What is Ground water banking and How does it store and save water?
Groundwater banking is the technique of redirecting floods or other surface water into an aquifer where it can be stored for later use.
In a strange twist of fate, the space created by emptying some aquifers allowed for the widespread usage of banking activities today.
The bank is an aquifer that is utilized as an underground storage tank, and water recharge creates an increase in the amount of water stored in the aquifer, causing water levels to rise. There would be a drop in water levels if there was a withdrawal. The volume of water is also affected by a number of other variables, such as groundwater pumping by other users, leakage, and natural recharge.Water recharge by land application or injection increases the amount of water, and part of the water will be utilised in the future.
It may be calculated as inputs minus outputs equalling the change in water storage.
Groundwater banking techniques
Groundwater banking may be done in two ways: in-lieu and direct recharge.
1: In-lieu recharge is a method of storing water that uses surface water "in lieu" of pumping groundwater, storing an equal quantity in the groundwater basin. In-lieu recharging is the use of renewable surface water to irrigate farms instead of traditional groundwater. This contributes to increased groundwater conservation since the water remains in the aquifer to be used later.
2: Direct recharge is a method of storing water by allowing it to seep directly into a groundwater basin. Direct recharge floods a region, allowing water to seep through the earth and reach the aquifers. When there is a higher demand, the water is pumped out using recovery wells.
The Benefits and Drawbacks of Groundwater Banking
Proponents of groundwater banking argue that the state should take use of the vast natural subterranean storage capacity available in aquifers. Some water authorities have already done so. There are worries, however, that increased underground storage might expose water in certain places to legacy toxins already present in aquifers.
Groundwater banking are concerned about the possibility of mismanagement or harm to surrounding surface water or groundwater-dependent ecosystems, as well as the possibility of privatizing a public resource.
Adequate data collection, monitoring, and modelling are required for successful groundwater banking. These elements are critical for gauging an aquifer, evaluating its groundwater banking capacity, silting and confirming how the water travels once it's in the ground, and analysing the project's costs and benefits.
The water bank serves a dual role: as a water supply and a wildlife habitat, preserving and protecting vulnerable and endangered native plant and animal species.
Regulatory Structure
To execute the withdrawal rates and ensure that other players do not drain too much stored water, the banking systems require regulatory authority over the basin.
Water management tactics are used to limit the amount of wastewater produced and, if necessary, to treat it before releasing it as well as conservation of water resources.
