This inverted siphon was used to draw the fire's hot fumes up the front and down the back of the Franklin stove's hollow baffle, in order to extract as much heat as possible from the fumes. The earliest known example of such an inverted siphon was the 1618 fireplace of Franz Kessler. [9] The fire burned in a ceramic box.
The Romans used inverted siphons of lead pipes to cross valleys that were too big to construct an aqueduct. [41] [42] [43] Inverted siphons are commonly called traps for their function in preventing sewer gases from coming back out of sewers [44] and sometimes making dense objects like rings and electronic components retrievable after falling ...
Inverted siphoning occurs below the line "A". Examples of traps In plumbing , a trap is a U-shaped portion of pipe designed to trap liquid or gas to prevent unwanted flow; most notably sewer gases from entering buildings while allowing waste materials to pass through.
Four inverted siphon tunnels cross the particularly deep and wide river valleys of the Durèze, the Garon, [4] the Yzeron and the Trion on pipe bridges raised on high arches. In these, water filled a sunken tank tower (castellum [5]) on the brim of a slope. The tank effected a transition between open channel flow and a lead pipeline.
In 1863, work began on the construction of a modern sewerage system for the rapidly growing city of Frankfurt am Main, based on design work by William Lindley. 20 years after the system's completion, the death rate from typhoid had fallen from 80 to 10 per 100,000 inhabitants.

Siphon tubes are a basic implement used in irrigation to transfer water over a barrier (such as the bank of a raised irrigation canal), using the siphon principle. At the simplest they consist of a pipe with no working parts. To work they rely on the water level in the canal being at a higher level than the water level in the field being irrigated.
A lift station is a sewer sump that lifts accumulated sewage to a higher elevation. They may also be used to prime an inverted siphon used to cross underneath rivers or other obstructions. The pump may discharge to another gravity sewer or directly to a treatment plant. [6]
