The Funding Landscape for Water in 2026
Water infrastructure is one of the most reliably funded categories in federal grants. Unlike discretionary programs that disappear with changing administrations, water funding flows through statutory programs that Congress reauthorized and expanded in the 2021 Infrastructure Investment and Jobs Act (IIJA). The EPA estimates the national water infrastructure funding gap at over $625 billion over 20 years. Federal and state programs together cover a fraction of that, but the available capital is substantial. The three main federal channels are: 1. EPA's Clean Water State Revolving Fund (CWSRF) and Drinking Water State Revolving Fund (DWSRF) — low-interest loans and some grants through state agencies 2. USDA Rural Development Water and Waste Disposal programs — grants and loans specifically for communities under 10,000 population 3. IIJA direct grant programs — Emerging Contaminants, lead service line replacement, and water sector cybersecurity State programs layer on top of these. California's Department of Water Resources alone administers programs totaling hundreds of millions annually. Florida's CWSRF is the state's largest infrastructure finance program. Texas has multiple targeted water grant programs through the Texas Water Development Board. Eligibility rules differ significantly across programs. Federal SRFs primarily fund public entities. USDA RD serves rural communities. Some IIJA supplemental programs extend eligibility to certain nonprofits and tribal entities. Know which channel fits your organization before applying.
EPA Clean Water State Revolving Fund (CWSRF)
The CWSRF is the backbone of municipal wastewater and stormwater financing in the United States. Congress capitalized the program starting in 1987, and states have revolving the fund ever since — meaning each loan repayment generates new lending capacity. The IIJA added $11.7 billion to the CWSRF over five years (FY2022-2026), roughly tripling annual federal capitalization. States match federal contributions at 20%. As of 2025, cumulative CWSRF lending nationally has exceeded $175 billion. What it funds: - Wastewater treatment plant construction, upgrades, and expansions - Sewer system rehabilitation and combined sewer overflow (CSO) projects - Stormwater management systems - Water quality restoration for lakes, estuaries, and nonpoint source programs - Green infrastructure projects (wetlands, bioswales, permeable pavement) Key terms: Loans are typically below-market rate (often 50-75% of market rate). Some states offer principal forgiveness — effectively grant funding — for affordability-impaired communities, small systems, and projects addressing lead service lines or emerging contaminants. Loan terms run up to 30 years. Who applies: Local governments, municipalities, counties, special districts, and state agencies. Private utilities are eligible in some states. Tribal governments qualify under separate provisions. How to access it: Applications go through your state environmental agency, not directly to EPA. Search '[state name] CWSRF application' for your state program. Most states have annual application windows with rolling applications for smaller projects. Florida's CWSRF, for example, provides low-interest loans with a priority list based on water quality impact and public health need. The fund prioritizes nutrient reduction, wastewater treatment, and stormwater projects. Projects serving disadvantaged communities may receive extended loan terms or principal forgiveness.

EPA Drinking Water State Revolving Fund (DWSRF)
The DWSRF parallels the CWSRF but focuses on public water system infrastructure — treatment plants, distribution pipes, storage tanks, and source water protection. The IIJA added $11.7 billion to the DWSRF over five years, with two major supplemental programs layered on top. Lead Service Line Replacement: The IIJA allocated $15 billion specifically for lead service line (LSL) replacement over five years. EPA allocated this to states as grants that flow through DWSRF programs. Most states require systems to inventory their LSLs before applying. Priority typically goes to systems serving low-income communities. Some states offer 100% principal forgiveness for qualifying small and disadvantaged systems. Emerging Contaminants (PFAS): The IIJA added $4 billion specifically for emerging contaminants, primarily PFAS compounds. In 2023, EPA issued the first enforceable drinking water standard for PFAS. Systems that must now comply with PFAS limits can access DWSRF funding for treatment upgrades. This is new, substantial funding — and demand is high. Who qualifies: Community water systems and non-profit non-community water systems. Systems serving fewer than 10,000 people receive priority in most states under the affordability provisions. Water sector cybersecurity: Under Section 1551 of the IIJA, EPA can provide technical assistance to water utilities on cybersecurity. This is not grant funding per se, but it connects small and medium utilities to resources they cannot otherwise afford. Application path: Through your state drinking water program. Most state programs post annual priority lists and application schedules on their websites.
