EPA Allocates $80 Million to Upgrade Trenton’s Sewer System, Addressing Combined Sewer Overflow Issues
The U.S. Environmental Protection Agency (EPA) has announced approximately $80 million in funding to upgrade Trenton, New Jersey’s aging sewer system. This investment aims to address longstanding combined sewer overflow (CSO) issues that have plagued the city, impacting water quality and public health. The funding, made available through the Bipartisan Infrastructure Law, will support critical infrastructure improvements to reduce pollution and enhance the city’s wastewater management capabilities.
Understanding Combined Sewer Overflows
Combined sewer systems, common in older cities like Trenton, collect stormwater runoff and sewage in a single pipe system. During periods of heavy rainfall or snowmelt, the volume of wastewater can exceed the capacity of the treatment plant. This leads to CSOs, where untreated sewage and stormwater are discharged directly into nearby waterways, such as the Delaware River. These overflows can contaminate recreational waters, harm aquatic ecosystems and pose risks to public health.

The Trenton Project: Scope and Objectives
The $80 million allocated to Trenton will fund several key projects designed to mitigate CSO events. According to the EPA, the upgrades will focus on increasing the capacity of the city’s wastewater treatment plant and implementing green infrastructure solutions. EPA’s announcement details that these improvements will reduce the frequency and volume of CSOs, improving water quality in the Delaware River and its tributaries.
Bipartisan Infrastructure Law Funding
The funding for Trenton’s sewer system upgrades is part of a larger, nationwide investment in water infrastructure made possible by the Bipartisan Infrastructure Law, signed into law in November 2021. The law allocates billions of dollars to address critical water infrastructure needs across the country, including upgrading aging sewer systems, replacing lead service lines, and improving water treatment facilities. The EPA is administering these funds through various grant programs, prioritizing projects that address environmental justice concerns and benefit underserved communities.
Impact on the East Trenton Community
Even as the sewer system upgrades are city-wide, the improvements are expected to have a particularly positive impact on the East Trenton neighborhood. This area has been the focus of recent environmental remediation efforts due to historic lead contamination from former pottery factories. Reducing CSOs will further protect the health of residents and improve the overall environmental quality of the neighborhood.
Statements from Officials
EPA Regional Administrator Lisa Garcia stated, “This investment is a game-changer for Trenton, providing critical funding to address long-standing sewer issues and protect public health and the environment.” Trenton Mayor Reed Gusciora added, “We are incredibly grateful for the EPA’s support. These upgrades will not only improve our water quality but also create jobs and stimulate economic growth in our city.”
Looking Ahead
The EPA anticipates that the Trenton sewer system upgrades will be completed within the next several years. The agency will continue to work closely with the city and other stakeholders to ensure the project is implemented effectively and delivers lasting benefits to the community. This investment represents a significant step towards a more sustainable and resilient water infrastructure system for Trenton and the surrounding region.
