It is often necessary to measure the depth to water in a well. The depth to water influences pump selection and placement. It also determines the energy required to lift water to the surface in the pumping process and thus affects the horsepower requirements of the pumping system. It must also be measured to evaluate the efficiency of irrigation pumping systems to determine the need for pump repair or replacement. When a pump discharges water from a well, the water level in the well drops. This occurs because friction losses prevent instantaneous water flow from the aquifer to the well to replace that which the pump has displaced. This drop in water level in the well during pumping is called drawdown.
