Project Experience
Seneca Water Treatment Plant
​Raw Pump Station Design
Seneca, SC
UTEC developed specifications and the electrical design of a 480V Motor Control Lineup and associated starters and variable frequency drivers.

Seneca Water Treatment Plant
Primary Electric System Improvements
Seneca, SC
UTEC developed specifications and the electrical design associated with the Seneca WTP Primary Electric System Improvements project.  This work included design of a 4.16 kV Loop Feed System that provided a redundant primary source to each of the WTP’s five major facilities. 

Other work included facility electrical design, PLC specifications, process instrumentation design, and SCADA system design associated with the WTP’s new Administration/Laboratory Facility and new Sludge Handling facility.

Town of Waynesville, NC
Waste Water Treatment Plant Assessment and Evaluation
Complete assessment and evaluation of the condition and operating efficiency of the town’s waste water treatment plant, including the electrical system. 

Harnett County Public Utilities Department
Energy Cost Reduction Study
UTEC performed a study for the Harnett County Public Utilities Department to review optional retail electric rates offered by Progress Energy (now Duke Energy) to minimize costs.  This study included review of operations to reduce electric costs.
