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 ...
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.

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.

This water system could deliver around 6 million gallons of water per day (GPD). The initial stage of the project included the construction of a diversion dam on Hobart Creek, a wooden flume from the dam to an inlet tank which was 4.6 miles long, and the 7 miles of twelve-inch riveted wrought iron pipeline, the inverted siphon. Another flume ...
Roman engineers used inverted siphons to move water across a valley if they judged it impractical to build a raised aqueduct. The Roman legions were largely responsible for building the aqueducts. Maintenance was often done by slaves. [2]
This totalled around 12 miles (19 km), with the longest single length being just over 4 miles (6.4 km). The third construction type was the use of either bridged aqueducts or inverted syphons to cross valleys and rivers where the ground level dropped too steeply for the required hydraulic gradient to be maintained. The pipeline was continued at ...
