Abstract
This paper is a review about infiltration wells as one of technology based approach in water and land conservation on watershed management. Infiltration wells is a building construction for enhanced infiltration in urban area which provided artificial water by injecting rainwater into the soil. Increasing of infiltration volume will reduce runoff volume which is part of the rainfall that flows above the ground to the rivers, lakes and oceans. In the integrated watershed management that runoff is one indicator for a good watershed management called coefficient of runoff (C). The coefficient C is the ratio between the volume of runoff to rain intensity. The increasing of urban area, it will enhanced the value of coefficient C close to the value of 1 where most of the rain intensity becomes runoff. It is expected that with the infiltration wells in urban area then the volume of rainfall will be infiltrated more so that the volume of runoff will reduced.
