Flexible walled conduits and flexible walled enclosures which are adapted to contain fluids at pressures in substantial equilibrium with the pressure of a body of water in which the conduit or enclosure is positioned are discussed. Particular attention is directed to the physical configurations and structure of enclosure for containing municipal and industrial sewage and particularly for segregating the solid matter contained therein and treating the biological matter contained therein. Apparatus is shown for segregating solid debris by means of buoyancy characteristics and for removing both heavy and light solids into enclosures from which they can be further processed, recovered or eliminated. Large, flexible walled enclosures called equipods and equiponds are disclosed, as are their combinations, in systems which are adapted to treat municipal sewage and utilize the biological processes. Details of large storage vessels having flexible walls and adapted to be used at sea for processing sewage are discussed in detail.
