What is natural groundwater recharge?

What is natural groundwater recharge?

Groundwater is recharged naturally by rain and snow melt and to a smaller extent by surface water (rivers and lakes). Recharge can help move excess salts that accumulate in the root zone to deeper soil layers, or into the groundwater system. Tree roots increase water saturation into groundwater reducing water runoff.

What are the benefits of artificial recharge?


  • No large structures (dams) needed to store large volumes of water.
  • Stored water is relatively well protected from evaporation and pollutants.
  • Schemes can be implemented incrementally, keeping initial capital investment relatively low.

What are recharge ponds?

An infiltration basin (also known as a recharge basin or in some areas, a sump or percolation pond), is a type of device that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay.

What is groundwater discharge and recharge?

Replenishment of infiltrating groundwater is known as recharge. Discharge of groundwater occurs when water emerges from the ground. Confined aquifers are generally recharged where the aquifer materials are exposed at the surface (outcrop).

How can I increase ground water level in my home?

Ground water level can be increased by ground water conservation and control use of water….

  1. Employ rain water harvesting techniques: see for example https://www.watercache.com/education/rainwater-harvesting-101.
  2. Minimize use of water and impose higher water rates for big water consumption.

How groundwater is being recharged?

For example, groundwater can be artificially recharged by redirecting water across the land surface through canals, infiltration basins, or ponds; adding irrigation furrows or sprinkler systems; or simply injecting water directly into the subsurface through injection wells.

How can I increase my groundwater level?
