Contracts Renewal for Frequency Drives and Motor Control Center Upgrades <br />April 15, 2014 <br />Page 2 <br />Centers (MCCs) with programmable logic controllers. These devices monitor and control the <br />pumps and motors that produce the City's potable water. Additionally, the equipment reduces <br />the amount of electricity consumed to power the pumps and motors. Updating aging pumps and <br />well controllers helps to operate the water system more efficiently and allows staff to improve <br />control of the pressure and flow of water throughout the City. <br />The Water Resources Division staff has identified both the East and Crooke Pumping Stations as <br />requiring new MCCs and VFDs. Both pumping stations were completed in 1970 and require a <br />number of upgrades, including electrical panel replacements to modernize stations. Additionally, <br />both stations are connected to reservoirs and consequently require additional components to <br />complete the upgrades. Given the number of upgrades, the cost to modernize these two pump <br />stations is significantly higher than previously upgraded water wells. <br />Replacing the MCCs and VFDs will allow the water production operators to control the pumps <br />and motors more effectively, and assist in accurately responding to daily water demand <br />fluctuations. In addition to the purchase of upgraded equipment, the vendors provide specialized <br />electrical services which are periodically required at City water wells and water pumping stations. <br />FISCAL IMPACT <br />Funds are available in the Water Utility Water Production & Supply account (no. 06017640- <br />62300). <br />""William- P.E. <br />Interim Executive Director <br />Public Works Agency <br />BI /sp <br />APPROVED AS TO FUNDS AND ACCOUNTS: <br />Francisco Gutierrez' y <br />Executive Director <br />Finance and Management Services Agency <br />228 -2 <br />
