The U.S. Environmental Protection Agency (EPA) has recently highlighted the critical need for substantial investments in wastewater and stormwater management systems across the country. According to the EPA's 2022 Clean Watersheds Needs Survey, an estimated $630 billion will be required over the next 20 years to maintain and modernize these essential infrastructures. This article discusses the specifics of the report, the significance of these investments, and the federal funding resources available to support this vital work.

The Scope of the Challenge

The EPA's survey underscores the vast scope of the challenge facing America's wastewater and stormwater management systems. The wastewater infrastructure in many communities is aging and requires significant water infrastructure improvements to meet current and future demands. This includes publicly owned treatment works, stormwater infrastructure, nonpoint source control, and decentralized wastewater treatment systems such as septic tanks​.

Wastewater Management

Wastewater Management involves the collection, treatment, and disposal of water that has been used in homes, businesses, industries, and agriculture. This water, known as wastewater, includes everything from sanitary sewer system to runoff from agricultural fields and industrial processes. The primary goals of wastewater management are to protect the nation's water quality and public health and prevent pollution of natural water bodies.

Stormwater Management

Stormwater Management refers to the control and use of rainwater runoff. When rain falls on impervious surfaces like roofs, streets, and sidewalks, it collects pollutants and flows into storm drains and local waterways. The main objectives of stormwater management are to reduce the speed and volume of stormwater runoff, improve the quality of water bodies, and prevent flooding and erosion.


Why Investment is Crucial

Investing in wastewater and stormwater management is critical for several reasons:

Protecting Public Health

    • Preventing Waterborne Diseases: Proper treatment prevents the spread of diseases caused by pathogens found in untreated sewage. Ensuring that water treatment facilities are up to date and functioning effectively is essential for maintaining public health​.
    • Ensuring Safe Drinking Water: Upgrades to wastewater and stormwater systems help prevent contaminants from entering drinking water supplies, ensuring that communities have access to safe and clean water.

Environmental Protection

    • Reducing Pollution: A modernized stormwater system can better handle stormwater runoff, preventing harmful pollutants from reaching rivers, lakes, and oceans. This helps protect aquatic ecosystems and biodiversity.
    • Supporting Aquatic Ecosystems: Effective wastewater treatment reduces nutrient loads that can cause algal blooms and dead zones in water bodies, thus supporting healthier aquatic ecosystems.

Compliance with Regulations

    • Meeting Clean Water Act Standards: Investments are necessary to ensure compliance with the Clean Water Act, which mandates that water bodies be fishable and swimmable. Upgrading facilities helps avoid legal penalties and ensures environmental standards are met.
    • Reducing Non-Compliance Costs: By investing in water infrastructure now, communities can avoid the higher costs associated with fines, emergency repairs, and health impacts from non-compliance with environmental regulations.


Federal Government Funding Initiatives

To address these wastewater infrastructure needs, significant federal funding has been allocated through various programs:

Bipartisan Infrastructure Law

Biden’s Bipartisan Infrastructure Law, passed in 2021, marks the largest federal investment in water infrastructure in U.S. history. This law allocates a total of $50 billion specifically for water infrastructure projects. Of the $50 billion, nearly $13 billion is dedicated to wastewater and stormwater management​. This funding aims to upgrade aging infrastructure, address emerging contaminants, and support resilience against climate change impacts.

Clean Water State Revolving Fund

Established in 1987, the Clean Water State Revolving Fund has been a cornerstone of federal support for water infrastructure projects. The fund provides low-interest loans to states, municipalities, and other local entities for water quality improvement projects. Since its inception, the CWSRF has supported over $160 billion in water infrastructure projects, financing efforts such as wastewater infrastructure upgrades, stormwater management systems, and nonpoint source pollution control.

Water Infrastructure Finance and Innovation Act (WIFIA) Program

The WIFIA program, created in 2014, offers long-term, low-cost supplemental loans for regionally and nationally significant water projects. This program helps to bridge funding gaps for large-scale and complex projects that might otherwise struggle to secure sufficient financing. Since 2018, the WIFIA program has issued over $43 billion in loans to support critical infrastructure projects. These funds have facilitated the construction and modernization of treatment facilities, stormwater systems, and other vital water infrastructure.


Regional Highlights

Of the $630 billion needed for clean water investments, $7.7 billion is allocated for water reuse, marking a 3% increase since 2012. This need was highlighted in 31 states, up from 25 states in 2012. California, Florida, Virginia, Texas, and New Mexico reported the highest increases in water reuse needs relative to 2012. The survey found that the most common uses for recycled water are groundwater recharge and irrigation, with expected increases in other non-potable and potable reuse applications in the future.

The recent survey by the United States Environmental Protection Agency or EPA highlights a pressing national need for substantial investments in wastewater and stormwater management. Ensuring the health of our communities and the environment requires modernizing and maintaining these critical infrastructures. With significant federal funding initiatives in place, there is a strong foundation to support these necessary upgrades. However, ongoing efforts and investments will be essential to meet the goals of the Water Act and protect the nation's waters for future generations.


Wastewater Treatment FAQs

What is the EPA definition of wastewater?

The Environmental Protection Agency (EPA) defines wastewater as water that has been used and contaminated by various activities, such as domestic, industrial, and agricultural processes. This includes water from sinks, showers, toilets, and industrial processes that contain waste products and pollutants needing treatment before it is safe to be released back into the environment.

What is the Clean Water Act Needs Survey?

The Clean Watersheds Needs Survey (CWNS) is a comprehensive assessment conducted by the EPA every four years to estimate the capital investment necessary to meet the water quality goals of the Clean Water Act. The survey collects data on the needs of publicly owned wastewater treatment facilities, stormwater management systems, and other related water infrastructure​.

What is the US water policy?

The US water policy encompasses a range of laws and regulations aimed at managing water resources, ensuring safe drinking water, protecting water quality, and addressing water scarcity. Key components include the Clean Water Act, the Safe Drinking Water Act, and various state and local regulations that govern water use, conservation, and pollution control​.

How has the United States acted to address water pollution?

The United States has addressed water pollution through several legislative and regulatory measures, most notably the Clean Water Act of 1972. This Act established the framework for regulating discharges of pollutants into waters and set water quality standards. The EPA enforces these regulations, monitors water quality, and provides funding for water treatment infrastructure. Other actions include the Safe Drinking Water Act and various state-level initiatives.

Where is most treated wastewater released?

Most treated wastewater in the United States is released into surface waters such as rivers, lakes, and oceans. After undergoing extensive treatment to remove contaminants, the treated effluent is discharged in compliance with environmental regulations to ensure it does not harm the receiving water bodies.
