Combined Sewer Systems
Many of New Jersey’s oldest cities still rely on combined sewer systems — systems in which stormwater runoff from city streets feeds into sewer lines and is treated, along with sewage, by treatment plants. Some of these systems are more than 100 years old.
During heavy rainfalls the volume of stormwater in the older, combined systems can overwhelm the capacity of the treatment plant. When that happens, combined sewage can overflow into area waterways, or back up into streets, public spaces such as parks, and sometimes even residential basements. This makes the sewage treatment plant operator vulnerable to lawsuits under the federal Clean Water Act.
Jersey Water Works’ initial efforts involve working with communities and utilities that have combined sewer systems, to help them identify and implement the appropriate combination of strategies to reduce sewer overflows.
