MS Emergency Drinking Water Network Act; create.

HB 849 establishes Mississippi's Emergency Drinking Water Network Act, administered by the Mississippi Emergency Management Agency (MEMA). It creates a grant program using American Rescue Plan Act (ARPA) funds to equip rural water systems and first responders with equipment and training for maintaining drinking water access during infrastructure failures. Key provisions include funding for potable water distribution points, transport trucks, relocatable pump systems, and training for water operators. The program requires projects to be completed by December 31, 2026, or the federal ARPA deadline, with recipients certifying project completion using other funds if deadlines pass.
