The U.S. Environmental Protection Agency (EPA) announced a $281 million Water Infrastructure Finance and Innovation Act (WIFIA) loan to Johnson County, Kansas to support the Nelson Wastewater Treatment Facility Improvements Project. Through this WIFIA loan, EPA is supporting the modernization of critical wastewater facilities to address aged and deteriorating Infrastructure and to comply with new regulatory requirements. Johnson County Wastewater pursued the WIFIA loan because of favorable interest rates and repayment terms, which will help to reduce impacts on future sewer rates.
