i <br />1 <br />City Council <br />W ITEM NO. <br />Agenda Report <br />BATE: December 19. 2018 t <br />ftr, Y <br />FROM: Stephanie DeWolfe, City Manages <br />PREPARED Y: Dan Ojeda, P.E., Interim Public Works Director ", <br />Anteneh Tesfaye, Water Operations Manager <br />SUBJECT: Ratify Emergency Purchase of a Motor for Wilson Well No. 3 <br />Recommendation <br />It is recommended that the City Council ratify the emergency purchase and installation of a new <br />motor for Wilson Well No. 3. <br />Commission Review and Recommendation <br />This matter was not reviewed by a Commission. <br />Discussion/Analysis <br />On November 15, 2018, the motor for well No, 3 failed. The City immediately increased <br />purchase of Metropolitan Water District of Southern California (MWD) water to cover the <br />production loss without interrupting resident service. Because the installation can only be <br />completed on December 18, 2018, prior to the contractor closing for the holidays, the City <br />Manager has authorized the emergency purchase of a new motor ($33,796). The work will be <br />done by General Pump Company, which the City has maintained a contract with for the past five <br />years to perform this type of work. If the City continued to purchase water through Mid -January, <br />the cost to continue purchasing MWD water would not be in the best interest of the City <br />($133,000). Postponing the purchase of the new motor until January would also risk stalling the <br />wellhead treatment installation and permitting—as both wells must be operational to complete <br />this process. <br />Background <br />Well No. 3 is located at the Wilson Reservoir, which is in the City of San Gabriel and is one of <br />the City's four water production wells. Drilled in 1948, well No. 3 is the highest production well <br />that accounts for 64% of the ground water supply from Wilson Reservoir site. In addition, it is <br />utilized frequently for optimal operation because of the better water quality over Wilson Well <br />No. 4. The replacement of the well motor is critical to ensure continued operation of the <br />temporary well head treatment system and to reduce the amount of purchase water required to <br />supplement the City's water demand. In addition, operation of both Wilson Well No. 3 and <br />Wilson Well No. 4 is required for the testing and permitting of the permanent well head <br />
