Community Drinking Water Infrastructure Sustainability Act; enact.

SB 2311, the Community Drinking Water Infrastructure Sustainability Act, creates a standardized letter grading system (A-F) for Mississippi's community public water systems - those serving at least 15 year-round connections. The Mississippi State Board of Health will assign grades annually based on criteria including water quality violation history, financial stability, infrastructure condition, and customer satisfaction. Water systems must notify customers of their grade within 30 days of the Board's public report, which will be published online starting January 1, 2028. This law directly affects over 300 community water systems across Mississippi, aiming to improve transparency and accountability in drinking water safety.
