Water seepage harvesting galleries are sub-surface groundwater collection systems (tanks) with perforated pipes, typically shallow in depth, constructed in a sloppy area. These underground water collecting tanks can be built alone in a gully or inside a check dam. These tanks will receive seepage water from the adjacent wet soil. The tanks are connected with external pipes from where water continuously discharges by the force of gravity. The discharged water can be used for both irrigation or drinking purposes. This is a low cost intervention where we can get a pure and continuous supply of water.
