 A Critical Oversight: Inadequate Sewage Systems and Monitoring Worsen New Jersey's Flood Crisis

TRENTON, NJ - July 16, 2025 – Beyond the sheer volume of rainfall, the recent devastating floods in New Jersey have spotlighted a critical underlying issue: the state's aging and often inadequate sewage infrastructure, coupled with a perceived lack of comprehensive, real-time flood monitoring. Experts and residents alike are raising concerns that these systemic failures are exacerbating the impact of increasingly intense weather events.

The problem of insufficient sewage capacity is a long-standing one.¹ Many of New Jersey's urban and even suburban areas rely on drainage systems built decades ago, designed for a different climate and a smaller population. As development has expanded, replacing natural landscapes with impermeable surfaces like concrete and asphalt, the volume of stormwater runoff has dramatically increased. These existing sewer systems, often combining wastewater and stormwater in the same pipes, quickly become overwhelmed during heavy downpours.²

"When you have six inches of rain in a few hours, the pipes simply can't handle it," explained Dr. Evelyn Reed, an environmental engineer specializing in urban hydrology. "The consequence isn't just surface water pooling; it's often raw or partially treated sewage backing up into streets, basements, and even natural waterways. This poses significant public health risks and environmental damage, contaminating drinking water sources and harming ecosystems."³

Reports from affected areas after the recent floods have included accounts of foul-smelling water in residential areas and debris indicating sewage overflow. This isn't merely an inconvenience; it can spread waterborne diseases, impact aquatic life, and necessitate costly and hazardous clean-up operations.⁴

Compounding this infrastructure deficit is the perceived gap in real-time flood monitoring. While some systems exist, residents and emergency responders often rely on anecdotal reports and visual assessments until water levels reach critical stages.

"We need a more proactive approach," stated a local firefighter, who wished to remain anonymous. "By the time we're getting calls about cars submerged, the damage is already done. If we had more granular, real-time data on water levels in key flood zones and an automated alert system, we could close roads earlier, divert traffic, and perhaps even evacuate vulnerable areas with more lead time."

Effective flood monitoring systems involve a network of sensors measuring water levels, rainfall intensity, and even soil moisture.⁵ This data, when analyzed using predictive analytics, can provide early warnings, allowing authorities to make informed decisions regarding evacuations, resource allocation, and infrastructure protection. Without this, response is often reactive, scrambling to mitigate damage rather than prevent it.

The economic consequences of these shortcomings are substantial, extending beyond immediate property damage to include business disruptions, increased healthcare costs due to contamination, and long-term environmental remediation expenses. As climate change continues to bring more frequent and intense rainfall, the urgency to address New Jersey's sewage and monitoring vulnerabilities has never been greater. Calls are mounting for significant investment in infrastructure upgrades and the implementation of advanced, integrated flood monitoring systems to protect lives, property, and the environment.
