It has been proposed to constructoutlets for the Passaic Valley sewerin New York Upper Bay, conical inshape, diverging upward and with aspiral flange on the inside for the pur-pose of delivering the sewage in theform of a thin hollow cone. This, itwas expected, would provide a largesurface of contact with the bay Avaterimmediately after discharge. Another feature of the Passaic Val-ley outlet is in providing multipleoutlets.

Another example of multiple outletsis in the new outfall at Cleveland,where seventy million gallons are dis-charged daily a half mile from shoreat a depth of thirty feet from S^-inchlioles, spaces seven and one-half feetapart on each side of the tapered out-let pipe and forty-five degrees abovethe horizontal diameter.
