When water levels drop below the levels of the pump intakes, then wells will begin to pump air - they will "go dry." Pumping a well lowers the water level around the well to form a cone of depression in the water

Guidelines for the Design of Buried Steel Pipe July 2001

In 1999, ALA requested a group of civil and mechanical engineers, listed in the Acknowledgements, to prepare a guide for the design of buried steel pipe. The group prepared the guidelines presented in this report, with an emphasis on the fundamental hw = distance between the top of the pipe and the ground water I.
