Project
Control System Modernization and Expansion for a Municipal Water Facility
A municipal water and wastewater treatment facility in Kelowna, British Columbia required a control system modernization that would both stabilize current operations and support future expansion. The project involved migrating from a legacy iFIX HMI environment to APACS+ OS, while also preparing the facility for a dual-leg Siemens SIMATIC S7 automation system to operate alongside APACS+.
Turn-Key Controls delivered a phased modernization strategy that maintained operational continuity while positioning the plant for future growth, redundancy, and long-term support.
Technical Highlights
Legacy System: iFIX HMI
Modernized Platform: APACS+ OS
Expanded Automation: Dual-leg Siemens SIMATIC S7 system
Architecture: Parallel control platforms with planned integration
Application: Municipal water and wastewater treatment
Project Outcomes
Challenges Solved Through Disciplined System Modernization
Municipal treatment facilities require upgrades that minimize operational risk while accommodating long asset lifecycles and future demand. Turn-Key Controls delivered a solution that balanced continuity, modernization, and expandability.
Controlled OS Migration
The transition from iFIX to APACS+ OS was executed in a way that preserved operator familiarity and avoided disruption to ongoing treatment operations.
Future-Ready Control Architecture
The control system was expanded to include a dual-leg SIMATIC S7 automation platform, providing a foundation for redundancy and future process growth.
Operational Continuity During Upgrade
Modernization and expansion activities were sequenced to maintain plant operation throughout the project lifecycle.
Long-Term System Supportability
The resulting architecture supports future upgrades, integration, and maintenance without forcing a full system replacement.
Why It Matters
Modernization Without Disrupting Essential Infrastructure
Water and wastewater facilities operate under continuous public service requirements, making control system upgrades inherently high risk. This project demonstrates Turn-Key Controls’ ability to modernize legacy automation platforms while preserving operational stability and enabling long-term expansion.
