From The New York Times, June 18, 1898; page BR408:

Archimedes of Syracuse, when he was in Egypt, invented a machine for pumping bilge water out of the holds of ships.   . . .  A curious model of such an instrument, probably of the late Ptolemaic period, has been found in Lower Egypt. It consists of a terra-cotta cylinder with a screw inside it, 10 inches long and 4-1/2 inches in diameter.

Archimedes Screw A fresco recovered from the House of the Ephebe in Pompeii showing a man driving an Archimedes screw as a treadmill. Now located in the National Musueum in Naples, Italy. Pompeii was destroyed by a volcanic eruption in AD 79 and this fresco was recovered in the mid-1920s.

From The New York Times, November 6, 1927; page E3:

New and highly interesting discoveries are being made, especially at Pompeii, and almost uninterruptedly. The most recent include a mural painting giving the first authentic representation of how the ancient "cochlea," the machine for raising water supposed to have been invented by Archimedes, worked.   . . .   It is a pity that this most interesting painting also contains obscene subjects which prevent it being shown to the general public.

Archimedes Screw Three large Archimedes screws lift treated wastewater to aeration basins at the Fred Hervey Water Reclamation Plant of El Paso, Texas, USA. Built in 1985, the 10-million gallon/day plant treats wastewater to be injected into the Hueco Bolson Aquifer serving El Paso and Ciudad Juarez, Mexico.

Archimedes' Screw The J.U. Smitgemaal pumping station in Kinderdijk, Holland, used to drain water from the Alblasserwaard polders (lowlands reclaimed from the sea) into the Lek river. Built in 1972, its three diesel-driven Archimedes screws have a capacity of 1.35 million liters per minute. This pumping station does the work of 19 windmills dating from around 1740. These windmills are still standing, earning Kinderdijk the title of the windmill capital of the world.
