A subsurface dam is a system which
stores additional natural groundwater by means of a “cut-off wall” also called a dam body. It is set up across a groundwater channel which can include aquifers, underground river systems, or a subsurface valley.

  Increases groundwater volume without disturbing the surface environment
  Less evaporation than surface dams
  High water quality
  Stable &secure: ground acts as a reinforcement
  Short construction period

Stores fresh water, which can be used for:

  Sustaining growing populations
  Supporting new industries
  Facilitating the needs of increased agricultural production
  Creates jobs

  Hard bottom layer with low permeability.
The sides and the bed of the reservoir must
consist of basement rock with low permeability. If there are large water bypaths, the dam cannot store water effectively.
  Presence of a porous layer / aquifer for water storage
  Presence of shallow groundwaters with high fluidity to keep water from stagnating
