Faribault Public Works Department
The city of Faribault, MN needed to improve and modernize its Wastewater Collection and Treatment Plant. Following an evaluation of the entire plant, it was determined that the project would include a major upgrade to all electrical components, including PLC’s and SCADA system programming.
Faribault is approximately 50 miles south of Minneapolis, Minnesota. The Public Works Department of the city government is responsible for the wastewater collection and treatment for the city’s 23,000 residents. The plant treats approximately 4 million gallons of biosolids annually.
As a key subcontractor, PRIMEX worked in tandem with the electrical contractor on engineering and commissioning the upgrades to the electrical, instrumentation and SCADA equipment. A thin client architecture was utilized to provide scalability and management. Some of the critical upgrades installed included: seven PLC’s, Motor Control Centers on a DeviceNet bus (New and Retrofits) and 28 separately enclosed VFD controllers.
Critical to this project was the Wonderware System Platform that PRIMEX was able to deploy inside the plant on virtualized server hardware. The city expects 4-5 years out of their servers and virtualization allows them to replace hardware rather than upgrading SCADA software licenses saving them money in the long run.
As part of the complete integration services provided, PRIMEX was tasked with overall system documentation which included a comprehensive description of operation along with application programming and overall system responsibility.
PRIMEX was able to deploy Wonderware System Platform across the entire plant. Redundant communications links were used to ensure all communications operated as desired. This led to PRIMEX being retained as the SCADA Integrator for the City.
