ABSTRACT:
One or more thin-wall tubes called "equiducts" are located near or on the bottom of a body of water such as a lake or ocean, or, more typically, in a water artery such as a river or stream. When the tubes are used for waste transport along a river, communities and industrial plants discharge their sewage and other wastes into the tubes at various locations along the river. The liquids in the tubes are in fluid equilibrium with the surrounding water, so that the tube walls can be thin and made of relatively inexpensive materials. The liquids are carried downstream in the tubes by the natural grade of the river bed, and by pumps located at spaced intervals on the river bed. The liquids are conducted to one of several different disposal arrangements. One disposal arrangement is a conventional on-shore processing plant. Another is simply a deep-water disposal site far out into the ocean or a large lake at the end of the river. A third disposal arrangement is a floating or underwater processing plant, either on the bottom of the river, ocean or lake, or floating on the surface of such a body of water. Alternatively, the wastes can be processed in transit in the tubes. Preferably, separate tubes are provided for different wastes so that each can be treated by the process most effective for the type of waste involved.
