Description:
In the past, the operator of a sewage collection system has had three alternatives for dealing with overloaded sanitary sewers; ignoring them, diverting them to storm sewers and streams, or pumping to other locations. An EPA-sponsored research program entitled, 'Polymers for Sewer Flow Control,' Contract No. 14-12-34, suggested a possible alternative system wherein the capacity of a sewer might be increased by the injection of certain water-soluble chemicals to reduce turbulent friction. This concept was further developed and demonstrated during this project, EPA Grant entitled, 'Elimination or Reduction of Sanitary Sewer Overflows in the Bachman Creek Sewershed,' which was executed in Dallas, Texas. This report was prepared to help operators of sanitary sewage collection systems determine the feasibility of using turbulent friction reduction, designing an injection facility, choosing a friction reducing material, and evaluating the results.
