JB&B Consulting Engineers 345 Park Avenue New York, NY 10154 Rockefeller Research Laboratories, Borough of Manhattan Att: Mr. Ri Benazzi Gentlemen: Please refer to your letter of September 4, 1987. The installation of an inverted siphon in East 67th St., for the purpose of lowering the existing IS" 0 combined sewer is unacceptable to this Bureau.
Inverted siphons in general and especially on small diameter sanitary or combined sewers, create hydraulic maintenance and odor problems. The use of an inverted siphon is not a viable solution to your interference problems.
Very truly yours,
MAGDI FARAG, P.E., CHIEF Division of Sewer Regulations &. Control, Bureau of Sewers
