Outdated sewage systems send raw sewage and stormwater through the same pipes, leading to flooding issues during heavy rainfall.
Zoë Read with WHYY reports – Camden County is investing $400 million dollars in infrastructure projects to reduce the amount of sewage and stormwater that overflows into local waterways.
The county is calling the project, which aims to improve water quality and mitigate flooding, “the most ambitious water quality initiative” in its history.
“It’s a comprehensive strategy that addresses every major factor affecting the health of our rivers, lakes and streams. Perhaps most importantly, this represents a new way of thinking about water quality,” said Scott Schreiber, executive director of the Camden County Municipal Utilities Authority, or CCMUA.
Unlike modern infrastructure, which utilizes separate piping systems, older sewer systems send stormwater and sewage through the same underground pipes.
During heavy rain, this combined sewer and stormwater system can overflow, spilling raw sewage into the region’s rivers and streams.
Camden’s main waterways, the Cooper and the Delaware rivers, often contain fecal bacteria levels that make it unsafe for humans to swim, fish or even kayak.
The overflow can also mean flooding in nearby communities. Flooding has caused basements and streets to flood in neighborhoods near the Cooper River and Newton Creek, including in Camden and Collingswood.
“The flooding impacts every business, every homeowner, everyone who’s trying to get to work,” Camden County Commissioner Jeffrey Nash said. “It is an economic problem, and it’s a human condition problem, because it harms everyone. People should not have to experience backup of sewer water in their homes, period.”
Pennsauken currently sends its combined sewer flow through the city of Camden, which makes its way to CCMUA’s treatment facility.
In the future, stormwater from Pennsauken and Camden will discharge into the Delaware River, while a separate sewage flow will be directed to the treatment plant.
The county is also investing millions more for green stormwater infrastructure such as rain gardens that capture water and reduce runoff, rehabilitating aging sewers, remediating sediment and restoring recreational lakes.
Officials say the countywide project will not only help the city of Camden, but also reduce flooding in neighboring communities like Collingswood.
“We can do very little to alter our geographic reality. We are bordered by the Cooper River to the north and Newton Lake to the south,” said Collingswood Mayor Daniela Solano-Ward. “Ultimately, protecting urban watersheds has fallen to local governments. But with 35 municipalities in Camden County, the weight of this lift is too heavy for any one of us to shoulder alone.”
