City of St. Lucie, Florida: Designing a Better Water and Wastewater Control System

, ,


St. Lucie West Services District (SLWSD) is a water/wastewater and irrigation water services provider located within the incorporated limits of the City of Port St. Lucie, Florida. SLWSD was created in 1989 to support a planned development community under development by Core Communities of Montreal, Canada. SLWSD provides service to a total of 20,000 residents in the City of Port St. Lucie, Florida. The district uses their SCADA system to manage, maintain and monitor five different processes: a reverse‐osmosis plant, a waste water treatment plant, a lift‐station collection system, a storm water control system and a reuse distribution system. Over the years, St. Lucie West has expanded and upgraded many of its processes.

As the utility grew, so did the needs and requirements of the SCADA system.

Project Highlights

The district was interested in finding another SCADA solution, hoping to remove some of the limitation of their existing system and to provide flexibility for the future. We worked closely with SLWSD management to evaluate their needs, their existing SCADA system and other potential replacement SCADA systems. After a thorough review process SLWSD chose Inductive Automation’s Ignition system. Complete Systems Automation and Integration Services worked diligently to recreate the entire system in Ignition. The new system was brought online one plant at a time.


The staff at St. Lucie West is very happy with the system and all indications are that the system runs flawlessly.
