In recent years, the widespread exploitation of groundwater in agricultural production in the Mekong Delta has caused a serious decline in water resources. Meanwhile, the El - Nino phenomenon, prolonged drought, and the blocking of hydroelectric dams by countries in the Mekong River basin have depleted freshwater resources in the system of rivers, canals and reservoirs in Vietnam. downstream countries. This leads to the risk of lack of fresh water for production and daily life, the depletion of groundwater resources and reduced quality due to salinization.

In the world, the application of groundwater collection and replenishment methods was implemented first in 1891 in the Soviet Union, then in the US, Europe, and Latin America... Therefore, the group proposed an initiative to restore the water supply. service for artificial replenishment of underground water in the Mekong Delta, on the basis of understanding the hydrogeology of this area, combined with propaganda solutions to raise awareness and responsibility of each individual. in social. With the desire to build a conscious community when treating polluted water, solutions to adapt to saltwater intrusion, raising groundwater levels in living areas.
