 10% of the plant's electricity needs 

 

installation of sewage to heat facility to capture the latent heat of sewage and use it to heat 
boilers during colder weather 

 

in the process of constructing sludge digestion and combined heat and power facilities to 
convert digester biogas into electricity.   

This project should be completed by mid-2018 and should provide 50-60% of the plant's electricity 
needs  
  
6) Watershed stewardship---The CCMUA's primary goal, and reason for being as a clean water utility, is 
to protect the water quality of Camden County's rivers and streams.  Its first project was to eliminate 
discharges of 52 wastewater treatment plants into the County's interior streams and convey those flows 
to the CCMUA's regional plant.  This resulted in 99% reductions in fecal coliform levels within the 
interior streams of Camden County within 3 years.    
  
At the regional wastewater treatment plant, permit compliance is the floor of the CCMUA's aspirations, 
not the ceiling.  The goal is to optimize water quality of the plant effluent to the maximal extent 
practicable.  During the past 5 years, the CCMUA's effluent quality has averaged less than 5 ppm of TSS, 
even though the permit limit is 30 ppm.  This has been accomplished through changing the 
organizational culture and concurrently upgrading each component of the wastewater treatment 
process.    
  
In addition, the CCMUA has also sought to protect Camden's clean water resources by: developing a 
water conservation ordinance, planting green infrastructure to reduce stormwater loading to the City's 
combined sewer system, thereby protecting that stormwater from being contaminated in the combined 
sewer system.  This also reduces the potential of combined sewage overflows to the Delaware River, 
cleanup of riverfront brownfields, thereby eliminating contaminated runoff into the Delaware River, 
elimination of eight combined sewer overflow outfalls and installation of netting systems on the 
remaining 30 combined sewer overflow outfalls to protect the Delaware River from solids during wet 
weather events
