facility with a combined heat and power system, which will not only further reduce the tonnage 
generated from the current 40 tons per day down to 20 tons per day but also generate electricity to 
operate the wastewater treatment plant.  
  
3) Community Service—Because of the very close proximity (100 yards or so) of the CCMUA's 
wastewater treatment plant to a residential community, odor minimization is a very important, core, 
priority for our agency.   We have added $50 million in odor control facilities and implemented a zero 
tolerance policy with respect to leaving doors open, trucks untarped, chemical pumps running, etc.  In 
addition, we have taken several steps to reduce the odor potential from our biosolids. The first step we 
took was to replace our secondary thickening centrifuges with gravity belt thickeners.  We also 
significantly upgraded our belt filter presses.  This reduced the amount of sludge cake that we generated 
from 220 tons per day at 18% to about 160 tons per day at 25%.  As a result, we were capturing the 
same amount of solids but reducing the number of sludge hauling events by about 30%.   Then, we 
added a sludge drying facility which further reduced the 160 tons per day of sludge cake to 40 tons of 
dried biosolids.   This significantly reduced the odor potential of the plant.  Moreover, the dried biosolids 
are now a Class A byproduct.  We send this byproduct to a cement kiln in Maryland which uses the 
biosolids in lieu of coal, thereby reducing carbon footprint.   Finally, we are in the process of 
constructing a sludge digestion facility with a combined heat and power system, which will not only 
further reduce the tonnage generated from the current 40 tons per day down to 20 tons per day but 
also generate electricity to operate the wastewater treatment plant  
  
A measure of the importance of odor minimization to the CCMUA is that the neighborhood leaders have 
the personal cell phone of the Executive Director so that they can call at any time, 24/7, in the event of 
odor issues.  
  
Odor minimization is the floor of the CCMUA's community service aspirations, not the ceiling.  It 
represents a core goal to not interfere with the quality of life of our neighbors.  However, our main goal 
is to not only do no harm, but also to make a positive difference for our communities.  To that end, we 
have helped to found the Camden Collaborative Initiative (CCI), a collaboration among the USEPA, 
NJDEP, CCMUA, Camden City and over 40 environmental and community non-profits, such as the 
National Park Service, Nature Conservancy and the Trust for Public Land.   The CCI has formed six 
working groups each working on a different environmental challenge faced by Camden City:  

1.

 

combined sewage flooding 

2.

 

brownfields contamination 

3.

 

air emission impact 

4.

 

environmental education 

5.

 

sustainability and environmental justice 

6.

 

recycling and illegal dumping  

  
Thus far, the CCMUA and its partners have constructed over 50 rain gardens and five riverfront parks 
throughout Camden City, remediated several contaminated sites, worked on reducing air emissions 
from industries in the proximity of residential communities, developed a sustainability ordinance and a 
water conservation ordinance, developed an environmental education manual for Camden City schools, 
implemented a program for green infrastructure maintenance for at-risk youth and developed a robust 
recycling and illegal dumping prevention program.  The goal of the CCMUA is to become an anchor 
institution in Camden City, using its resources, and its partnerships, to improve the quality of life for 
Camden's residents.
