How to Apply for State Revolving Fund Loans for Infrastructure Projects
State Revolving Fund loans can provide long-term, relatively low-cost financing for drinking water and wastewater infrastructure in California. Agencies use these programs to fund treatment upgrades, collection systems, recycled water facilities, energy improvements, resilience projects, and other capital investments that protect public health and water quality.
For water and wastewater professionals in the Los Angeles Basin, the application process involves more than completing a financing form. A successful request connects a clearly defined project with regulatory compliance, environmental review, technical readiness, reliable revenue, and the priorities established by the California State Water Resources Control Board.
Understanding the process early helps agencies avoid delays. It also gives engineers, operators, consultants, and finance staff time to coordinate documentation before a project reaches the funding queue.
Identify the right revolving fund program
The Clean Water State Revolving Fund, commonly called the CWSRF, supports wastewater and water-quality projects. Eligible work may include publicly owned treatment works, sewer rehabilitation, stormwater management, nonpoint-source pollution controls, water reuse, and decentralized wastewater systems. The Drinking Water State Revolving Fund, or DWSRF, is designed for public water systems and certain nonprofit noncommunity systems that need to address health risks, compliance obligations, capacity limitations, or aging assets.
The California State Water Resources Control Board administers both programs through its Division of Financial Assistance. Each program operates under an Intended Use Plan that describes priorities, eligibility standards, available funds, and procedures for ranking projects. Reviewing the current plan is an essential first step because funding categories and submission requirements can change from year to year.
A project that appears eligible may still need to compete with other requests. Health protection, regulatory compliance, disadvantaged community status, readiness to proceed, and environmental benefits can influence prioritization. Agencies should identify which benefits are strongest and document them consistently throughout the application.
Define the project and establish readiness
A strong application begins with a precise project description. Explain the existing problem, the assets affected, the proposed solution, the expected useful life, and the consequences of postponing the work. Include planning-level cost estimates, construction schedules, financing needs, and the population or service area that will benefit.
Applicants should distinguish between planning, design, and construction costs. Some preliminary activities may qualify for financing, while others may require separate funding or approval. A basis-of-design report, asset condition assessment, preliminary engineering report, or facilities plan can help demonstrate that the proposed scope is technically reasonable.
Readiness matters because revolving fund programs generally prioritize projects that can move efficiently through review and construction. Agencies should secure governing-board authorization, identify the project manager, confirm property or easement needs, and begin procurement planning. If multiple projects are bundled, explain how the components relate and why they should be financed together.
The financial plan should account for inflation, contingencies, engineering, legal services, construction management, environmental work, and potential changes in scope. Underestimating total project cost can create a funding gap later, while an unsupported estimate can weaken the application.
Assemble compliance and environmental documentation
Regulatory compliance is central to the review. Wastewater applicants should explain how the project relates to discharge permit requirements, enforcement obligations, water-quality standards, or a documented need to improve treatment performance. Agencies preparing for a permit action can use resources on the NPDES permit process to connect financing plans with compliance schedules and operational requirements.
Environmental review may involve the California Environmental Quality Act, federal environmental requirements, cultural resources, biological resources, air quality, climate impacts, and historic properties. The exact documentation depends on the project and its funding pathway. Beginning this work early is valuable because environmental clearance can become a critical-path item.
Applicants should maintain a clear record of permits, technical studies, public notices, consultation, and mitigation measures. Missing or inconsistent information can lead to requests for clarification and delay a funding agreement. A single document control system helps project teams track versions and preserve supporting evidence.
The application should also address climate resilience and greenhouse-gas considerations where relevant. Flood exposure, wildfire risk, sea-level rise, drought, seismic hazards, backup power, energy efficiency, and cybersecurity may affect the project’s long-term value. These factors can strengthen the case for modernization when they are tied to specific design decisions.
Compare project costs and financing terms
A revolving fund loan usually offers a long repayment period and an interest rate that may be more favorable than conventional borrowing. However, the total cost depends on the approved amount, term, interest rate, fees, reserves, local contribution, and the timing of reimbursements. The applicant should model debt service against projected revenues and existing obligations.
Financial capacity review commonly includes audited financial statements, budgets, rate studies, debt schedules, reserve policies, population or customer projections, and evidence of governing-body approval. A utility should demonstrate how it will repay the loan without compromising operations, maintenance, regulatory compliance, or other essential capital work.
