Mr. Watson founded this company in October of 1979. His duties include financial management, applications engineering, consulting with customers and sales. Mr. Watson, is a competent and certified journeyman instrument technician and is the RME and qualifier for the Contractors license A and C-10. He also serves as the primary technical advisor. Mr. Watson's technical responsibilities include customer consulting for new projects, new project applications engineering, custom control panel and PLC system design, design review, and supervision of technical engineering staff for systems developed by Aqua Sierra Controls. For the past 30 years Mr. Watson has been responsible for the fabrication and installation of thousands of control systems throughout California. Some of these projects are discussed on the following pages. Almost all of our projects required that we provide new custom PLC and or motor control panels and SCADA panels for the process that we designed and installed.

Prior to this, Mr. Watson was employed by BIF, a division of General Signal Corporation. BIF was a manufacturer of instrumentation and process treatment equipment used in the public water and wastewater industry. Their products included such items as Venturi tubes and DIP transmitters for flow measurement, electrically and pneumatically actuated butterfly valves and a variety of other process instrumentation.

Mr. Watson's position while at BIF was to provide service as the West Coast Field Service Manager for the Los Angeles and Bay Area service offices. He was also assigned as one of four company technical troubleshooters and assigned the 11 western states and associated foreign countries to solve problems with products or the application of the products. Mr. Watson's duties as a troubleshooter included customer technical assistance on troublesome projects including travel to the site to assess, recommend and or make repairs. During his employment at BIF, Mr. Watson obtained factory management training techniques. Technical training all on all products manufactured by BIF including package treatment systems for water quality treatment, disinfection chemical feed equipment and control, process control instrumentation and SCADA telemetry systems. Mr. Watson, while with the company, worked with Los Angeles County Sanitation to develop the standards required by the district to develop a new area of expertise for BIF for industrial water and process wastewater calibration. These procedures are currently being utilized in our services here at Aqua Sierra.
