Background

During the Phase 1 of the City’s CMOM program the City’s eight inverted siphons were cleaned and inspected.
The siphons were constructed between the 1960’s and the early 1980’s. Six siphons are triple-barrel and two are
double-barrel comprised of various materials and diameters ranging from 6 inches to 60 inches in diameter.
Below is an inventory of the siphons inspected:
