A state revolving fund (SRF) is a loan program that is capitalized by federal grants, state appropriations and dedicated revenues. Congress established the SRF program to provide states with a way to offer financial assistance to local communities. The program is a federal-state partnership, with the state being responsible for operating their program. This gives the states the flexibility to fund a range of projects that address their highest priority needs to protect public health, protect the environment and meet environmental standards benefiting hundreds of millions of people.

SRF programs function like environmental infrastructure banks, by providing low interest loans to eligible recipients for eligible projects. As loans are repaid, the loan principal and interest earnings are recycled back into the fund. The states use those funds to finance new loans to other recipients, allowing the funds to "revolve" at the state level. The funds can also be used to provide additional subsidization allocations, such as grants. 

Missouri currently has two SRF programs - Clean Water State Revolving Fund and Drinking Water State Revolving Fund. These programs provide low-cost financing for a wide range of drinking water and wastewater infrastructure projects. Since their inception, the programs have provided more than $3.8 billion dollars in grants and loans to hundreds of communities, including over $175 million in grants. The programs have saved borrowers more than $1.4 billion in interest savings. Each program is briefly described below, with links to more information.

Clean Water State Revolving Fund

The Clean Water State Revolving Fund (CWSRF) program was created by the 1987 amendments to the Clean Water Act (CWA) and amended in 2014 by the Water Resources Reform and Development Act. The Missouri CWSRF program is a federal-state partnership between the U.S. Environmental Protection Agency (EPA) and the state of Missouri, with the state being responsible for operating the program. 

Missouri applies to EPA annually for a base capitalization grant or "seed money" to fund its CWSRF program. Using a combination of 80% federal grant funds and 20% state matching funds, the Missouri CWSRF program provides low-interest loans and grants to Missouri communities. This funding may be used for a wide range of wastewater infrastructure and nonpoint source pollution control projects, such as wastewater treatment, sewer rehabilitation and stormwater improvements. Funding is typically offered through a competitive, annual funding cycle. More information about each loan and grant, including eligible applicants, eligible projects and how to apply, is provided at the links below.

The Missouri CWSRF fund is managed by the Missouri Department of Natural Resources through its Financial Assistance Center, with oversight from the Clean Water Commission. The CWSRF Stakeholder Workgroup provides input on the department’s CWSRF planning and policy related to grant funding. To learn more about specific projects, visit the CWSRF success stories below.

Drinking Water State Revolving Fund

The Drinking Water State Revolving Loan Fund (DWSRF) program was created by the 1996 amendments to the Safe Drinking Water Act (SDWA). The Missouri DWSRF program is a federal-state partnership between the U.S. Environmental Protection Agency (EPA) and the state of Missouri, with the state being responsible for operating the program.

Missouri applies to EPA annually for a base capitalization grant or "seed money" to fund its DWSRF program. Using a combination of 80% federal grant funds and 20% state matching funds, the Missouri DWSRF program provides low-interest loans and grants to Missouri communities. This funding may be used for a wide range of drinking water infrastructure projects, such as water treatment and distribution, water storage facilities, wells and interconnection/ consolidation. Funding is typically offered through a competitive, annual funding cycle. More information about each loan and grant, including eligible applicants, eligible projects and how to apply, is provided at the links below.
