Kimberly conditions and future conditions including Galaxy's Edge. As a first step, water utility <br />Alexander, PE drawings provided by resort staff were converted into GIS, which includes a database <br />of all system components identified in the utility drawings. Average and peak water <br />(Continued) use was developed based on inflow data through three service connections to the <br />City of Anaheim water system, a water utility fixture inventory by collected by <br />Resort staff utilizing a Psomas developed ESRI application for field collection and <br />ArcGIS online, and discussion with resort staff on non -domestic uses including <br />washdown, irrigation, and makeup water to attractions and equipment. The model <br />was calibrated to hydrant flow tests performed throughout the park and SCADA <br />data at the three water service connections. Priority improvements were identified <br />to provide increased flow capacity to move water between all three connections and <br />improve water pressure within the park. Improvements were also identified related <br />to a proposed project within the park to increase fire flow. Recommendations were <br />made for future work to refine the model through additional data collection and <br />analysis. <br />Arbor Street and Locust Avenue Sewer Improvement (SC-0373) - Long <br />Beach, CA: Project Engineer for preparation of a sewer study for an area with <br />approximately 15,000 LF of sewer mains with much of the system constructed in <br />the 1930s and 1940s. Sewers in the study area present many challenging issues <br />including portions with capacity constraints, sags, a siphon under a storm channel, <br />a crossing under a railroad, and sewers running under backyards and a mobile <br />home park. A hydraulic model was prepared in InfoSewer using the City's sewer <br />GIS and available as-builts. Flow monitoring was conducted, and the model was <br />calibrated to both dry and wet weather flow conditions. The calibrated model was <br />used to develop potential improvements that would upsize, divert, and/or realign <br />facilities to alleviate capacity issues identified for peak dry and wet weather flow. <br />Utility research and sewer manhole surveys were conducted to determine feasible <br />alternatives and recommendations for capital improvements. A preliminary design <br />report documented the entire study with recommended capital improvements. <br />City of Pomona Well 36 Pumping Equipment & Transmission Main - Pomona, <br />CA: Project Engineer for construction management services for a water transmission <br />main pipeline which connects two existing wells (Well Nos. 21 and 24), as well as a <br />new well (Well No. 36) to the City's Anion Exchange Plant (AEP). The pipeline is sized <br />to accommodate a future fourth well (Well No. 38). Psomas designed the pump and <br />wellhead equipment for Well No. 36. <br />2020 Sewer Master Plan Update - , CA: Project Engineer for preparation of Yorba <br />Linda Water District's (YLWD) 2020 Sewer Master Plan. YLWD nearly doubled its <br />sewer service area since the previous master plan, taking over the eastern portion <br />of the sewer system that was previously under the control of the City of Yorba <br />Linda. The InfoSewer model was updated and expanded for the entire service area <br />of approximately 9,000 acres using the District's sewer GIS. The update involves <br />extensive sewer flow monitoring for model calibration and determining sewer <br />loading factors by land use type. Build -out land use projections are being used to <br />analyze ultimate conditions. Adding existing septic systems to the sewer collection <br />system is also being evaluated. Existing and build -out model scenarios will be used <br />to develop a capital improvement program for the District along with a complete <br />documentation of the sewer master plan update. This master plan will update the <br />2010 Sewer Master Plan prepared by Psomas teamed with IDModeling. <br />