USDA Rural Development Water and Waste Disposal
USDA Rural Development's Water and Waste Disposal (WWD) programs are the primary federal grant source for rural communities, and they fund a wide range of projects that SRFs often will not: small systems that cannot service traditional loans, communities in extreme poverty, and emergency replacement of failing infrastructure. The core programs: Water and Waste Disposal Loans and Grants (Section 306): The flagship program. Provides both low-interest loans (typically 1.375-3.25% depending on median household income) and grants for communities that cannot repay full loan costs. Grant percentages can reach 75% of project cost for the poorest communities. Typical project range: $100,000 to $25 million. No published ceiling per project, but very large projects are unusual. Eligibility: Municipalities, counties, special-purpose districts, associations, and nonprofit corporations in rural areas with populations up to 10,000. Tribal governments qualify. Cities under 50,000 may qualify in certain circumstances. What it funds: Construction, expansion, or repair of water and wastewater systems. Planning and design costs. Purchase of existing systems. Well drilling and spring development. Land and rights-of-way. Does NOT fund irrigation or land drainage. Wastewater treatment systems for rural towns: If your community has aging lagoons, septic systems that are failing, or no centralized sewer system, this is the program. RD also funds solid waste disposal systems. Emergency Community Water Assistance Grants (ECWAG): Separate program for communities facing imminent public health emergency from water system failure. Up to $500,000 for repairs or interim measures. Faster processing than standard WWD applications. How to apply: Contact your USDA Rural Development State Office. They assign a Rural Development specialist to work through the process with you. Applications are accepted year-round; funding is subject to annual appropriations. Pre-application consultation is strongly recommended — RD staff will tell you what documentation you need and whether your project is competitive.
State-Level Water Grant Programs
State programs vary enormously but several of the largest deserve attention for organizations operating in those states. California has some of the most extensive state water grant programs in the country: - Proposition 1 Integrated Regional Water Management (IRWM): $222 million available for regional water projects. Funds planning, storage, recycled water, and flood management through regional coalitions. - Clean Water State Revolving Fund (CWSRF): Low-interest loans with principal forgiveness available. The State Water Board runs an annual application cycle. - Small Community Drinking Water Funding: $50 million program for communities under 3,300 serving disadvantaged areas. Includes grants, not just loans. - Small Community Clean Water/Wastewater Funding: $110 million for communities under 20,000 with median household income below state average. - Floodplain Management and Risk Awareness: $24.3 million available through California DWR for floodplain projects. - San Joaquin River Water Quality: $36.6 million for projects improving water quality in the San Joaquin River watershed. Florida: The CWSRF is the state's largest infrastructure finance program, providing hundreds of millions annually. Priority list applications are accepted through FDEP. Wastewater, stormwater, and nutrient reduction projects all qualify. Texas: The Texas Water Development Board (TWDB) administers multiple programs including the Clean Water SRF, Drinking Water SRF, and the State Water Implementation Fund for Texas (SWIFT). SWIFT is a $2 billion revolving fund that provides low-interest loans for projects in the State Water Plan. Illinois: IEPA administers SRF programs and also has specific programs for lead service line replacement with principal forgiveness for disadvantaged communities, including census-tract-level programs. Pennsylvania: Multiple programs through PENNVEST (Pennsylvania Infrastructure Investment Authority) including drinking water, wastewater, and stormwater loans and grants. Disadvantaged community grants available through the PENNVEST program.
Tribal Water Infrastructure Programs
Tribal governments have access to water funding through both standard federal programs and Tribal-specific channels. EPA Tribal Water Programs: EPA provides direct grants to Tribal governments for water infrastructure planning, construction, and operation through its Indian General Assistance Program (IGAP) and Tribal Clean Water Act programs. The CWSRF and DWSRF both have Tribal Set-Asides in most states, and some states have separate Tribal application tracks. IIJA Tribal provisions: The IIJA included $3.5 billion specifically for Tribal water projects under Section 40910, administered through the Bureau of Indian Affairs. This includes funds for sanitation facilities construction, which the IHS (Indian Health Service) Division of Sanitation Facilities Construction administers. The IHS SFC program builds water and wastewater systems for Tribal communities with severe health needs. USDA RD for Tribes: Tribal governments explicitly qualify for USDA Rural Development Water and Waste Disposal programs. The application process mirrors that for municipalities. RD has Tribal Coordinators in most State Offices. Drinking water on tribal lands: The EPA estimates that about 13% of Tribal homes lack running water or safe drinking water access. The IHS SFC program prioritizes these communities, but the backlog is long. IIJA funding has accelerated project delivery for some tribes.
