The bill establishes a Time-Based Water Softener Replacement Program aimed at replacing outdated time-based ion exchange water softeners with more efficient demand-based models. It defines key terms such as "contractor," "eligible replacement," and "rebate," and outlines the criteria for eligible replacements, which must be installed by licensed contractors between July 1, 2025, and June 30, 2027. The program will provide a rebate of $200 to property owners or lessees who make these eligible replacements, with specific requirements for rebate applications, including details about the equipment and its installation.

Additionally, the bill appropriates funds from the general fund to the commissioner of the Pollution Control Agency to facilitate the rebate program, with a specified amount for fiscal year 2026. This appropriation is a one-time allocation that will remain available until June 30, 2028. The legislation aims to promote environmental sustainability by encouraging the use of more efficient water softening technology.
