As a key source of drinking water and strategic resource in my country, groundwater plays an important role in promoting social progress and promoting the construction of ecological civilization. Groundwater over-exploitation will lead to a series of problems such as groundwater resource depletion, frequent environmental geological disasters, and ecosystem degradation, which will cause serious harm to the sustainable development of the economy and society, the health of the people, and the ecological environment.

At present, the measures taken by my country to deal with the problem of groundwater over-exploitation mainly include two aspects: one is to implement strict administrative management and demarcate groundwater prohibition and restricted areas; the other is to carry out artificial groundwater recharge according to local conditions, and increase the storage and availability of groundwater resources through engineering facilities.

What is artificial groundwater recharge

Artificial groundwater recharge is the reverse process of groundwater exploitation. It is a process of replenishing surface water, rainwater or other water sources into the aquifer in a planned manner through river channel reconstruction, infiltration pools, injection wells and other facilities.
Artificial groundwater recharge is a multi-effect water resource management method that can effectively increase groundwater storage, balance the spatial and temporal distribution of water resources, and improve groundwater quality. It is an effective way to achieve groundwater over-exploitation control and surplus water storage.

It can be said that compared with administrative measures such as banning and limiting extraction to suppress or divert groundwater demand, artificial groundwater recharge is a more active, proactive and flexible measure for groundwater resource storage.
