Climate change is causing an increase in flooding, rising sea levels, and new weather patterns. These changes have a massive negative impact on older urban cities. In an urban environment, flooding is particularly an issue, especially if the sewer system is a Combined Sewer Outfall. Combined Sewer Outfalls, or CSOs, are outdated sewer systems that easily become overwhelmed during rain events. During dry conditions, sewage and rainwater make their way to the water treatment plant normally. However, when the system reaches capacity, especially when it rains, the sewer can only carry so much runoff and waste to the water treatment plant. The sewer will then fill up with excess sewage and storm water. This waste is then dumped untreated into the closest water body. CSOs contribute to flooded basements, homes, and streets. Children are often seen playing in contaminated water. This is an environmental justice issue for residents and families living in Camden.
