This report describes investigations of the oil trapping characteristics of inverted siphons as part of a demonstration program for preventing and eliminating oil pollution of the Buffalo River. An extensive study was made of the quantity and types of oil that accumulated in an inverted siphon located in the Buffalo sewer system at Memorial Drive and Gibson Street. Oil detectors developed under the program and their use for both automatic and manual measurement of accumulated oil depths are described. A telemetering system permitted oil data to be transmitted to a remote monitoring station located several miles from the siphon. The report discusses in detail the spectroscopic and chromatographic analyses of samples to characterize the nature of the trapped oils. Most of the trapped oil was of petroleum origin and was traced to spills of fuel oil at a nearby railroad terminal. The sampling program demonstrated that inverted siphons are nearly 100 percent effective for trapping surface oils and that the trapping efficiency for emulsified oil carried in the bulk water is extremely low. Described also are the results of tests made with 1/24 and 1/12 scale models of the Memorial Drive siphon based on both Froude and Reynolds scaling criteria.
