Modernizing utility operations with an open architecture SCADA system
After nearly 20 years of reliable service, Lexington-Fayette Urban County Government’s (LFUCG) SCADA system had become obsolete, with aging hardware, outdated HMI software and limited replacement options. Following a needs assessment, LFUCG chose to upgrade electrical and SCADA systems at two wastewater treatment plants and replace all 80 remote terminal units (RTUs) across its pump station network. Our team led multi-agency stakeholder workshops to define the SCADA architecture, developed new processes and control documentation and evaluated telemetry and communications system-supporting a full system redesign while keeping all facilities operational during the transition.
Two wastewater treatment plants upgraded
SCADA systems were upgraded at two wastewater treatment plants, including new control functionality at West Hickman.
Open architecture SCADA system
The project implemented a Rockwell RTU-based SCADA system using open architecture hardware and software.
Improved reliability and automation
The upgrades improved reliability, automation and staff productivity while preparing the utility for future growth and storm response.
The upgraded SCADA system modernized equipment at both wastewater treatment plants, added active control functionality at West Hickman and replaced proprietary RTUs with a Rockwell RTU-based system and upgraded radio communications. The open-architecture design standardized systems across the organization, enabled advanced automation at plants and pump stations, improved reliability and staff productivity and positioned LUFCG for future growth and long-term operations.
