The correct answer is: A. Inverted syphon<\/strong><\/p>\n An inverted syphon is a type of sewer pipe that is used to carry wastewater under an obstruction, such as a road or railway. It is a curved pipe that is buried underground, with the ends of the pipe above ground level. The wastewater flows through the pipe by gravity, and the curved shape of the pipe helps to create a vacuum that draws the wastewater along.<\/p>\n Inverted syphons are often used in areas where there is a lot of ground water, as they can be installed without having to dig deep trenches. They are also used in areas where there are a lot of obstructions, such as roads or railways.<\/p>\n Depressed sewer and sag pipe are both types of inverted syphons. A depressed sewer is an inverted syphon that is used to carry wastewater from a higher elevation to a lower elevation. A sag pipe is an inverted syphon that is used to carry wastewater across a valley or other low-lying area.<\/p>\n Inverted syphons are a safe and effective way to carry wastewater under obstructions. They are also relatively easy to install and maintain.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Inverted syphon” option2=”Depressed sewer” option3=”Sag pipe” option4=”all of these” correct=”option1″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[650],"tags":[],"class_list":["post-7682","post","type-post","status-publish","format-standard","hentry","category-waste-water-engineering","no-featured-image-padding"],"yoast_head":"\n
