[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 ...
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]
The last 3 km was unusually built using a pressured pipeline as an inverted siphon across a valley. At Arci is the venter of the inverted siphon, an embankment 12 m wide and over 130 m long increasing in height with the valley depth and at the deepest point was a bridge with arches carrying the pipes to reduce the depth of the siphon and hence ...

It included 15 inverted siphons that covered a distance of 6.13 miles (9.87 km). A tunnel 0.7 miles (1.1 km) long also made up part of the ditch. The remainder was open canal. The longest section of pipeline was a 7,961 feet (2,427 m) siphon that crossed the Chatanika River with a head of 544 feet (166 m).
