assessment of system operations, organizational
<br />policies, communications, technical infrastructure
<br />(both hardware and software), computer security, data
<br />integration, support outsourcing agreements, power
<br />reliability and instrumentation associated with the
<br />SCADA system. The project provided a recommended
<br />project and initiatives list to address all identified system
<br />gaps between the current state and intended vision of
<br />the system. A final portfolio was developed with City
<br />input and included budgetary costs for the City to update
<br />and expand its SCADA system to the latest industry
<br />standards, improving support and maintenance with
<br />reliability, security, and expandability.
<br />Los Angles Advanced Filtration Plant UV
<br />Disinfection Facility, Los Angeles Department of
<br />Water and Power, CA: Project Engineer providing
<br />analysis of the ultraviolet (UV) treatment system to
<br />develop a control strategy for disinfection using 14 UV
<br />reactors. The facility had a capacity of 700 million gallons
<br />per day (mgd) making it the second largest UV facility in
<br />the country. System components included three electrical
<br />actuated butterfly valves and flow meter for each reactor,
<br />three redundant system UV transmittance analyzers, and
<br />a common UV return pump station.
<br />Tucson International Airport Area Groundwater
<br />Remediation Project (TARP) Water Treatment Plant
<br />Improvements, City of Tucson, AZ: Project Technical
<br />Lead responsible for programming, configuration, and
<br />start-up of a new advanced oxidation process (AOP) for
<br />treating 8 mgd of groundwater to reduce 1,4=dioxine
<br />concentrations. The site consisted of Rockwell PLCs and
<br />software components. The effort included analyzing the
<br />treatment processes to develop an automation strategy,
<br />and incorporating peer-to-peer communications with
<br />nine existing remote well pumps and existing packed
<br />column aeration (PCA) system used in trichloroethene
<br />(TCE) treatment. The new process included influent
<br />booster pumps, hydrogen peroxide storage and feed,
<br />UV treatment, granular activated carbon (GAC) vessels,
<br />and vessel backwash waste collection.
<br />SCADA Master Plan and Implementation, City
<br />of Tempe. AZ: Project Technical Lead responsible for
<br />analyzing the City's SCADA system including a baseline
<br />assessment of system operations, organizational policies,
<br />network communications, technical infrastructure,
<br />cyber security, data integration, SCADA outsourcing
<br />agreements, and electrical power reliability and
<br />monitoring. Performed a baseline assessment and
<br />identified gaps detrimental to the City's intended SCADA
<br />system vision. Evaluated several alternatives initiatives
<br />to create a final project portfolio which included cost
<br />estimates and schedule. As a separate document to the
<br />master plan, analyzed the City's current SCADA system
<br />architecture, programming and configuration, and future
<br />system vision to develop SCADA Standards. It included
<br />standards pertaining to instrumentation, IT and network
<br />equipment, HMI architecture and graphics design,
<br />data collection and storage, HMI/PLC programming
<br />templates, raw I/O configuration, maintenance protocols,
<br />and other common programming and configuration
<br />tools. The document serves to improve maintenance
<br />and troubleshooting internally for City staff and provide
<br />guidance for external integrators of the SCADA system.
<br />SCADA Master Plan and Implementation, Various
<br />Clients: Project Technical Lead for various SCADA
<br />master planning and implementation projects. SCADA
<br />master planning clients include: the City of Davis,
<br />California; the Town of Marana, Arizona; and the cities
<br />of Baytown and Denton, Texas.
<br />South Tempe Water Treatment Plant Water Quality
<br />Improvements, City of Tempe, AZ: Project Technical
<br />Lead responsible for the programming, configuration,
<br />and start-up of new plant PLCs, HMI software,
<br />integration with vendor PLCs, and deployment of
<br />custom reports using Microsoft SQL Server/Reporting
<br />Services. Worked together with City personnel to analyze
<br />the SCADA system and treatment process to develop an
<br />automation strategy for each system and achieve plant
<br />operational objectives. Collected feedback on HMI
<br />development and trained operators and maintenance
<br />personnel on the new function of the control system. The
<br />project included control system upgrades to the entire 50
<br />mgd facility and added new systems for powder activated
<br />carbon (PAC), carbon dioxide, sodium hydroxide, and
<br />finished water pump station electrical upgrades.
<br />Central Arizona Project Water Treatment Plant,
<br />City of Scottsdale, AZ: Project Engineer evaluating
<br />existing and developing new operations and maintenance
<br />documentation for the addition of a third treatment
<br />train including dissolved air floatation and membrane
<br />filtration systems, increasing the plant's overall
<br />production capacity from 50 mgd to 80 mgd. The project
<br />included modifications to existing raw water pumping,
<br />conveyance, and metering. Chemical storage and feed
<br />modifications were also performed for alum, chlorine
<br />gas, polymer, sodium hydroxide, sodium hypochlorite,
<br />and sodium permanganate. Along with new DAF and
<br />MF additions, the project incorporated new mixing
<br />components, pre-treatment contact basin, finished water
<br />reservoir, and electrical distribution system.
<br />Central Arizona Project Water Treatment Plant
<br />Regulatory Improvements Project, City of
<br />Scottsdale, AZ: Project Engineer responsible for
<br />developing operations and maintenance procedures for
<br />the addition of eleven Granular Activated Carbon (GAC)
<br />adsorption contactors and associated pumping and
<br />recharge systems with a production capacity of 75 mgd.
<br />The goal of the project was to improve finished water
