Nadarajan Sankaran PE <br />Instrumentation & Controls Designer <br />1 I years of experience - Irvine, California <br />Nadarajan (Sanki) brings 11 years of experience for both design and construction of electrical, instrumentation <br />and control (E, I&C) and supervisory control and data acquisition (SCADA) systems. He has provided effective <br />engineering solutions for water and wastewater treatment plants, oil & gas, and mining sectors using both PLC <br />and DCS platforms in the US and internationally. He has developed smart P&ID's, network architecture <br />diagrams, loop diagrams and technical specifications including control philosophies, instrumentation data sheets <br />and instrument schedules in addition to single line diagrams, control schematics, electrical plans and electrical <br />specifications. Additionally, he has both Allen Bradley PLC and HMI programming, redundant SCADA server <br />and historian data configuration experience. <br />EDUCATION <br />MS, Electrical Engineering, <br />University of Melbourne, Australia <br />BA, Business, University of Melbourne, Australia <br />REGISTRATIONS <br />Professional Engineer#0053254, Colorado <br />PROJECT EXPERIENCE <br />City of Santa Ana PEAS Water Treatment Plant Well <br />40 1 OCWD I Santa Ana, California I I&C Controls <br />Engineer <br />Sanki was the I&C controls engineer for a PEAS <br />treatment system that used ion exchange pressure <br />vessels to remove contaminants. This project also <br />included the design of a pre-treatment cartridge <br />filtration, booster pump, and mechanical modifications <br />to an existing groundwater well pump station. <br />City of Santa Ana PEAS Water Treatment Plant Well <br />38 1 OCWD I Santa Ana, California I I&C Controls <br />Engineer <br />Sanki was the I&C controls engineer for a PFAS <br />treatment system that used ion exchange pressure <br />vessels to remove contaminants. This project also <br />included the design of a pre-treatment cartridge <br />filtration, booster pump, mechanical modifications to <br />an existing groundwater well pump station, and a <br />hypochlorite generation and feed chemical system. <br />32nd Booster Pump Station I Long Beach <br />Water Department I Long Beach, California <br />Lead I&C Engineer <br />Sanki performed preliminary analysis of the existing <br />legacy 9600 baud serial radio network with <br />recommendatons to upgrade to an Ethemet-based <br />900 MHz licensed radio system. Telemetry <br />infrastructure included Microwave Data System <br />(MDS) 900 MHz licensed radio network, Schneider <br />Electric M340 processors, and an AVEVA <br />(WonderWare) InTouch SCADA System. Sanki used <br />peer -to -peer communications to network critical flow <br />and pressure and pumping parameters to remotely <br />monitor and control pump station operation. <br />San Fernando Basin Groundwater Remediation <br />Project I Los Angeles Department of Water & Power 1 <br />Los Angeles, California I Lead I&C Engineer <br />Sanki is the lead I&C engineer on the Progressive <br />Design Build (PDB) team for two treatment facilities <br />within the San Fernando Basins (SFB). The facilities <br />will treat contaminated groundwater from the Tujunga <br />(TJ) and Rinaldi-Toluca (RT) Well Fields. The <br />controlled processes include self-cleaning strainers, <br />UV-AOP, Granular Activated Carbon (GAC), <br />hydrogen peroxide, drain pumping station, liquid <br />ammonium sulfate, and hydrofluorosilicic acid <br />chemical systems. <br />Long Beach Municipal Urban Stormwater <br />Treatment I City of Long Beach I Long Beach, <br />California I Lead I&C Engineer <br />Sanki recovered and reviewed vendor (Purifies) PLC <br />and HMI programs for application according to the <br />contract requirements. He incorporated network <br />re -design changes to reflect the pre -procured vendor <br />package and provided technical recommendations to <br />the City to pursue actions for vendor contract <br />non-conformance. <br />Friant-Kern Canal (FKC) Middle Rach Capacity <br />Correction Project Phase 1—Pump Station <br />Friant Water Authority I Lead I&C Engineer <br />Sanki is leading the I&C effort on the new pump <br />station design across five remote sites that draw <br />water from the FKC via turnout structures. Each site <br />consists of licensed Ethernet -based 900MHz radios <br />and Schneider SCADApack PLCs that communicate <br />back to a central base station. Sanki developed RFP <br />language for the Authority -required <br />contractors/suppliers (including the radio supplier, <br />integrator. PLC supplier) and final contract plans and <br />specifications. Controlled processes include cast -in - <br />place concrete wet well with integrated traveling water <br />screen, and a combination of constant and variable <br />speed pumps. <br />City of Santa Ana On -Call Engineering Design Services for PEAS Treatment Systems RFP NO. 22-133 A-27 <br />
