A new bipartisan proposal in Congress aims to address mounting challenges in wastewater treatment in the United States, focusing on new contaminants such as PFAS and rising costs of infrastructure replacement.
Lawmakers introduced the Advanced Wastewater Treatment Assistance Act, which aims to help electric utilities implement next-generation treatment technologies.
The law comes as communities across the country face aging systems and stricter water quality regulations.
Increased pressure in wastewater systems
Wastewater treatment facilities across the United States collectively treat tens of billions of gallons of water each day.
However, many of these systems are not designed to remove new classes of pollutants, such as per- and polyfluoroalkyl substances (PFAS), that persist in the environment and pose health risks.
The growing need to address PFAS contamination is placing a significant financial burden on electric utilities. Advanced treatment methods that can remove these compounds, such as granular activated carbon and reverse osmosis, require significant capital and operating costs.
In states like Michigan, the fiscal burden is already apparent. The federal government estimates that needed wastewater infrastructure improvements will cost about $181 million in 2022, underscoring the scale of the challenge.
federal funding mechanism
The proposed bill outlines a five-year federal grant program designed to accelerate the adoption of advanced wastewater treatment technologies. The program allows up to $1 billion in funding to cover up to 50% of eligible project costs.
A key feature of this bill is its emphasis on equity in infrastructure investment. Nearly half of the funds would be set aside for communities with limited financial capacity, with provisions waiving cost-sharing requirements for these recipients.
This approach aims to ensure that smaller and economically constrained municipalities are not excluded from technological upgrades.
Administrative overhead is tightly controlled and capped at 1% for program management at the federal and state levels.
Technology and environmental impact
Beyond addressing PFAS, this bill highlights the broader environmental benefits associated with advanced wastewater treatment.
Technologies supported under this initiative can also reduce nutrient loads that contribute to harmful algal blooms, a persistent problem affecting major freshwater systems such as the Great Lakes.
The law also calls for national studies to evaluate the effectiveness of various treatment technologies in removing pollutants.
This research element is expected to inform future regulatory and investment decisions, especially as the scientific understanding of PFAS and similar compounds continues to evolve.
Policy background and industry response
This proposal reflects the federal government’s growing focus on water quality and infrastructure resiliency. PFAS contamination, in particular, has emerged as a priority for regulators and policy makers due to its widespread presence and resistance to traditional treatment processes.
Industry groups representing water utilities have expressed support for increased federal involvement, citing the need for coordinated investment and technical guidance.
“Water treatment companies are on the front lines of protecting public health and the environment, but the rising costs of advanced wastewater treatment technologies, especially to address emerging contaminants like PFAS, are placing a significant burden on communities and ratepayers,” said Adam Krantz, CEO of the National Association of Clean Water Agencies (NACWA).
“The bipartisan Advanced Wastewater Treatment Assistance Act would provide targeted federal assistance to utilities to deploy proven advanced treatment solutions, prioritize disadvantaged communities, and ensure Americans continue to have access to affordable, reliable, clean water.”
If enacted, this legislation would represent a significant federal intervention in the modernization of wastewater treatment systems. Its success will likely depend on how effectively funding is distributed and whether the supported technologies result in measurable improvements in pollutant removal.
