Frequently Asked Questions

Common questions about our water treatment automation solutions.

What types of water treatment plants do you automate?
SENTRADO automates all types of water treatment facilities including raw water intake stations, drinking water treatment plants, industrial process water systems, wastewater treatment plants, and water distribution pumping stations. Our solutions cover the complete water treatment cycle from source to discharge.
Can you retrofit existing water plants?
Yes, we specialize in both greenfield projects and retrofitting existing water treatment facilities. Our retrofit solutions include upgrading legacy PLC systems, adding SCADA monitoring, installing VFDs on existing pumps, and integrating new instrumentation — all with minimal disruption to ongoing operations.
Do you provide remote monitoring services?
Yes, our SCADA systems include comprehensive remote monitoring capabilities via web browsers and mobile apps. We provide 24/7 alarm management, real-time data visualization, historical trend analysis, and remote control functions. Our cloud-based monitoring platform enables operators to manage multiple water facilities from a single dashboard.
What PLC platforms are used in water treatment?
We primarily use Siemens S7-1500 and S7-1200 PLCs for water treatment applications due to their reliability and water-industry-specific function blocks. We also work with Allen-Bradley CompactLogix/ControlLogix for projects requiring Rockwell platforms. All systems support standard protocols including PROFINET, Modbus TCP, and OPC UA.
How do you ensure water quality compliance?
Our automation systems integrate inline water quality instruments (pH, turbidity, dissolved oxygen, chlorine residual) with automatic dosing control. All data is logged and reported in compliance with local water quality standards. We implement redundant measurement systems, automatic calibration routines, and fail-safe controls to ensure continuous compliance.
