An infiltration gallery is a subsurface source of water used for a water supply system whose structure is like a horizontal drain that is positioned below the water table so that it collects the groundwater.
An infiltration gallery is a subsurface water supply system that collects groundwater from a horizontal drain situated below the water table. It is designed to resemble a drain and is responsible for sourcing water from subsurface sources.
Infiltration gallery definition: Infiltration gallery is a horizontal drain structure made from open jointed pipe or perforated pipe, or block drain to collect water from subsurface water level. So it laid below the water table to collect groundwater.
An infiltration gallery is a structure including perforated conduits in gravel to expedite transfer of water to or from a soil. Water supply. Infiltration galleries may be used to collect water from the aquifer underlying a river.
Infiltration Galleries: Ground water travels towards lakes, rivers or streams. This water which is travelling can be intercepted by digging a trench or by constructing a tunnel with holes on sides at right angle to the direction of flow of underground water.

Infiltration gallery is a horizontal perforated or porous pipe which opens joints, surrounded by a gravel filter envelope laid in a permeable aquifer with a high water table and a continuous recharge with a perennial flow.
Infiltration galleries (see figure below) typically consist of perforated pipes installed horizontally underground within permeable fill (gravel) material to rapidly infiltrate stormwater runoff and prevent flooding. Infiltration galleries can be used to support groundwater replenishment.
1. Infiltration Galleries. Infiltration galleries are also known as horizontal wells as they are horizontal or nearly horizontal tunnels that are constructed through the water-bearing strata along the banks of the river. The tunnel is often placed at a shallow depth of 3 to 5 meters.
Infiltration galleries are often installed in shallow or fine sediment beds where there is poor permeability or lack of sand depth – in this case, the length proves to be advantageous. They can also be sited in areas where riverbanks are too high to allow manual or motorized suction pumps to operate.
