Reclamation infrastructure provides irrigation water to 25% and 60% of the nation's fruit and vegetable rrops, respectively. This water also reaches 31 million people for municipal, residential, and industrial uses. In addition, Reclamation contributes to 17% of nation's hydropower through 53 owned and operated hydroelectric power plants, including the Grand Coulee Dam in Washington, the Hoover Dam in Nevada, and the Buffalo Bill Dam in Wyoming. It is vital to ensure that this water and power delivery is continued and reliable.
The successful operation of this very large and complex infrastructure requires careful coating maintenance planning. Reclamation's assets include small to extremely large facilities ; hard-to-access areas such as confined spaces, remote locations, and rough and steep terrain ; and atmospheric, immersion, or fluctuating immersion exposure conditions. Each scenario affects the maintenance plan, and creative solutions are often required to arrive at a cost-effective approach.
This article describes the strategies used by Reclamation's facility personnel and coatings specialists to inspect, repair, and recoat coated infrastructure. The authors conclude with basic details one should consider when developing a coatings maintenance strategy.Note de contenu : - HYDROPOWER FACILITIES

Tuyaux d'eauIndex. décimale : 667.9 Revêtements et enduits Résumé : Life-cycle cost analysis is a powerful tool for comparing the economics of corrosion control options. It is extremely beneficial to engage the assistance of a cost estimating or economics professional when establishing an LCC evaluation technique and to ensure proper selection of the discount rate. When used in conjunction with a well-designed corrosion management plan, facilities can improve their bottom line and protect their assets from corrosion. It can also be beneficial for contractors to generally familiarize themselves with this type of process, as it can help them better understand how facility owners plan their projects, and they can prepare bids and work plans accordingly.
