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.

Fixed — or it's free

Unrepairable units are refunded; evaluations cost $0

24-month warranty

Every repair covered, parts and labor

3–5 business days bench time

Rush (1–2 day) and emergency service available

Program preserved

Your application and settings stay in the unit

Equipment we repair for water & wastewater

  • SLC 500 / PLC-5 era power supplies & I/O
  • Operator interface terminals
  • VFDs on pumps and blowers (≤25 HP)
  • Panel power supplies

Why it matters here

  • Decades-old hardware with no OEM path
  • Public procurement makes emergency replacements slow
  • SCADA migrations are multi-year projects; repairs are same-week
