Water Protection Financial Assistance Center

The Financial Assistance Center is dedicated to helping communities plan, finance and build water infrastructure projects that improve the lives of Missourians. Through the Clean Water State Revolving Fund, Drinking Water State Revolving Fund and state programs, the center provides technical and financial assistance to applicants for projects including construction of new drinking water or wastewater infrastructure, existing infrastructure upgrades or rehabilitation; storm water-related projects that benefit water quality; and green infrastructure. 

State Revolving Fund

The State Revolving Funds (SRF) provide low-interest loans for wastewater and drinking water infrastructure projects. The U.S. Environmental Protection Agency provides grants or "seed money" with a required 20% state match, to capitalize state revolving funds with which the states provide low-interest loans to communities. As loan principal and interest payments are paid back into the fund, the money is used to finance new loan projects. Projects may be new construction or the improvement or renovation of existing facilities.

  • The Clean Water SRF funds wastewater treatment, sewer rehabilitation, and stormwater quality improvements, as well as non-point source projects.
  • The Drinking Water SRF funds water treatment plants or improvements to existing facilities, distribution, water storage facilities, wells, and interconnection/consolidation.

State Loans and Grants

The Financial Assistance Center and Public Drinking Water Branch offer several other grant and loan programs, including Small Borrower loans and planning grants.
