Abstract: A numerical model was built in order to analyze the performance of project alternatives, to update the central sewage system of the Metropolitan Area of Buenos Aires, regarding water quality of the coastal zone. Water use criteria were developed, by defining maximum concentration values for a set of representative water quality parameters. Presently, a strip with a variable width of a few kilometers, adjacent to the coastline, is not apt for any use. The model shows that: (i) a long extension of the coastal zone will be recovered for Secondary Contact Recreation; (ii) a significant reduction in width of the zone limited for Drinking Water by Conventional Treatment will be achieved; (iii) no further recovery for other uses of the coastal strip will be possible if pollution management plans are not implemented at least for the other two major urban watersheds contributing to pollution; (iv) relatively large limited use zones will be developed around the proposed outfall outlets; (v) secondary treatment of the outfall effluent would be superfluous.
