This bill reauthorizes a federal grant program that helps schools replace aging drinking water fountains and related water infrastructure. The legislation amends the Safe Drinking Water Act to extend the drinking water fountain replacement program for schools through fiscal years 2027 to 2029, and increases annual funding from $5 million to $7 million per year. The bill primarily affects public schools across the country that rely on this federal assistance to upgrade their water systems and ensure students have access to safe drinking water. The increased funding provides schools with additional resources to address water quality concerns and replace outdated or contaminated equipment.
