TSI has the experience and resources to meet your automation and control system needs.


Technical Systems Inc. has been a leader in the application of control systems technology to our municipal clients in Water and Wastewater treatment. Projects range from fabrication of a simple duplex water booster station control panel to the final design, fabrication, programming and start-up, of the 400 MGD Seattle/King County West Point Secondary Treatment Plant. TSI has provided water treatment plant controls, upgrades, monitoring systems, booster station, well and reservoir control and Telemetry panels as well as analytical and measurement devices.

  • Water/Waste Water Treatment Facilities
  • Lift and Booster Pump Station Controls
  • Land Fill-Leachate Controls


Technical Systems Inc. has been involved in an wide variety of industrial control system projects since 1970. During this time our staff of registered professional engineers has developed a working understanding of the processes used in applications ranging from Aerospace and materials handling to Pulp/Paper and Machine Control. As a result of this diverse experience, TSI has the crucial knowledge in process control to implement your system quickly and effectively.

Wireless SCADA/Telementry

With an installed base of well over 3,000 remote sites, Technical Systems Inc. is the Northwest’s leader in the design and supply of telemetry/SCADA for the water and wastewater market place. TSI has supplied simple two site well/reservoir systems to complex systems involving networked computers and multiple water and sewer sites. Whether the data path is over telephone, VHF, UHF, spread spectrum radio, microwave or via a hybrid radio/landline mix, TSI has provided every conceivable type telemetry system.

Fish Hatchery

Over the past 10 years, TSI has designed and integrated numerous control and monitoring systems on Federal, State, Local and tribal hatcheries. In many of the fish hatchery control projects, TSI has provided complete control system upgrades and remote alarm system implementation. From simple monitoring systems on fish raceways, to advanced telemetry and control systems on large fish acclimation facilities, TSI can design, program, install, and commission hatchery electronic instrumentation and control systems.


TSI has implemented a variety of transportation related projects, from PLC based bridge controls for boat passage to vehicular tunnel security. In addition TSI has integrated DC power system monitoring for the bus transportation system. Many rivers and waterways throughout the Pacific Northwest have bridges utilizing TSI control systems.

Using PLC’s and operator interfaces, these bridges allow boat traffic past low level bridges. Bus tunnels in Seattle have automated security systems with CCTV to automatically shut off the tunnel to traffic in case of a security situation. To monitor the electric bus power grid, TSI engineers installed and commissioned a telemetry and monitoring system at many DC substations. TSI is ready and prepared to facilitate any custom transportation project.
