Systems Integrated (SI) is the company that city and county agencies look to for providing complete turnkey solutions for their Intelligent Transportation System (ITS) communication network. A successful ITS implementation relies on a seamless communication network connecting traffic intersections along a corridor to enable the intelligence function.


SI designs, constructs, configures, installs and supports Supervisory Control and Data Acquisition (SCADA) systems for water and wastewater utilities. Our electrical, mechanical, application and quality assurance engineers develop the most effective solution for our customers, applying an agnostic approach for providing hardware and software solutions. From field instrumentation up to the control room, a complete system can be provided.


Systems Integrated provides complete automation services for utilities with needs in their substation, distribution and hydroelectric facilities. Our services include engineering, installation, test and support for hardware, communication links and software neces-sary to connect the facility to your control room.


The SI Government Services Division (GSD) is uniquely positioned to provide support to a vast array of Anti-Submarine Warfare (ASW) and ocean science programs, leveraging the engineering knowledge of SI and the subject matter expertise of a number of key individuals who have worked in the epicenter of ASW during the Cold War – OPNAV, SPAWAR, ONR, and the Navy labs.


  • "We chose Systems Integrated based upon their worldwide experience and detailed design expertise in similar projects with dozens of large scale hydroelectric plants around the globe. But what sets them apart from other firms is that they really care how the project gets completed and that it works the way that LADWP wants it to work. They were always available whenever we had a question and we’re able to answer all our questions live."

    LADWP Castaic Project Manager Emeritus
  • “Systems Integrated just completed a major upgrade of our SCADA system for control and monitoring of the potable water system. The system consists of a main Operations Control Center, a backup North Operations Center and 120 PLC control panels connected via wired wide area telecommunications network.

    Systems Integrated was responsible for the system design, engineering, PLC panel manufacturing, installation and start-up for the system. Once we completed the SCADA system hardware upgrade we installed the onSITE© version 8.0 release and it has performed flawlessly.”
