Water & Wastewater Treatment Electronics Repair
Reliable electronics repair for India's water infrastructure — VFD pump drives, PLC and SCADA controllers, level and flow transmitter boards, dosing pump controllers, and UV/ozone system electronics for municipal, ETP, STP, and desalination plants.
Water treatment downtime risks public health and regulatory penalties. Synchronics repairs VFD pump drives, PLC/SCADA controllers, and transmitter boards at the component level — keeping your treatment plant running around the clock.
Water and wastewater treatment plants depend on a complex network of VFDs, PLCs, SCADA systems, and instrumentation to maintain continuous, compliant operations. Corrosive gases like hydrogen sulphide, high ambient humidity, chemical exposure from dosing systems, and constant 24/7 duty cycles push electronics to their limits. Synchronics has 32+ years of experience repairing the drives, controllers, and transmitter boards that keep India's municipal water supply, effluent treatment, sewage treatment, desalination, and pumping stations operational — from compact dosing pump controllers to 500kW raw water intake pump drives.
Diagnosis Guide
Common Water & Wastewater Treatment Electronics Problems We Fix
Experiencing any of these symptoms? Our engineers have diagnosed and repaired thousands of these faults.
VFD IGBT Failure on Pump Drive
Pump drive trips on overcurrent, output phase missing, motor stalls or runs erratically
IGBT degradation from continuous duty, power surge from grid instability, DC bus capacitor ageing
PLC Communication Loss
SCADA shows offline, remote pump stations unreachable, no telemetry data, alarm flood
Communication module failure from humidity ingress, Profibus/Modbus transceiver damage, power supply degradation
Transmitter Drift / No Signal
Level or flow reading drifts, 4-20mA output pegged at 0 or full scale, dosing inaccurate
Sensor board corrosion from H2S exposure, ADC failure, power regulator damage from lightning transients
Soft Starter Thyristor Failure
Large pump motor fails to start, bypass contactor does not engage, overcurrent at startup
SCR gate driver circuit failure, thyristor degradation from frequent starts, cooling fan failure
UV System Ballast Failure
UV lamps not firing, disinfection dose alarm, treated water non-compliant
Ballast driver MOSFET failure, capacitor dry-out from heat, control board corrosion
Dosing Pump Controller Fault
Chemical dosing stops, pH or chlorine out of spec, manual dosing required
Stepper motor driver failure, membrane switch degradation, display board corrosion from chemical fumes
How It Works
Our Water Treatment Electronics Repair Process
A systematic, schematic-driven repair process — from receipt to dispatch.
Priority Intake & Logging
Water treatment repairs are treated as priority given the public health implications. Unit logged immediately, photographed, and assigned to a specialist engineer familiar with water industry equipment.
Corrosion Assessment & Cleaning
Units from treatment plants are inspected for H2S corrosion, chemical residue, and moisture damage. Ultrasonic cleaning and conformal coating removal performed before diagnosis.
Component-Level Diagnosis
Full functional test including IGBT characterisation for drives, communication protocol verification for PLCs, and 4-20mA loop calibration for transmitter boards. Root cause documented.
Precision Repair
Failed components replaced with genuine or equivalent-grade parts. Conformal coating reapplied for humidity protection. Drive parameters backed up and restored.
Load & Endurance Test
Drives tested at rated current with motor load. PLCs tested for communication integrity. Transmitter boards calibrated against reference standards. 24-hour burn-in for critical units.
Report, Warranty & Dispatch
6-month warranty certificate, detailed service report, and re-commissioning notes issued. Units packed with anti-corrosion protection for transit.
Thorough Inspection
What We Inspect in Every Water Treatment Unit
Every unit goes through a comprehensive inspection checklist before and after repair.

Troubleshooting
Common Water Treatment Drive & Controller Faults We Resolve
Seeing one of these error codes? We diagnose and repair the root cause.
Overcurrent or short-circuit trip on pump drive
IGBT failure, motor winding fault, cable insulation breakdown in wet environment
DC bus overvoltage or undervoltage on VFD
Capacitor bank degradation, input power fluctuation, braking resistor open circuit
Communication loss between PLC and SCADA or remote I/O
Profibus/Modbus transceiver failure, cable corrosion, communication module firmware error
4-20mA transmitter output at 0mA or 22mA fault signal
Sensor board corrosion, lightning surge damage, ADC chip failure, cable water ingress
UV disinfection system lamp not igniting or low dose alarm
Ballast driver board failure, MOSFET or capacitor failure in inverter stage
Thermal overload trip on soft starter during pump start
SCR not fully conducting (half-wave output), cooling fan seized, ambient temperature high
Water treatment electronics faults are often compounded by environmental factors — humidity, H2S, chemical exposure, and lightning. Share your unit type, fault code, and plant conditions for expert diagnosis.
