A Step-Drawdown Test is an accelerated pumping test for a single well, designed to estimate the aquifer characteristics and performance of a pumped well under three successively higher pumping rates or steps under controlled flow.
What is the purpose of a step drawdown test?
A step-drawdown test (or step test) is a single-well pumping test designed to investigate the performance of a pumping well under controlled variable discharge conditions.
How do you calculate water well drawdown?
Subtract the measurements you collect as the pump is running from the static water level. The difference is the drawdown. For example, if the static water level is 1 foot below the top of the casing and the water level after one hour is 3 feet below the top of the casing, the drawdown at one hour of pumping is 2 feet.
