WebDec 1, 2024 · Specific capacity is the ratio of pumping rate (Q, L 3 /t) to water-level decline (drawdown = s, L; SC = Q/s). Because SC data are commonly collected during well drilling and recorded on permits or well-completion reports, these data can be cost-effectively obtained by query of well-permitting databases.

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)
