WebSpecific capacity data are readily available at many locations in a basin. For little effort (compared to conducting an aquifer test) we can obtain an approximation of … Specific capacity is a quantity that which a water well can produce per unit of drawdown. It is normally obtained from a step drawdown test. Specific capacity is expressed as: where is the specific capacity ([L T ]; m²/day or USgal/day/ft) is the pumping rate ([L T ]; m³/day or USgal/day), and is the drawdown ([L]; m or ft)

WebSpecific capacity is defined as the rate of discharge of a production well per unit drawdown and is calculated by dividing the pumping rate by the change in head for each step (Fetter, 2001).
