Design
Although one well may be sufficient to solve groundwater and soil salinity problems in a few hectares, one usually needs a number of wells, because the problems may be widely spread.
The wells may be arranged in a triangular, square or rectangular pattern.
The design of the well field concerns depth, capacity, discharge, and spacing of the wells.
- The discharge is found from a water balance.
- The depth is selected in accordance to aquifer properties. The well filter must be placed in a permeable soil layer.
- The spacing can be calculated with a well spacing equation using discharge, aquifer properties, well depth and optimal depth of the water table.
The determination of the optimum depth of the water table is the realm of drainage research .

“Joe ... you remember I said you wouldn’t be cheated?... Nobody is really. Eventually all things work out. There’s a design in everything.”
