Water infrastructure investment in the United States spans treatment plants, conveyance systems, stormwater controls, decentralized wastewater, drinking-water projects, and federal financing. The figures below distinguish reported capital needs, scheduled allocations, program financing, observed capacity, estimates, and forecasts across explicit periods.

National Water Infrastructure Investment Needs and Funding Gaps
EPA’s 2022 Clean Watersheds Needs Survey Report to Congress reported $630.1 billion in U.S. clean-water infrastructure needs for the 20-year period from January 1, 2022 through December 31, 2041. These are reported capital needs, not measured spending, and EPA cautions that a listed need does not necessarily mean that no funding exists; the survey may also understate true nationwide need.
About 55% of the 2022 CWNS total was wastewater infrastructure. Six states—New York, California, Florida, Virginia, Louisiana, and Georgia—accounted for 42% of reported clean-water needs, with New York and California each reporting more than $50 billion and the other four each reporting more than $25 billion.
| Geography or benchmark | Reported need | Period and definition |
|---|---|---|
| United States | $630.1 billion | 2022–2041 clean-water capital needs |
| Six named states | 42% of national reported needs | 2022 CWNS |
| New York and California | More than $50 billion each | 2022 reported clean-water needs |
| Florida, Virginia, Louisiana, and Georgia | More than $25 billion each | 2022 reported clean-water needs |
Per-capita figures show why national totals do not describe local investment pressure uniformly. The Northern Mariana Islands reported the highest clean-water need per capita at $7,203, followed by West Virginia at $6,182 and New Mexico at $5,799 in 2022.
EPA’s earlier 2017 report estimated about $655 billion in drinking-water and wastewater needs over 20 years, but that estimate is not directly comparable with the later CWNS scope. EPA’s Water Finance Center gives a broader estimate of more than $1 trillion needed for water infrastructure improvements over 20 years.
Clean-Water Infrastructure Investment Data by Treatment and Conveyance
The CWNS population included 17,544 publicly owned treatment works serving 270.4 million people in 2022. The category figures below are estimated capital needs for the 2022–2041 horizon, not completed projects or annual expenditure.
| Clean-water category | Reported need, 2022–2041 |
|---|---|
| Secondary wastewater treatment | $66.6 billion |
| Advanced wastewater treatment | $83.6 billion |
| Conveyance-system repair | $110.1 billion |
| New conveyance systems | $41.0 billion |
| Combined-sewer-overflow correction | $36.5 billion |
The five EPA-reported wastewater treatment and conveyance categories above total $337.8 billion when added, a derived sum rather than a separately published headline total. Conveyance repair is the largest listed category, and its definition excludes new conveyance systems.
Urban areas accounted for $404.0 billion in wastewater and stormwater needs for 2022–2041, compared with $57.0 billion for rural areas. EPA’s urban/rural analysis excludes nonpoint-source and decentralized categories, so those amounts should not be treated as a complete urban-versus-rural total for every clean-water investment type.
Stormwater, Nonpoint-Source, Decentralized, and Reuse Investment Trends
Stormwater-management needs reached $115.3 billion, or 18.3% of total CWNS needs, for 2022–2041. EPA reported stormwater needs from 51 states and territories in 2022, with Virginia at $30.2 billion and California at $16.2 billion.
The 2022 CWNS report says stormwater needs increased 385% from 2012, an increase of $91.5 billion. EPA notes that category definitions and reporting changed between survey rounds, so this comparison is not a pure like-for-like spending trend.
Nonpoint-source-control needs were $94.4 billion, or 15.0% of total needs. Within that category, agricultural cropland needs were $27.6 billion across 43 states, while hydromodification needs were $33.5 billion across 35 states.
| Category | Reported need | Coverage or comparison |
|---|---|---|
| Stormwater management | $115.3 billion | 18.3% of total; 2022–2041 |
| Nonpoint-source control | $94.4 billion | 15.0% of total; 2022–2041 |
| Agricultural cropland | $27.6 billion | 43 states; 2022–2041 |
| Hydromodification | $33.5 billion | 35 states; 2022–2041 |
| Decentralized wastewater | $74.7 billion | 11.9% of total; 2022–2041 |
| Water reuse | $7.7 billion | 2022–2041 |
Decentralized wastewater-treatment needs were $74.7 billion, or 11.9% of total needs, and increased 172% from 2012, a reported increase of $47.3 billion. Water-reuse needs were $7.7 billion, up 3%, or $0.2 billion, from 2012; reporting coverage rose from 25 states in 2012 to 31 states in 2022.
