ALERT System Engineering


WET has experience in the design, planning, installation, operation, and maintenance of automated environmental monitoring networks. We install and maintain both Automated Local Evaluation in Real Time (ALERT) and Supervisory Control and Data Acquisition (SCADA) telemetry-based monitoring systems. Our hands-on field experience combined with our engineering and hydraulic expertise allows us to design and install systems to meet specific monitoring needs. WET professionals have more than 60 years of combined installation and operational experience that has been achieved by working on gaging networks throughout the continental United States, Alaska, Canada and Central and South America.

WET provides complete project management from the design of the monitoring network through radio licensing, installation, and long-term maintenance.

WET utilizes programmable dataloggers to measure water levels in streams, lakes, evaporation pans, and wells. We deploy sensors that monitor temperature, precipitation, wind, relative humidity, barometric pressure, conductivity, dissolved oxygen, pH, turbidity, and other environmental parameters. These remotely sensed parameters are communicated using either ALERT or SCADA telemetry protocols. Data from remote stations are received at a central site for processing, analysis, and archival.

WET also has experience installing automated sampling equipment for hydrologic and water quality monitoring for regulatory permitting.
