RJN Group, Inc. offers infiltration and inflow (I/I) and sanitary sewer overflow reduction programs.

The key to a successful I/I flow reduction program is accurately determining the amount of I/I entering the sanitary sewer system and identifying the sources. RJN has developed techniques to accurately determine the amount of I/I entering the sanitary sewer system and identifying the sources, they include:

  • Continuous depth/velocity flow monitoring
  • Manhole/visual pipe inspection
  • Intensive dual blower smoke testing
  • Internal/external building inspection
  • Dyed water flooding
  • Enhanced internal TV inspection

    RJN Group, Inc. continually enhances the Computer Analysis of Sanitary Sewers (CASS) series of computer programs that:

  • Calibrate the inflow-rainfall relationship techniques developed by RJN
  • Model individual I/I sources within an entire collection system
  • Link I/I source defect modeling and collection system hydraulic modeling to facilitate the elimination of SSOs.
