According to Trabzon Electricity Distribution Local Directorship's statistical data, there are 208.000 utility poles in Trabzon, 180.000 utility poles in Rize, and 121.000 utility poles in Artvin. Every year, 17.000 new utility poles are placed in these three cities. The average lifetime of a treated-wood utility pole is typically 40 to 50 years. However, the average lifetime of a treated-wood utility pole in the Eastern Black Sea Region is only about 10-15 years. In this study, the suggestions for enhancing the service life of treated-wood utility poles in Artvin vicinity were listed by determining the deteriorations and degradations using both visual inspection and nondestructive test methods. The results showed that the most important factors affecting the service life of utility poles were the decay due to fungi, insects, inadequate impregnation, and the deep cracks and splits.
