The pump station receives <br />water from several sources including three wells, and one connection with the Metropolitan Water <br />District (MWD). In addition, a six million gallon reservoir resides at this site providing emergency <br />and peak demand water supply. This facility is the main component to distribute water to the <br />central and downtown areas, and is therefore considered critical to the City's water distribution <br />system. <br />On September 16, 2014, the Public Works Agency entered into an agreement with Psomas, Inc. <br />for engineering design services to renovate and modernize the Walnut Pump Station. The <br />design was completed by Psomas, Inc. as scheduled. <br />On September 20, 2016, the project construction phase was awarded to Arnaz Engineering <br />Contractors. During the initial part of the construction phase, several related mechanical and <br />electrical equipment appurtenances were found in a state of decay and must be replaced. This <br />could only have been discovered when the pump station was taken off line and disassembled. <br />Equipment includes booster pumps, well head piping systems, electrical motors, components, <br />25G -1 <br />
