How to Determine the Probable Yield of Wells? | Geography

The following tests may be performed to get an idea of the probable yield of the well: 1. Pumping Test: The water level is depressed to an amount equal to the safe working head for the subsoil. Then the water level is kept constant by making the pumping rate equal to the percolation into the well. The quantity of water [...]

How to Test the Yield of a Well? | Geography

After a well is constructed and developed, it should be tested for its yield and the corresponding drawdown. The equipments required for conducting an yield test are: (i) A test pumping unit consisting of a submersible pump (with 3-phase motor) and a diesel generating set (since power may not be available at the time of test near the well site). [...]