Water Sector Cybersecurity and Resilience Grants
Water utilities face escalating cybersecurity threats. The 2021 Oldsmar, Florida incident — where an attacker briefly raised sodium hydroxide levels — raised national attention. Congress responded with funding. EPA's Water Sector Cybersecurity Technical Assistance: Under IIJA Section 1551, EPA provides direct technical assistance, not grants. This includes site assessments, incident response planning, and training for utilities that cannot afford commercial cybersecurity services. Utilities apply through EPA Regional Offices. DHS/CISA Water Sector Grants: The Cybersecurity and Infrastructure Security Agency offers grants and technical assistance to critical infrastructure operators including water utilities. The Infrastructure Resilience Planning Framework and the Protective Security Advisor program provide no-cost assessments. WaterISAC: The Water Information Sharing and Analysis Center provides cybersecurity threat information to member utilities at low cost. This is not a grant program, but it is a federally-supported resource worth knowing. FEMA Hazard Mitigation: FEMA's BRIC (Building Resilient Infrastructure and Communities) and HMGP (Hazard Mitigation Grant Program) fund water system resilience projects including backup power, flood protection, and seismic upgrades for utilities in disaster-prone areas. Utilities typically apply through their state emergency management agency.
How to Find and Apply for Water Grants
The funding landscape is fragmented, but the application path follows a consistent logic. For federal SRF funding: Your state environmental or water authority runs the program. Contact them first. Most states have annual priority lists and application deadlines. Many states hold pre-application meetings — attend them. Projects are ranked by criteria including water quality impact, public health need, and affordability. For USDA RD: Contact your state Rural Development office directly. They assign a specialist to walk through eligibility and documentation. Do not submit without a pre-application consultation — it wastes everyone's time. USDA wants to fund eligible projects; they will help you get the application right. For IIJA-specific programs (lead service lines, PFAS): EPA allocates funds to states, and states run application processes. Contact your state drinking water program. For PFAS specifically, states are still building out their programs — check for supplemental DWSRF application windows. For FEMA water resilience: Apply through your state emergency management agency. Projects must be in a FEMA-approved Hazard Mitigation Plan. If your community doesn't have a current plan, start there. Key documentation for most applications: - Engineering feasibility study or preliminary engineering report - Environmental review (NEPA for federal programs) - Financial capacity analysis (especially for loan programs) - Evidence of need — for rural programs, census data, MHI comparisons, system condition reports - For lead service line programs: inventory of lead service lines Timeline: SRF applications often have 6-12 month cycles. USDA RD can take 12-24 months from application to funding obligation for larger projects. Plan ahead. For emergency programs (ECWAG, FEMA), faster timelines are possible when genuine emergency conditions exist.
Common Reasons Water Grant Applications Fail
After reviewing thousands of water infrastructure applications, a pattern emerges in what causes rejections or low rankings. Weak needs documentation. For USDA RD, the needs assessment must demonstrate that the current system poses a health or safety risk, or that the community cannot sustain its existing water supply. Generic statements do not work. Water quality test results, system failure documentation, and health authority letters are required. Missing pre-application steps. Especially for USDA and larger SRF projects, skipping the pre-application consultation leads to incomplete submissions. These programs are relationship-based — the state agency staff knows the program better than any outside consultant. Unrealistic project scope. SRF and USDA programs will fund what the community can realistically manage. Proposing a regional system consolidation for a community that has never operated one creates operational risk that reviewers flag. Build the capacity case alongside the infrastructure case. Ineligible costs included. SRF funds infrastructure, not operations. USDA RD does not fund irrigation. FEMA does not fund routine deferred maintenance. Read the eligible cost lists carefully and break out ineligible items before submitting. Insufficient environmental review. Federal programs require NEPA compliance. Projects with potential impacts to wetlands, floodplains, or historic properties take longer and require additional documentation. Identify these issues early and get your state environmental contact involved. Missed deadlines on priority list cycles. SRF programs have fixed application windows. If you miss the cycle, you wait a year. Set calendar reminders 90 days before the application window opens.
Amounts and Timelines to Plan Around
Federal program funding levels for FY2026 and near-term outlook: CWSRF: Total national capitalization approximately $1.7 billion annually (regular IIJA supplemental). Plus remaining IIJA supplemental funds being disbursed through 2026. Total program lending nationally exceeds $10 billion annually when including state matches and revolving loan repayments. DWSRF: Similar scale. Lead service line supplemental allocation: $3 billion remaining through FY2026. PFAS emerging contaminants: approximately $800 million remaining in the pipeline. USDA Water and Waste Disposal: FY2025 appropriation approximately $570 million (loans and grants combined). Grant-to-loan ratio depends on community income levels. Small communities typically receive 25-75% grant funding. IIJA status: The IIJA authorization period runs through FY2026. States are working to obligate remaining funds before the authorization window closes. This creates a near-term opportunity — states want to move money. If you have a project ready to go, now is the time to apply. California-specific timelines: DWR programs like IRWM and Small Community Funding have specific solicitation windows. The 2025-26 cycles are underway. Check DWR's website for current open solicitations. Funding mix reality: Most water infrastructure projects piece together funding from multiple sources — a USDA RD loan with a grant component, a state SRF loan, and possibly a CDBG grant for utility connection costs. Plan for a 12-36 month funding assembly process for large projects.
