Description:
This historic diagram, which has been digitally enhanced and colorized, depicted the surface construction of 'dug'-, 'drilled'-, and 'driven'-type wells that had been equipped with pumps of the 'deep well'-type, and submerged internalized cylinders. The cross-sectional renderings identified the components, and placed them into the approximate relationship to one another, in their optimal positions, in order to achieve maximum performance efficiency.
