A conduit system for transporting municipal or industrial wastes economically and efficiently is shown. The conduit system comprises a conduit which is located within a body of water and which has a thin, flexible wall adapted to maintain the contents of the conduit in pressure equilibrium with the body of water in which the conduit is situated. By maintaining pressure equilibrium or a slightly higher pressure within the conduit, it is possible to make substantial savings in materials of construction; and by locating the conduit within a body of water, substantially less cost is incurred for right of way. The thin, flexible wall of the conduit maintains the pressure equilibrium whether the conduit is ballasted to the bottom of the body of water or supported at an intermediate location by buoys. Liquids or liquids with entrained solids are transported through the conduit by flow augmentation means positioned at intervals along the length of the conduit. Desirably, these flow augmentation means comprise axial or centrifugally acting impellers adapted to shred debris typically found in municipal or industrial waste. The internal surface of the conduit may be provided with helical flutes or similar contours to impart a swirling motion to the fluid passing therethrough.
