Vadose zone infiltration wells (VZWs), also called dry wells or recharge shafts, is an important technique to implement MAR in semiarid and arid regions where groundwater table is deep (e.g., 100–300 m or more) or sufficiently permeable soils and/or sufficiently large land areas for surface infiltration systems are not available (Bouwer, 2002).
