Specific capacity of a well

WebSpecific capacity is a complicated ratio that defines a wells performance at different yields/pumping rates. In order to determine specific capacity, you’ll need to measure Static Water Level, which is the highest point in the well that water reaches without being pumped. You’ll then need to measure drawdown in the well at a specific flow ... WebJul 10, 2014 · We have about 1.5 gallons of water per foot of depth of a well when we're using a standard residential 6" well casing. Below we show how the volume of a well casing is calculated. If your well casing or dug well or other round well is larger than 6-inches in diameter just adjust the radius or r-figure to equal 1/2 of your well's diameter in inches.