Drinking-Water and Lead-Service-Line Infrastructure Investment Statistics
The EPA’s Water Infrastructure Investments overview says the Infrastructure Investment and Jobs Act, enacted in 2021, delivered more than $50 billion to EPA for drinking-water, wastewater, and stormwater infrastructure. The headline is a federal authorization or investment amount, not the same measure as disbursed project spending.
IIJA funding specifically included $4 billion for emerging contaminants through the Drinking Water State Revolving Fund. A separate five-year schedule provided $15 billion for lead-service-line replacement through the Drinking Water SRF from FY2022 through FY2026, or $3.0 billion per fiscal year.
The congressional IIJA funding table lists $1.0 billion for emerging-contaminant Clean Water SRF funding over FY2022–FY2026. These are scheduled federal allocations and should not be conflated with total project investment.
ASCE reported that federal capital spending’s share of total U.S. water capital spending fell from 63% in 1977 to 9% in 2017. Its policy statement also cited an $81 billion drinking-water and wastewater funding disparity by 2039; that figure is a forecast based on ASCE trend assumptions.
Federal Water Infrastructure Funding and Revolving-Fund Allocations
The IIJA schedule provides a useful view of planned federal support by program and fiscal period. The figures below are scheduled allocations from FY2022 through FY2026 unless a single fiscal year is shown.
| Program or line | Scheduled amount | Period |
|---|---|---|
| Clean Water SRF | $11.713 billion | FY2022–FY2026 |
| Drinking Water SRF, excluding separately listed lead funding | $11.713 billion | FY2022–FY2026 |
| EPA State and Tribal Assistance Grants | $55.426 billion | FY2022–FY2026 |
| Groundwater Clean Water SRF | $1.0 billion | FY2022–FY2026 |
| Lead-service-line Drinking Water SRF | $15 billion | FY2022–FY2026 |
For the Clean Water SRF, the table lists $1.902 billion in FY2022, $2.403 billion in FY2024, and $2.603 billion in FY2026. The Drinking Water SRF table lists $1.902 billion in FY2022 and $2.403 billion in FY2024.
The program totals describe federal schedules, not the entire financing stack for water infrastructure. Revolving-fund allocations can support projects through loan and grant mechanisms, while project-level investment may include other sources.
Water Infrastructure Investment Outcomes: Financing, Capacity, and Benefits
EPA’s WIFIA 2024 Annual Report reported 138 closed loans and $21 billion in WIFIA financing through December 2024. Those projects represented $47 billion in total water infrastructure investment, a broader project-investment measure than WIFIA financing alone.
| WIFIA outcome | Program-reported result | Period |
|---|---|---|
| Closed loans | 138 | Through December 2024 |
| WIFIA financing | $21 billion | Through December 2024 |
| Total project investment | $47 billion | Through December 2024 |
| Treatment capacity improved | 5,000 MGD | Through December 2024 |
| Beneficial-use water recycled, recharged, or redirected | 500 MGD | Through December 2024 |
| Wastewater treatment improved before discharge | 1,110 MGD | Through December 2024 |
WIFIA projects addressed more than $1 billion in lead-related drinking-water investment and eliminated an estimated 350 water-main breaks per year. The program also reported 155,000 jobs created, $7 billion in total savings for borrowers and ratepayers, and a 100% repayment success rate; the last figure is a program repayment record, not a return-on-investment rate.
EPA’s Water Finance Center estimates approximately 240,000 water-main breaks per year in the United States and approximately $2.6 billion per year lost as water mains leak treated drinking water. These are EPA estimates rather than a directly observed national census or an audited national loss account, and WIFIA accomplishments are program-reported rather than a census of all U.S. water infrastructure investment.
