Apparatus and method for accommodating and handling excess deliveries of combined sewage overflows to a sewage treatment plant supported and contained within an off-shore moored vessel or platform, by diverting the excess deliveries to ballast tanks for temporary displacement of clean ballast water and to be returned to the treatment system when excess deliveries of combined sewage overflow are relieved. Fluids contained within the ballast tanks are utilized to provide buoyant support for process tankage. Baffles within the ballast tanks minimize underisable mixing of the combined sewage overflows with the resident clean ballast water.
