Water Harvesting – Guidelines to Good Practice (Water Harvesting)

A recharge well consists of a long inner tube surrounded by an outer tube, the circumference of which ranges between 1 and 2 m. The area between the tubes is filled with river bed gravel which acts as a sediment filter. Water enters the well through rectangular-shaped openings ( 20 cm long and few mm in width) located in the outer tube, and it flows in the inner hole passing through the gravel and the rectangular shaped openings of the dill hole.  The above-ground height is around 2 to 3 m and the depth is  40 m.   The filtered water can directly flow into the aquifer at a rate exceeding what would occur naturally through the soil and the underlying strata.
