The purpose of this legislation, known as the "Financing Lead Out of Water Act of 2025" or the "Flow Act," is to improve public health by facilitating the replacement of lead service lines in water systems. Lead service lines can pose serious health risks, particularly to children, and this act aims to make it easier for public water systems to replace these lines by modifying certain financial regulations. One of the key provisions of this act is the modification of the private business use requirements for bonds issued specifically for lead service line replacement projects.
