Rockwell Automation Showcases AI-Driven Water Solutions at WEFTEC 2026

Rockwell Automation presents an expanded suite of industrial automation, machine learning controllers, and operational security architectures engineered for municipal water and wastewater treatment facilities, focusing on scalable process optimization and cybersecurity compliance across distributed utility networks.

Unified Process Control and Edge Analytics
Modern water utilities face stringent water quality mandates, fluctuating biological and hydraulic influent loads, and increasing energy expenditures associated with aeration, pumping, and chemical treatment stages. Process optimization in these facilities requires low-latency data ingestion directly at the supervisory control layer. Rockwell Automation features its CompactLogix 5480 controller, an industrial automation platform that embeds an edge computing engine alongside commercial real-time control execution.

By executing machine learning models directly on the controller, the system evaluates real-time hydraulic pressures, dissolved oxygen thresholds, and chemical feed rates without introducing telemetry lag from off-site cloud connections. This capability allows plant operations to execute predictive dosing routines and dynamic flow modulation, reducing over-treatment and secondary energy usage while maintaining compliance margins.

Standardized Software Libraries for Desalination Infrastructure
Reverse osmosis processes, including seawater and brine treatment, represent highly energy-intensive stages within modern utility frameworks. High-pressure pump trains and energy recovery devices require precise stage sequencing to prevent membrane fouling and hydraulic shock. Rockwell Automation introduces a dedicated desalination process control solution standard engineered around modular, pre-tested software libraries.

The standardized library architecture integrates directly with the company's broader process control environment. By providing pre-validated logic blocks and human-machine interface elements, the system reduces software engineering cycles, lowers commissioning risks during brownfield retrofits, and establishes uniform instrumentation interfaces across both high-pressure seawater reverse osmosis and brackish water recovery facilities.

Critical Infrastructure Cybersecurity and Architectural Integration
Utility modernization initiatives expand attack surfaces as legacy operational networks connect to enterprise digital management systems. Demonstrations at booth 1317 during WEFTEC 2026, held from September 26 to 30 in New Orleans, focus on aligning water operations with the National Institute of Standards and Technology Cybersecurity Framework (NIST CSF).

The operational security framework incorporates layered network segmentation, secure role-based access management, and encrypted field protocols. Open automation methodologies allow water authorities to interconnect disparate lift stations, well fields, and centralized treatment facilities into a consolidated supervisory platform. Unifying operational technology with motor control centers and power distribution feeds provides centralized visibility, assisting operators in identifying hardware anomalies, balancing power draw, and preserving grid resilience during peak demand intervals.

Process automation architectures for water, wastewater, and membrane-based desalination operate within a competitive field led by Rockwell Automation, Siemens with its Simatic PCS 7 and PCS neo platforms, Schneider Electric utilizing EcoStruxure for Water and Wastewater, and ABB featuring ABB Ability Symphony Plus.

In desalination automation, control platforms compete primarily on software modularity, standard library availability, and integration with energy recovery devices such as isobaric pressure exchangers. Siemens addresses seawater reverse osmosis through standardized libraries for TIA Portal and PCS 7, focusing on high-speed fieldbus synchronization (Profinet IRT) to coordinate variable frequency drives on multi-stage high-pressure pumps. Schneider Electric deploys EcoStruxure Process Expert, utilizing tested and validated architectures that combine power monitoring via PowerLogic hardware with process control logic to benchmark kilowatt-hours per cubic meter treated.

The Rockwell Automation approach relies on its Logix control platform and PlantPAx system libraries certified to the IEC 62443-4-2 cybersecurity standard for industrial automation components. By utilizing the CompactLogix 5480, Rockwell embeds a commercial operating system running alongside the Logix control engine on a single hardware chassis. In contrast to conventional arrangements from ABB or Schneider Electric that typically deploy external industrial personal computers (IPCs) or network gateways to process high-throughput predictive algorithms, this dual-engine architecture executes artificial intelligence inferencing directly across the internal backplane. This reduces system footprint in compact remote telemetry units and pumping stations while mitigating external communication vulnerability vectors.
