Effective Techniques to Recharge Groundwater in India
Water is crucial for life to continue. In developing countries like India, where some remote regions still suffer from water scarcity, we should proactively invest in recharging groundwater and increasing water levels.
Current state of water resources
Water scarcity is increasing day by day, even in the countries with sufficient water resources, water scarcity is common. This may be due to the various factors like climate change, increasing population, contamination or poor management of water resources. Water scarcity limits the access to the fresh water for drinking and for practicing basic hygiene at home, in schools and in health-care facilities. When water is limited, sewage systems can fail and can become a cause of contracting diseases like cholera surges.
Groundwater is one of the largest freshwater resources on earth. In many parts on the earth especially where the surface water supplies are less, these water needs can be met by using groundwater. Groundwater depletion is increasing due to the excessive groundwater extraction. As the water table decreases it may result in the depletion f the lakes rivers and streams.
Spreading Basins
It is a process where the artificial basins are flooded with surface water. Highly permeable soils are the best for spreading basins. Water is released from these basins based on the inflow rate, percolation rate, and the capacity of horizontal water movement. Regular maintenance is necessary to prevent algae formation and degradation of water quality.

Injection Wells
Injection wells are installed when bore pumps are already in place which leads to a decrease in groundwater levels due to constant usage. Rainy Filters uses an indigenous and patented V-Wire Injection Well Technology to recharge depleting groundwater. The V-wire screens rely on gravitational force and don’t need any additional energy resources to run. They are durable and last for a long time.
Simply put, running rainwater is diverted through a channel into a slit trap pit. This pit is connected to a storage well with filters. The V-wire screen is placed inside the well over and below the percolator pipe. Each time it rains, the excess water on the ground will be diverted into the injection well to recharge groundwater.
