The Safe Drinking Water Act of 1974 was passed in order to protect public health by setting standards for drinking water water quality.  The Drinking Water State Revolving Fund was authorized in 1997. The primary focus of the program is to assist communities in achieving the standards for water treatment set forth in the Safe Drinking Water Act.  A total of approximately $294 million of projects have been financed with the proceeds of bonds or direct loans issued to date. The Drinking Water Program is administered similarly to the Clean Water Program, except that it typically funds the following four types of projects: treatment filtration construction and upgrade, transmission pipeline construction, storage and new source development.   The current program continues to apply over 75% of available funds for treatment plant construction or upgrade, with 10% of the funds used for small systems.  The Drinking Water Program also funds a variety of set-aside initiatives. Some of these initiatives include: capacity development (to enable system operators to maintain compliance with requirements of the Safe Drinking Water Act); wellhead protection assessments; source water delineation and technical assistance for small systems.
