Creator(s):
One of the US's oldest surviving examples of the wind-driven Archimedes screw-pump.

With a water table several feet below ground level, New Orleans faced a crisis after every heavy rainfall, not just through flooding but also through disease (yellow fever and malaria) caused by impure water. New Orleans was dependent on mechanical means for lifting water from its canals and sewage systems.

A. Baldwin Wood (1879-1956), a young assistant city engineer, designed and installed a system of large screw pumps (axial flow machines) to syphon water and accelerate drainage. By 1915 the Wood screw pump became the most advanced drainage pump in use. After their successful operation in New Orleans, Wood's pumps were built in the Netherlands, Egypt, China, and India. Wood also redesigned Chicago's drainage system.
