Water WellWe have boreholes that is required to supply water to a community. There are two wells almost 150 m apart. One well is performing really well while the other well has performed really bad. For instance the drawdown test for one well stabilizes at 58 m while the water level at the start of pumping is 50 m and the discharge rate is 32 l/s average. Now, the second well drawdown test shows that the water doesn't stabilizes and goes down to almost 176 m from 57 m at the start while the discharge rate is only 11 l/s. Can anyone please tell me is the second well sustainable if yes what is the sustainable or safe yield from this well?
