Water Main Replacement El Monte, CA I--�----- i CLIENT CONTACT: City of El Monte 11333 Valley Boulevard, El Monte, CA 91731 Leticia Ortiz, Senior Public Works Engineer (626) 580-2022 YEAR COMPLETED: Ongoing KEY PERSONNEL: Joseph Boyle I Maira Salcedo Michael Swan I Benjamin Halbach Kimberly Alexander I Joseph Barrera Chris Riehle SUBCONSULTANT: GMU Psomas was retained by the City of El Monte to provide PS&E, surveying, environmental and permitting, community outreach, and construction support services for the replacement of approximately 6,900 LF of 4- and 6-inch water mains with 8- and 12-inch mains in two areas of the City's distribution system due to their age and to improve fire flow and reliability. Because this is the first phase of a major water main replacement project, the scope also included updating the City's hydraulic model and running various scenarios to determine if the City should standardize on 6- and 10-inch or 8- and 12-inch pipelines for replacement of their aging, smaller diameter mains. This will eliminate the need to stock various different pipe sizes, fittings, valves and appurtenances. Psomas accomplished the scenario modeling, prepared an economic analysis, compared flow and pressure results, and prepared a technical memorandum documenting the analyses and presenting recommendations. After completion of the final design scheduled for early 2020, Psomas will be combining plans for sewer improvements in one of the two neighborhoods with the water improvement plans into one bid set so it can be constructed as one coordinated project to limit disruption to residents and business owners. After completion of 60% design, an amendment was issued to Psomas to design an additional 1700 LF of pipeline replacement in another area where leaks have been prevalent.
