The Wastewater and Drinking Water loan programs provide low-interest loans through the State Revolving Fund (SRF). The SRF includes two loan programs: the Water Pollution Control Loan Program (WPCLP) which funds both wastewater and storm water projects, and the Public Water Supply Loan Program (PWSLP) for drinking water projects. These loan programs are both managed by the Illinois Environmental Protection Agency. These programs are commonly referred to federally as “The Clean Water State Revolving Fund” and the “Drinking Water State Revolving Fund.” These programs are annually the recipients of federal capitalization funding which is combined with state matching funds, interest earnings, repayment money, and the sale of bonds to form a source of financing for infrastructure projects. The term “Revolving Fund” means that interest earned, and money repaid, is put back into the program to fund additional projects.
The programs provide financial assistance to eligible public or private applicants for the design and construction of a wide variety of projects that protect or improve the quality of Illinois’ water resources. They assist applicants with projects that address human health and failing water infrastructure. Eligible projects include new drinking water or wastewater infrastructure construction; upgrading or rehabilitating existing infrastructure; storm water-related projects that benefit water quality; and a variety of other projects that protect or improve the quality of Illinois’s rivers, streams, and lakes.
