A complete controls upgrade for the potable water booster system servicing a major hospital facility — Mitsubishi PLC, Beijer X2 Pro HMI, cascade pressure control and intelligent duty rotation across an eight-pump booster bank.
The potable water booster system servicing a major hospital facility was experiencing unstable pressure control across varying site demand conditions. The existing system struggled to maintain consistent discharge pressure, with pumps continuously hunting around setpoint and operating inefficiently under fluctuating loads.
Run hours across the eight-pump booster bank had also become uneven, creating maintenance imbalance and increasing wear on specific units.
Operational visibility was limited, with no central interface providing operators or maintenance personnel with a clear understanding of system status, pump sequencing, alarms or performance trends. Remote monitoring capability was also limited, reducing response time to faults and critical events.
The site required a modernised control solution capable of delivering stable pressure regulation, intelligent pump staging and improved operational visibility suitable for critical hospital infrastructure.
Goto Engineering delivered a complete controls upgrade for the potable water booster system — redesigning the control philosophy, upgrading the automation hardware and implementing a modern operator interface and remote monitoring platform.
The system was rebuilt around a Mitsubishi PLC platform paired with a Beijer X2 Pro HMI, providing operators with a clean, intuitive interface for monitoring system performance, pump operation and alarm conditions.
Advanced cascade control was implemented across the booster bank to maintain stable discharge pressure while ensuring pumps operated within their most efficient performance range. Intelligent duty rotation logic was also developed to evenly distribute run hours across all eight pumps, improving equipment longevity and simplifying maintenance scheduling.
The upgrade also included structured control panel design, improved power distribution architecture and remote SCADA connectivity for alarm visibility and operational support.
The upgraded booster system now delivers stable and responsive pressure control across changing hospital demand conditions, significantly reducing pump hunting and improving overall system efficiency.
Pump utilisation is now automatically balanced across the entire booster bank, helping extend equipment life and improve maintenance planning.
Operators and maintenance personnel now have clear visibility of system operation through the new HMI and remote monitoring platform, with improved alarm management and faster fault response capability.
The result is a modern, maintainable and operationally robust booster control system designed to support the reliability requirements of critical hospital infrastructure.
