Innovative approaches . . trs � ireese ..w Nichols practical results Timothy E. Campbell, P.E. Electrical /SCADA Years Experience: 12 Registrations: Professional Engineer, Texa: Education: B.S., Electrical Engineering, :sZJ8 1996 ( #81011) Texas A &M University, 1990 Mr. Campbell is experienced in electrical design; project management, coordination of mechanical and electrical disciplines, and vulnerability assessments and emergency operations planning. He has a background in design of electrical and instrumentation for water treatment plants, wastewater treatment plants, and water distribution. He is also skilled in the electrical design of commercial and industrial facilities. Project Experience: Water System Vulnerability Assessments - Brown County WID #1 and the Cities of Abilene, Beaumont, Carrollton, Denton, Corpus Christi, Garland, Irving, Midlothian, Plano, North Richland Hills, San Angelo and Temple, Texas. Reviewed Water Utility Vulnerability Assessments related to power instrumentation and SCADA. Provided not only recommendations for physical improvements, but also operational and procedure changes. Wastewater Treatment Plant - City of Son Angelo, Texas - Design of plant improvements including new headworks, odor control, digesters, sludge handling, gravity belt thickener. The anaerobic digester gas was collected and used to feed the boiler. Wastewater Treatment Plant - City of Beaumont, Texas - Provided the electrical design for the complete replacement of the electrical system for the plant. The existing system was outdated and several portions were not operable due to the extreme corrosion. A new looped primary feed system was installed that fed motor control centers inside air- conditioned enclosures to protect them from the hydrogen sulfide. The motor control centers and various electrical distribution equipment are housed in temperature controlled, prefabricated, 304 stainless steel buildings to protect the equipment from the corrosive environment. Water Treatment Plant - City of Midland, Texas - Designed chemical feed improvements, including chlorine storage and feed system. The $1.2 million improvements included both chlorine and ammonia scrubber systems for the feed and storage facilities. Nitrate Treatment and Other Water System Improvements - City of Vernon, Texas - Provided electrical and instrumentation design for the installation of the Ion Exchange Treatment Plant, elevated storage tank, new well sites and chlorine injection. This project included providing SCADA for the City, containing installation of radio equipment for 34 well sites, and 12 sanitary sewer lift stations. Water Treatment Plant - City of Beaumont, Texas - Designed plant expansion including new filters, pulsators, and chemical feed. Plant capacity was increased to 14 MGD.
