State Revolving Fund wastewater and drinking water loans and grants

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 nonpoint source projects
  • The Drinking Water SRF funds water treatment plants or improvements to existing facilities, distribution, water storage facilities, wells and interconnection/consolidation

Since inception in 1987, the State Revolving Funds have provided more than $3.5 billion dollars in grants and loans to hundreds of communities, including over $150 million in grants. The SRF program provides loans at only 30% of the market rate for borrowers, and has saved borrowers more than $1.1 billion in interest savings. Over the next 20 years, the drinking water and wastewater infrastructure needs in Missouri are estimated to exceed $18 billion.
