Istanbul has become a center of attraction for three civilizations for 3000 years. As it is famous ancient city of the world and it has growing population, the importance of Trenchless Methods is obvious. There are many historical places where excavation is not possible in Istanbul. In this case, Trenchless Technologies are major alternative and offer many benefits for protecting historical infrastructures and reducing social cost. Currently, renewal and rehabilitation are in application in underground infrastructure such as water systems, gas pipeline and sewer systems. Especially, Cured-in-Place Pipe (CIPP), Fold & Form (F&F), Pipe Bursting and Horizontal Directional Drilling (HDD) methods are widely used for rehabilitation, renewal and new installation of pipelines in Istanbul. In this paper, some trenchless case studies were given, a projection of future was made and the potential of Trenchless Technologies is discussed for Istanbul
