These loans come from the State Revolving Fund program. The State Revolving Fund finances the design and construction of Colorado water, wastewater, and stormwater infrastructure. We administer the fund along with the Department of Local Affairs, and the Colorado Water Resources & Power Development Authority.

We manage environmental reviews, engineering design approvals, and conduct overall project management. The power authority manages the finances and loan approvals. Local affairs staff members work with applicants on credit reviews and reports.

The 2026 eligibility survey will open on May 1, 2025 Submission deadline is June 30, 2025 The eligibility survey is used to identify the 20-year capital improvement needs of all publicly owned water and sewer systems, private nonprofit water systems, publicly owned stormwater systems, and non-point source projects throughout Colorado.

We issue the annual eligibility survey process through an online platform, the Colorado Environmental Online Services (CEOS). Eligible entities on this system receive a notification to fill out the survey. You cannot receive this funding unless you participate in the eligibility survey.

This survey is the first step in the State Revolving Fund application process. The survey is not an application, and completing it does not require that you apply for financial assistance. When the survey is complete, your system’s infrastructure needs will be identified and included in Appendix A Project Eligibility List of the below Intended Use Plans.

The plans are updated annually and are effective from January through December. Entities seeking funding for their water and sewer projects must be included on the applicable list prior to applying for funding. All forms are processed using Colorado Environmental Online Services (CEOS) .

New users will first need to create their CEOS user account before accessing the survey. If you are new to CEOS, please review the below instructions for helpful tips on account setup. Create your CEOS user account.

Responsible Officials (RO): managing consultants and preparers. After submitting your forms, check for confirmation that the form was received using the spreadsheet link below. Submittal confirmation report .

The intended use plan (often referred to as the IUP) outlines a framework for using the funds, financing water quality infrastructure projects, and supporting related program activities during the calendar year. The IUP summarizes the results of the eligibility survey.

Additional loan information State environmental review process All proposed actions funded by the State Revolving Fund program must undergo an environmental review process to assess compliance with the intent of the National Environmental Policy Act (NEPA) and State Review Process (SERP).

The State, borrower, engineer, contractor, and subcontractors must cooperate fully with federal and local governments and all other concerned public and private organizations, to use all practical means and measures including financial and technical assistance, and to create and maintain conditions under which man and nature can exist in productive harmony and promote the general welfare of the public.

The purpose of the environmental review is to evaluate the relevant environmental impacts and impact to the human environment of a federal action. The environmental review process includes one of three levels of review: Categorical Exclusion (CatEx). Environmental Assessment/Finding of No Significant Impact (EA/FNSI).

Environmental Impact Statement/Record of Decision (EIS/ROD). SRF Environmental Review Process. Environment forms and guidance Environmental assessment template and agency contact list.

Entities meet one of the three data scenarios that test primary factors and, if necessary, secondary factors for determining disadvantaged communities. Factors are found in the Defining Disadvantaged Communities document. Funds requested to form a special district should be included in the pre-qualification form.

State revolving fund design and engineering grant Design and engineering grant applicants will be considered with project needs assessment submissions and awarded to disadvantaged communities. Design and engineering grant amounts depend on the size and need of a project. The grants assist with costs associated with eligible design expenditures.

Up to 80 percent of the grant can be reimbursed before receiving the SRF loan application. The final 20 percent will be reimbursed upon SRF loan execution. Applicant must be a government entity.
