DESIGN AND CONSTRUCTION OF THE BOSTON OUTFALL

Y. Eisenberg, P. Brooks

Abstract


The Boston Outfall, presently under construction in Massachusetts, U.S.A., is the world's largest tunnel outfall. The outfall represents the latest in tunnel outfall technology and when completed will discharge up to 1300 million gallons per day of secondary treated effluent through a system of seabed diffusers, nine and a half miles off the coast of Boston. Installation of the 55 diffusers and risers are nearing completion, with the construction of the outfall tunnel just commencing. The Outfall is a major component of the Boston Harbor Clean-up Project. This paper presents a description of the design and construction of the deepwater Boston Outfall.
