Federal data and industry experts point to increasing overflows, rising utility bills, and mounting public health risks tied to deteriorating wastewater infrastructure.

A nationwide network of aging wastewater systems is placing growing strain on public health and local budgets, with federal estimates indicating that hundreds of billions of dollars will be required to repair and modernize critical infrastructure, according to a report by The Epoch Times.
The Environmental Protection Agency has projected that approximately $630 billion in investment will be needed to address deteriorating wastewater systems, as utilities report tens of thousands of failures annually and increased pressure from population growth and extreme weather conditions.
The American Society of Civil Engineers gave U.S. wastewater infrastructure a D-plus rating in its 2025 report card, citing long-term underfunding and declining replacement rates. While consumer costs have risen, infrastructure renewal has slowed, with replacement rates dropping from 3 percent to 2 percent over the past decade.
Monthly wastewater bills increased from roughly $35 to nearly $65 between 2010 and 2020, according to ASCE data, and continued rising in subsequent years. Despite these increases, analysts said revenue has not kept pace with the cost of maintaining and upgrading systems.
The scale of the issue is reflected in overflow incidents. As of 2025, the EPA estimated between 23,000 and 75,000 sanitary sewer overflows annually, excluding additional cases involving backups into homes and buildings. Causes include blockages, pipe failures, design limitations, and system overload.
An EPA spokesperson said the agency is working to accelerate infrastructure investment through federal programs, including funding initiatives that allocated $13 billion in 2025 through mechanisms such as the Clean Water State Revolving Fund and the Water Infrastructure Finance and Innovation Act. The agency also noted that the nation’s sewer systems represent infrastructure assets valued at more than $1 trillion.
Despite these efforts, infrastructure groups warn that the system has experienced prolonged neglect. The Association of State Floodplain Managers described wastewater networks as suffering from “chronic underinvestment,” according to its analysis.
The United States maintains an estimated 800,000 miles of sewer pipes, far exceeding the length of the National Highway System. Many of these pipes are decades old, with an average age of about 45 years, and some systems in the eastern United States dating back more than a century.
Failures in these systems can pose direct health risks. Laura Underwood, director of digital water solutions at Locus Technologies, said overflows and system breakdowns can release pathogens into waterways, increasing the likelihood of gastrointestinal illness, skin infections, and contamination of drinking water supplies.
She said delays in infrastructure upgrades are likely to result in more frequent overflows and untreated discharges, contributing to degraded waterways and broader environmental impacts.
The risks were highlighted by a major incident earlier this year, when more than 250 million gallons of sewage entered the Potomac River near Washington, D.C., following a pipe failure. The event required months of repair work and disrupted nearby communities.
Industry professionals say problems are not limited to large municipal systems. Steven Morgan, a plumbing expert, said aging sewer lines connecting homes to main systems are increasingly failing due to corrosion, cracks, and root intrusion. He said homeowners may face repair costs ranging from $8,000 to $25,000 when these lines collapse.
Such failures can lead to sewage backing up into homes during heavy rainfall, raising the risk of contamination. Experts warn that exposure to untreated wastewater may involve bacteria, viruses, parasites, and chemical pollutants, including PFAS compounds.
According to federal data, approximately 7.15 million Americans are affected annually by waterborne illnesses, with more than 100,000 hospitalizations and thousands of deaths linked to these conditions.
Beyond surface-level contamination, deteriorating infrastructure also affects groundwater systems. Studies have found that leaking sewer lines can introduce contaminants into aquifers, while treatment plant bypasses can release untreated wastewater into rivers and other surface waters.
Industry leaders say many municipalities are beginning to invest in more durable materials and system upgrades, particularly in areas experiencing population growth or increased flooding. However, a 2025 congressional report identified incomplete data as a barrier to fully assessing the scope of the problem and estimating the total cost of repairs.
Recent federal and state-level funding efforts have targeted infrastructure improvements, including projects in North Carolina and Maine, but experts say these measures represent only a portion of the resources required.
Officials and industry specialists say the combination of aging systems, rising costs, and environmental pressures underscores the need for long-term planning and sustained investment to prevent further failures and protect public health.
