Electronics Repair for Water & Wastewater Utilities
Municipal plants run some of the oldest control systems in industry — SLC 500s, PLC-5s, and operator interfaces bought before the century turned. When procurement rules make replacements slow and budgets make retrofits rare, repairing the installed unit is the practical path.
