Examples of subsurface infiltration technologies. Water for recharge is applied beneath the land surface but above an unconfined aquifer where <br />conditions preclude surface infiltration techniques. This type of application can be utilized where surface, or near - surface, materials have low permeability or <br />where other land uses are not compatible with surface infiltration facilities. <br />18 <br />
