Nancy Baker, Flow Meter inROV253- Anaheim, CA: Project Manager for apreliminary design <br />PE, ENV S P report (PDR) and design documents for construction of a new flow meter on an <br />existing 36-inch cement mortar lined and coated steel transmission main located <br />(Continued) near ROV (remote operated valve) 253 located in Santa Ana Canyon Road at the <br />intersection of Mohler Drive. The project includes determination of the optimum <br />design to measure the flow by either an insertion type flowmeter located in an new <br />concrete utility vault or installation of a new magnetic type flowmeter in the existing <br />Vault M-68. Both alternative requires instrumentation, power, SCADA and remote <br />monitoring controls and integration with the Water Division SCADA system. <br />Engineering Design Services for Drilling Two New Wells (Wells 60 and 61) <br />- Anaheim, CA: Project Manager to provide hydrogeological evaluation, design, <br />and resident hydrogeology for two new wells. These two wells are part of Anaheim's <br />PFAS Groundwater Treatment Plants (GWTP) project that is constructing centralized <br />and wellhead treatment plants to make up for lost groundwater production due <br />to the presence of PFAS chemicals. The key objectives of this project included <br />review existing studies, reports, logs, and plans and provide recommendations on <br />layouts, materials, and equipment required for the well development. Preparation <br />of construction documents that include drawings and cost estimates, and develop <br />pertinent well construction technical specifications. Assisting in acquiring permits. <br />Providing services during bidding through award and hydrogeological support <br />during construction. The two wells are currently under construction and the project <br />is on track to meet the highly accelerated construction schedule. <br />Miscellaneous Water Vault Rehabilitation, Replacement, and/or <br />Abandonment Project, M-2, M-3, M-8, M-10, M-25, M-26, M-33, M-49, M-55, <br />M-68, and M-94 - Anaheim, CA: Project Manager/Project Engineer for design <br />engineering and engineering services during construction to rehabilitate, replace, <br />and/or abandon 11 water vaults located throughout the City of Anaheim. Project <br />included replacement of butterfly, plug, and gate valves ranging in size from 20 to <br />36 inches. Replacements included replacement of valves within the existing vaults <br />and direct burial of three 36-inch flanged butterfly valves and appurtenances. A <br />preliminary design report/memorandum was prepared to document the results of <br />a conditional assessment for each of the vaults. Preliminary and final construction <br />documents were prepared based on the preliminary design report. <br />Rehabilitation of Wells 41 and 43 - Anaheim, CA: Project Engineer to prepare <br />a technical memorandum and construction bid documents for the rehabilitation <br />of Well 41 and Well 43. These wells are over 30 years old and are currently out of <br />service due to reduced specific capacity as a result of biofilm growth on the well <br />screens. In conjunction with our hydrogeologist (Richard Slade and Associates), well <br />data for the two wells was analyzed (caliper and gyroscopic surveys, driller's logs, <br />video logs, water quality data, etc.) and a technical memorandum prepared with <br />recommendations for rehabilitation, including cleaning and installation of a full <br />casing liner. Bid documents were prepared for Well 43, including construction plans <br />and technical specifications. Well 41 rehabilitation was postponed until a later date <br />until new California standards are established for PFOS and PFOA chemicals found in <br />groundwater. <br />