Project alternatives should be evaluated using lifecycle cost, reliability, energy use, staffing needs, chemical consumption, residuals management, and future expansion. For treatment facilities, an assessment of sludge thermal hydrolysis can help frame whether an advanced solids-processing investment produces enough operational and environmental value to justify its cost.
| Financing pathway | Typical project focus | Important evidence | Key consideration |
|---|---|---|---|
| CWSRF loan | Wastewater, water quality, reuse, and stormwater | Facilities planning, permits, environmental review, cost estimate | Show measurable water-quality or public-health benefits |
| DWSRF loan | Drinking water treatment, distribution, storage, and source protection | Public water system information, compliance records, engineering documents | Address health risk, reliability, capacity, or regulatory need |
| Principal forgiveness or subsidies | Eligible projects serving qualifying communities | Income, affordability, and disadvantaged-community documentation | Availability depends on program rules and annual priorities |
| Refinancing or supplemental financing | Existing eligible debt or cost increases | Original project records, debt documents, updated financial analysis | Confirm eligibility before restructuring commitments |
Terms and subsidy structures vary, so agencies should avoid assuming that a preliminary estimate represents the final offer. The State Water Board will determine the applicable terms after reviewing eligibility, priority, available appropriations, and financial capacity.
Complete the application through the state process
California applicants generally begin through the Financial Assistance Application Submittal Tool, known as FAAST, or through the current process identified by the State Water Board. The submission commonly includes organizational information, project scope, estimated costs, schedule, environmental status, permits, financing information, and supporting technical documents.
The application should use consistent numbers throughout. The amount in the project description, engineering estimate, governing-board resolution, financial model, and funding request should match or be clearly reconciled. Any assumptions about inflation, escalation, contingencies, grants, local funds, or other borrowing should be explained.
After submission, state reviewers may request revisions or additional records. Treat these requests as part of the technical review rather than as an administrative afterthought. Assign an owner to each response, keep a deadline log, and submit complete answers in a single organized package whenever possible.
Once a project is approved, the applicant may need to execute a financial agreement, satisfy special conditions, complete environmental requirements, and follow approved procurement and reimbursement procedures. Costs incurred before authorization may not be eligible, so project managers should confirm the rules before issuing contracts or beginning construction.
Coordinate the people who will deliver the project
SRF applications cross organizational boundaries. Engineering staff define the solution, operators explain performance and maintainability, finance teams demonstrate repayment capacity, legal counsel reviews commitments, and governing bodies authorize the transaction. A designated coordinator should manage the schedule and make sure each discipline’s information supports the same project narrative.
Operators should be involved before design is finalized. Their experience can identify access limitations, maintenance risks, staffing requirements, process-control needs, and construction phasing issues that may not appear in a planning document. Automation and controls specialists can also help quantify improvements in monitoring, energy management, alarm response, and data quality.
Professional networks can make this coordination easier. The LABS leadership history reflects the range of water professionals who have contributed to the Los Angeles Basin Section over time, and its technical programs offer useful settings for exchanging practical perspectives on project delivery, operations, and compliance.
A concise internal checklist should track eligibility, project ranking, environmental review, permits, cost estimates, financial documents, board action, application submission, reviewer comments, and agreement conditions. This record supports continuity when staff or consultants change and provides an audit trail for the agency.
Recommendations for a stronger application
- Review the current CWSRF or DWSRF Intended Use Plan before selecting the financing strategy.
- Prepare a defensible planning-level estimate with escalation, contingency, design, construction management, and environmental costs.
- Connect the project to a specific compliance obligation, public-health risk, resilience objective, or water-quality benefit.
- Involve operators, finance staff, legal counsel, and governing-board representatives during early project development.
- Create a document register and response calendar for the FAAST submission and state review.
A well-prepared SRF request gives reviewers a clear reason to fund the project, a credible plan for completing it, and confidence that the agency can repay and operate the resulting asset. Begin with the current State Water Board requirements, organize the technical and financial record, and use professional training and peer networks to strengthen the application before submission. Engage LABS of CWEA through its educational and professional programs to connect with the expertise needed to move essential water infrastructure from concept to construction.
