Gray & Osborne, Inc., Consulting Engineers <br />PROJECT M-1: RESERVOIR COVER REPLACEMENT/REHABILITATION <br />Schedule: 2018 <br />Estimated Cost: $81,300 <br />Although still in good condition, the existing reservoir cover will likely require <br />replacement or rehabilitation within the 6 -year planning period. <br />PROJECT M-2: BRIDGE MAINTENANCE AND PAINTING <br />Schedule: Beyond 2018 <br />Estimated Cost: $384,000 <br />With the transmission main being replaced on the bridge, the bridge requires on-going <br />maintenance to ensure reliability and reduce the risk of bridge failure. Minor structural <br />repairs will be completed, including replacing approximately 100 corroded rivets with <br />high strength bolts. Additionally, spot paint repairs will be made to prevent further <br />corrosion. Due to the sensitive nature of the Cie Elum River, the bridge will be fully <br />contained during painting. <br />PROJECT O&M -1: SERVICE METER REPLACEMENT <br />Schedule: Annually through 2018 <br />Estimated Cost: $10,000 annually <br />As part of their Water Use Efficiency Program, the City is committed to accurately <br />metering and billing for water used by customers. Service meters normally have a life of <br />approximately 10 to 20 years. The existing service meters were mostly installed during <br />the 1992 project. Consequently, they are near the end of their expected life. The amount <br />budgeted should allow for the City to replace approximately 120 meters annually. <br />PROJECT O&M -2: FINISHED WATER METER <br />Schedule: 2013 <br />Estimated Cost: $7,100 <br />The City has experienced decreased demand during the winter, resulting in flows outside <br />of the ideal flow range for the 12 -inch finished water meter. The City plans to replace the <br />existing meter with a smaller mag -meter to increase meter accuracy. <br />PROJECT O&M -3: BACK-UP POWER AT RESERVOIR <br />Schedule: 2014 <br />Estimated Cost: $15,700 <br />The City plans to install back-up power at the reservoir to ensure continuous operation of <br />the motorized butterfly valve and telemetry at the site. Uninterruptible batter back-up <br />supply would have the ability to power the necessary equipment for up to 8 hours in the <br />event of a power outage. <br />June 20,14 Water System Plan <br />
