[free report] Recharge pits

The level of groundwater is decreasing in major towns. Ancient towns like Kathmandu where citizens were dependent on ground water for their needs are experiencing drying of these water sources. The major cause for this depletion of ground water is disruption of water recharge cycle from rainfall due to concrete structure in land. To the solution the concept of recharge pits is evolving.

The measure is called artificial groundwater recharge pits. These are well like structures covered by stones and gravels which make a porous soil for rainwater to accumulate as ground water. The pit can be constructed with any dimension but ideal size is considered to be 1-2-meter-wide and 2-3 meter deep. The site is excavated till weathered rock or fracture is reached. The pit once dug is filled with coarse gravel and sand. Larger stones and put towards bottom and smaller towards top. The leaves, layer of soil can also be used for covering the pit. Care should be taken to remove sediments accumulated by running water. Debris should be prevented and cleaned time to time to ensure water is being absorbed.
