Water Main Replacement <br />El Monte, CA <br />.......... <br />I I I I I <br />CLIENT CONTACT: City of EI Monte <br />11333 Valley Boulevard <br />El Monte, CA 91731 <br />Lee Torres, City Engineer 1626.580.2055 <br />YEAR COMPLETED: Ongoing <br />KEY PERSONNEL: Joseph Boyle I Maira Salcedo I Michael <br />Swan I Benjamin Halbach I Kimberly <br />Alexander I Dave Moritz <br />SUBCONSULTANTS: GMU <br />Psomas was retained by the City to provide <br />PS&E, surveying, environmental and permitting, <br />community outreach, and construction support <br />services for the replacement of approximately <br />6,900 LF of 4- and 6-inch water mains with <br />8- and 12-inch mains in two areas of the <br />City's distribution system due to their age and <br />to improve fire flow and reliability. Because <br />this is the first phase of a major water main <br />replacement project, the scope also included <br />updating the City's hydraulic model and running <br />various scenarios to determine if the City should <br />standardize on 6- and 10-inch or 8- and 12-inch <br />pipelines for replacement of their aging, smaller <br />diameter mains. This will eliminate the need to <br />stock various different pipe sizes, fittings, valves <br />and appurtenances. <br />Psomas accomplished the scenario modeling, <br />prepared an economic analysis, compared flow <br />and pressure results, and prepared a technical <br />memorandum documenting the analyses and <br />presenting recommendations. After completion <br />of the final design, Psomas will combine plans <br />for sewer improvements in one of the two <br />neighborhoods with the water improvement plans <br />into one bid set so it can be constructed as one <br />coordinated project to limit disruption to residents <br />and business owners. <br />On -Call Engineering Services <br />El Monte, CA <br />CLIENT CONTACT. City of El Monte <br />11333 Valley Boulevard <br />El Monte, CA 91731 <br />Lee Torres, City Engineer 1626.580.2055 <br />YEAR COMPLETED: Ongoing <br />KEY PERSONNEL: Michael Swan I Kimberly Alexander <br />Beginning in 2015, Psomas was retained by the <br />City to update their hydraulic model from a 2010 <br />Water Master Plan and provide on -call modeling <br />services. This update entailed revising demands <br />and supply source data for wells pumping into <br />the system. Following the model update, Psomas <br />has run scenarios for a couple of proposed <br />development projects testing fire flow and <br />developing capital improvement requirements for <br />these new developments. <br />
