As cities across the United States grapple with crumbling sewage systems, a recent report highlights the staggering cost needed to repair this aging infrastructure.
The Tennessee Advisory Commission’s first-of-its-kind Report of the Tennessee Advisory Commission on Intergovernmental Relations found that the Volunteer State needs more than $3 billion by 2027 to repair, replace and expand its wastewater treatment systems.
The report says that while the state has already invested heavily in upgrading wastewater infrastructure in recent years by distributing more than $500 million in federal American Rescue Plan funding, “it is likely that Tennessee’s wastewater systems will need to spend billions to pay for the repair, replacement and expansion of their infrastructure.”
According to a Tennessee Lookout article, many of the state’s systems are already under scrutiny by state and federal environmental regulators.
“Scores of local government-operated waste systems are under moratoriums issued by the Tennessee Department of Environment Conservation because of sewage overflow problems,” the article reads. “The moratoriums bar the facilities from any future expansions until the often-costly overflow problems are fixed... The U.S. Environmental Protection Agency has also found Clean Water Act violations in three Tennessee municipal systems: Springfield, Knoxville and Nashville. Nashville is now under a court-ordered agreement with the federal agency to make nearly half a million dollars in repairs to continue to serve its existing customer base.”
The urgent need for investment in wastewater infrastructure is not isolated to Tennessee; it reflects a nationwide crisis of aging wastewater systems that are underfunded and increasingly susceptible to failures. As this infrastructure continues to age and degrade, cities are faced with significant financial challenges to maintain and upgrade these essential systems.
The Scope of the Problem
The situation in Tennessee is symptomatic of a broader trend affecting municipalities throughout the country. According to the American Society of Civil Engineers (ASCE), the U.S. faces a water infrastructure funding gap that could exceed $1 trillion over the next two decades. More than 240,000 water main breaks occur each year, and aging sewage systems contribute to a variety of public health and environmental issues, including water contamination and untreated sewage spills.
Local governments are particularly vulnerable, with many struggling to meet both operational costs and necessary upgrades. The situation is exacerbated by a lack of federal funding, leading to a reliance on state and local budgets, which are often stretched thin.
Financial Challenges
Maintaining and upgrading wastewater infrastructure requires substantial investment, and the financial burden falls disproportionately on local governments. The costs can be daunting: studies indicate that for many municipalities, maintaining current systems could consume 30-50% of their annual budget.
The Tennessee report outlines a range of critical needs, from repairing old pipes to upgrading treatment plants to meet modern standards. While some municipalities have implemented user fees to cover costs, these fees can be unpopular and politically challenging. Additionally, the reliance on state and federal grants can be inconsistent, leaving many cities without the funding they need to address immediate issues.
Environmental and Public Health Concerns
Failing wastewater infrastructure poses significant risks to public health and the environment. Inadequately treated sewage can contaminate bodies of water, leading to health risks for communities that rely on those water sources for recreation and drinking water. The impact is particularly severe in low-income neighborhoods, which may lack the resources to respond effectively to sewage overflows or contamination incidents.
Cities in Crisis
Cities across the U.S. illustrate the challenges of aging wastewater systems.
These cities have turned to various strategies to address their infrastructure needs. Some have pursued public-private partnerships to leverage additional resources, while others have sought innovative financing mechanisms to fund their projects. However, the scale of investment needed often requires difficult trade-offs with other critical services, such as education and public safety.
The federal government has recognized the urgent need to address wastewater infrastructure issues, with initiatives like the Water Infrastructure Finance and Innovation Act (WIFIA) providing low-interest loans for water and wastewater projects. The Bipartisan Infrastructure Law also allocates significant funding to help local governments improve their systems. However, critics argue that these measures are insufficient to meet the scale of the crisis.
Local governments often seek creative financing solutions to bridge funding gaps. Some have explored green infrastructure projects that utilize natural systems to manage stormwater, thereby reducing the burden on traditional sewage systems. Others have considered implementing tiered pricing structures for water usage, where higher usage results in higher fees, to incentivize conservation and generate revenue for infrastructure investments.
Community Engagement and Education
Public engagement plays a critical role in addressing the challenges of aging wastewater infrastructure. Community education about the importance of maintaining and investing in these systems can foster public support for necessary funding measures. Municipalities that involve residents in decision-making processes often find it easier to garner support for rate increases or new funding initiatives.
Transparency about the current state of infrastructure and the potential risks of inaction can also mobilize community advocacy. As cities work to modernize their systems, they must also prioritize communication with their constituents, making the case for why investments in wastewater infrastructure are essential for public health and environmental sustainability.
The Path Forward
Addressing the challenges of aging wastewater infrastructure requires a comprehensive approach that includes increased funding, innovative financing solutions, community engagement, and strategic planning. As seen in Tennessee, the need for immediate action is critical, but the solutions must be sustainable and equitable.
Long-term planning is essential for ensuring that infrastructure can meet future demands, particularly as climate change continues to intensify. Many cities are beginning to integrate climate resilience into their infrastructure planning, recognizing that a proactive approach is necessary to safeguard public health and environmental quality.
As municipalities look to improve their water and wastewater systems, GPRS will be here to help ensure these projects stay on time, on budget, and safe. Through our subsurface damage prevention, existing conditions documentation, and project and facility management services, we help safeguard water and wastewater infrastructure.

GPRS Hosts Water & Sewer Damage Awareness Week
The cost to maintain the United States' aging wastewater infrastructure is not just a financial issue; it is a public health, environmental, and social justice concern.
This is why GPRS sponsors Water & Sewer Damage Awareness Week (WSDAW), an education and safety initiative for water and wastewater professionals in municipalities, organizations, and large facilities. Through these free safety presentations, we hope to help these individuals and entities regain control of their critical water and wastewater infrastructure.
