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 from the Hobart Diversion Reservoir and a second inverted siphon were completed in ...
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).
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.
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 ...
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]
[77] [119] This installation provided filtered water for every resident of the area, and the network design was widely copied throughout the United Kingdom in the ensuing decades. The Metropolis Water Act introduced the regulation of the water supply companies in London , including minimum standards of water quality for the first time.
The system consists of about 83-mile (134 km) of buried concrete unpressurized conduit and 9.9-mile (16 km) of buried pressurized inverted siphons. Over its length the aqueduct crosses eight rivers. The conduit was built using the "cut and cover" method with an unreinforced concrete arch resting on a cast in place base invert.
The pipe traversed the Washoe Valley in the form of an inverted siphon, at the lowest point having a pressure of 1,870 ft (570 m) of water, [2]: 120–121 or 810 pounds per square inch (psi) at the design flow. The inlet being 477 ft (145 m) above the outlet, the water was forced through the pipe at tremendous pressure.
