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.

Claims

1. A liquid transport system for disposing of liquid waste from the land adjacent an inland water artery having a naturally sloping bed, said system comprising at least one flexible wall main conduit beneath the surface of the artery and extending in the direction of water flow along said artery, the liquid waste inside said conduit being in fluid equilibrium with the fluid outside;

a plurality of liquid inlet conduits for conveying liquids into said main conduit from positions spaced along said artery, said artery emptying into a larger body of water, merge means for coupling said inlet conduits with said main conduit for feeding said liquid wastes into said main conduit at a plurality of locations therealong;

pump means for safely augmenting the flow of liquid waste in said main conduit towards said larger body of water said pump means including flow augmentation means within said main conduit to augment safely the flow of said liquid wastes in one direction along through said main conduit without causing substantial departure from said pressure equilibrium for achieving dynamic stability of the flow of said liquid wastes through said conduit, and said flow augmentation means including means permitting flow of said liquid wastes therepast in the event of operating failures of said flow augmentation means; and

disposal means located in said larger body of water for receiving and disposing of the liquid waste from said main conduit;

the disposal means including a submerged processing plant submerged beneath the surface of said body of water and having means for carrying out treatment of said liquid wastes while said wastes are at fluid equilibrium with the larger water body and having an inlet thereof connected to an outlet of said main conduit.

2. A liquid transport system according to claim 1, wherein said wastes include bio-degradable wastes, and said main conduit includes means within it for biologically decomposing said liquid wastes while said wastes are being transported along said main conduit.

3. A liquid transport system according to claim 1 including means for conducting said wastes through a waste heat producing structure to absorb and remove the waste heat from said waste heat producing structure, and for then conducting the heated wastes back into said conduit for transport and disposal.

4. A liquid transport system according to claim 1, wherein said main conduit has a flexible peripheral wall and includes means for avoiding wave amplification in said peripheral wall during the transport of said liquid wastes within said main conduit, while the liquid wastes within said conduit are substantially in fluid equilibrium with the water of said water artery.

5. A system according to claim 1 wherein said at least one main conduit includes a plurality of dynamically stable, parallel, flexible-wall equiducts each of which carries a type of liquid waste different from that carried by at least one other of the equiducts.

6. A system as in claim 1 including means for controlling the buoyancy of said conduit to maintain it adjacent said bed.

7. A system as in claim 1, including means for comminuting solid wastes, mixing them with a liquid, and conducting the mxiture into the conduit, which conduit conducts said mixture through said inland artery of water.
