Water and wastewater facilities are a vital need for the survival and growth of any community.  These facilities ensure the treatment and delivery of potable water as well as the collection and treatment of wastewater.  While recognizing that this is a continuous process industry, we design electrical facilities to ensure power reliability, operate and control large motors, automate process flow systems, and establish sophisticated SCADA monitoring systems. 

Electrical systems for water and wastewater facilities require a design configuration that is suitable for fulfilling the needs of a continuous process industry. This often includes the reliable distribution of the incoming medium voltage power supply to sub-distribution electrical systems that directly feed the process loads. Process loads can involve motors ranging from fractional horsepower ratings to 5,000 HP which require specialized motor control centers, variable frequency drives, reduced voltage soft starters, and harmonic correction units. As most facilities are either fully automated or automated with remote-manual override, a reliable PLC and SCADA system design also becomes necessary to form a reliable instrumentation and control (I&C) system. We understand that no two facilities are the same and focus on providing design, integration, startup, commissioning, and testing services to ensure that a given facility can achieve operational excellence.

  • Electrical Substations

  • Backup Generation (Standalone or Paralleled Systems)

  • Motor Control Centers
