Engineering for the Toughest Environments on Earth

Expert Insight: Chlorine vapors, hydrogen sulfide, and constant moisture make treatment plants “electrical killers.” We don’t just wire for power; we engineer for survival.

Corrosive-Resistant Installations

Standard industrial materials won’t last here. We specialize in:

  • PVC-Coated & Aluminum Conduit: Strategically selected to withstand chemical off-gassing and high humidity.

  • NEMA 4X & Non-Metallic Enclosures: Protecting your sensitive controls from the caustic atmospheres of chlorine and fluorine treatment zones.

Pumping & Aeration Power Systems

Aeration and pumping can account for up to 60% of a plant’s energy use. We optimize:

  • VFD Integration (Variable Frequency Drives): Precision motor control to match flow demands, significantly reducing energy costs.

  • Soft-Starter Deployment: Protecting your pumps from “water hammer” and electrical surges during startup.

NEW: Public Infrastructure & Utility Coordination

Unlike general contractors, SEI understands the complexity of public works and the red tape of utility providers.

Direct Utility Liaison

We manage the “Head-End” of your power. SEI coordinates directly with utility providers to manage:

  • New Service Upgrades & Transformer Installs
  • Meter Approvals & Load-Side Engineering
  • Subdivision & Lift Station Infrastructure

SCADA, Controls & Instrumentation

A treatment plant is only as good as its data. SEI ensures your controls are as reliable as your pumps.

Intelligent Control Systems

  • PLC Programming & I/O Wiring: We integrate the logic that manages chemical dosing, filtration cycles, and sludge removal.

  • SCADA & Remote Monitoring: Secure, real-time data feeds that allow operators to manage the plant from a centralized hub via fiber, ethernet, or wireless connections.

  • Instrumentation Calibration: Expert wiring for flow meters, pH sensors, and turbidity monitors to ensure your compliance reports are always accurate.

Facility Modernization & Phased Upgrades

Many facilities are decades old. We specialize in “Live-Site” modernization.

We provide upgrade services that modernize aging infrastructure without interrupting daily operation. Our staging often includes night work or redundant power handling to keep equipment live while we:

  • Retrofit new VFDs onto legacy Motor Control Centers (MCCs).

  • Replace deteriorated conduit and terminations caused by decades of chemical exposure.
  • Rebalance aging circuits to support modern digital monitoring tools.

The SEI Difference: Why We Lead the Water Sector

  • 43+ Years of Municipal Trust: We understand prevailing wage, public bidding, and capital improvement cycles.

  • Safety & Hazard Systems: From fire alarm integration to Arc Flash labeling and NFPA 70E coordination, we protect your people as well as your power.

  • 24/7 Emergency Response: Storms and equipment failures don’t keep office hours. Our teams are ready for rapid-response repairs when critical systems go offline.

Treatment Plant Electrical FAQ

Do you offer preventative maintenance for treatment plants?

We offer monthly, quarterly, and annual plans that include Infrared Thermographic Scanning to identify failing feeders before they cause a plant-wide shutdown.

Can you help with SCADA terminations and labeling?

Yes. We handle the precise terminations and clear, industrial-grade labeling necessary for instant remote diagnostics. We work across fiber, ethernet, and RS connections to ensure a seamless data backbone.

How do you handle work in hazardous or “wet” locations?

We utilize NEMA-rated enclosures, explosion-proof components, and seal fittings as required by NEC Article 500. We also prioritize “Sanitary Design” to ensure no harbor points for moisture or bacteria.

Don’t Let Outdated Electrical Be the Weak Link in Your Facility
