A closer look at how Canfield Engineering & Integration solves hard electrical, instrumentation, and controls problems — from first concept through commissioning — across water, mining, and industrial facilities.
Biogas Utilization at a Regional Water Reclamation Facility
A regional water reclamation facility added new biogas cleaning and utilization equipment. The additions had to be protected from lightning, metered for power quality, analyzed for arc-flash safety, and folded into the plant’s existing control network — all without disrupting ongoing treatment.
CEI designed an NFPA 780 lightning protection system, added power-quality metering, and modeled the expanded electrical system to deliver device evaluation, protective-device coordination, and an arc-flash study per IEEE 1584. CEI then programmed the new control panels into the plant’s PLC/SCADA and procured them with a factory acceptance test.
The biogas additions came online with tested controls, current arc-flash safety analysis, and full integration into plant operations.
In-Pit Dewatering at a High-Altitude Molybdenum Mine
Dewatering the main pit at a high-altitude molybdenum mine meant delivering power and controls down the pit wall to a series of skid-mounted pump stations — across steep terrain and thin-air elevation where reliability is unforgiving.
CEI produced the construction-ready electrical, instrumentation, and controls design: an overhead pole line carrying power and aerial fiber from the pit rim to the floor, pole-mounted transformers feeding each pump station, VFD pump controls, service-entrance and distribution equipment, grounding, and instrumentation. A power study covered short-circuit, protective-device coordination, arc-flash, and grounding. CEI carried the work through 30/60/90/100% submittals, competitive bid analysis, construction support, and commissioning.
A fully engineered dewatering system delivered from concept through commissioning — bid competitively and built to plan.
PFAS Remediation Facility for a Municipal Utility
A large PFAS plume in the local aquifer required a municipal utility to build a remediation facility — pumping groundwater through sediment-removal and ion-exchange vessels before discharge — with remote monitoring so operators could manage the site off-site.
CEI provided the electrical, instrumentation, and controls design, construction support, and programming: automated valve actuators, coordinated P&IDs, and a design supporting remote access. CEI programmed the PLC and operator interface, configured an RTU for remote monitoring, performed a factory acceptance test, and supported I&C start-up.
Operators can now treat contaminated groundwater and monitor site conditions remotely, restoring a compromised drinking-water source.
