Abstract

An underwater discharge system for discharging an effluent overboard through an aperture in a wall of an at least partially submersed structure. The effluent is discharged through a conduit into a pressurized chamber which is open to and extends below the surface of the water in which the effluent is to be discharged. The pressure in the chamber is maintained to sustain the level of water in the chamber below that at which the conduit enters the chamber. A tubular catchment for transporting the effluent to a location remote from the structure is positioned to have one end within the chamber, above water level, open to the chamber's atmosphere, and sized and arranged to receive the conduit within its opening. Pressure within the chamber is maintained to keep the effluent from spilling over the one end of the catchment into the water in the chamber. The other end of the catchment communicates with a discharge basin which transports the effluent to the remote location.
