A Statewide Resource for Water and Sewer Financing

The success of communities is vitally important to our quality of life in South Carolina. One way to build stronger communities is to invest in infrastructure that is capable of supporting homes, schools and businesses. Infrastructure refers to water and waste water systems as well as storm water drainage and other public facilities. 

Access to basic infrastructure is essential for growth and economic development. Communities can ensure that existing facilities will meet appropriate environmental and health standards as well as prepare for the future by upgrading, improving and expanding their infrastructure capacity. Such investments will help maintain the quality of life for residents and open the door to new opportunities. 

The SC Rural Infrastructure Authority (RIA) was created to help communities with financing for qualified infrastructure projects. Competitive grants are offered to assist in the development of reliable infrastructure that protects public health, addresses environmental quality standards and encourages economic growth.

Low interest loan financing is also available for a variety of infrastructure improvements through the State Revolving Funds. The Office of Local Government (OLG) is responsible for the financial functions of the Drinking Water and Clean Water State Revolving Fund Programs. The OLG (formerly with the SC Budget and Control Board) was transferred to the RIA as a result of the Restructuring Act of 2014. 

These programs offer multiple options for financing critical community infrastructure improvements that will help maintain a safe and healthy environment for residents and contribute to a more sustainable future.


While local, state and federal authorities work towards recovering from the historic flooding in October 2015, rebuilding and restoring the infrastructure that residents and businesses rely on has become an even higher priority.  Several resources continue to be available including FEMA, Small Business Administration and SC Emergency Management Division.  In addition, the Basic Infrastructure grant offered by the RIA is designed to assist communities with improvement of water or sewer infrastructure and if projects require immediate action, they may be submitted as an emergency application.
