  Seminar Publication, National Conference on Sanitary Sewer Overflows (SSOs) (602 pp, 9.16 MB) (EPA/625/R-96/007) September 1996

The National Conference on Sanitary Sewer Overflows was held in Washington, DC, on April 24–26, 1995. The conference was a forum for nearly 500 environmental professionals to exchange technical information and experiences relating to the complex issues of sanitary sewer overflows (SSOs).

Thousands of municipalities across the nation are serviced by separate sanitary sewer systems. A chronic problem that faces many of these systems is the occurrence of SSOs. SSOs are caused mainly by the infiltration and inflow of wet-weather flows and blockages and flow restrictions in the sewer system; they pose a risk to public health and the quality of our nation’s waters. This conference was held to bring together individuals from across the country to discuss the technical and institutional issues related to SSOs. The conference examined a variety of topics relating to the regulation, analysis, evaluation, management, and control of SSOs. The presentations at the conference and the selected papers in this document address the following:

  • Background and problem definition
  • Modeling and assessment
  • Institutional issues
  • Dealing with private service laterals
  • Data collection and analysis
  • Case studies
  • Storage solutions
  • Watershed and regional approaches

This document presents selected peer-reviewed papers from the conference. The purpose of the document is to share the information presented at the conference with individuals who were unable to attend. This document will be useful to individuals who are currently facing the complex issues related to the management and control of SSOs. These individuals include environmental regulatory personnel at the federal and state levels; decision makers and technical personnel from regional and municipal wastewater management authorities; private sector personnel, including environmental consultants and equipment manufacturers; university professors, researchers, and students; and other interested persons.

The goal of sharing this information with a broader audience is to help environmental professionals and others to better understand the complex institutional and technical issues relating to SSOs and to assist environmental decision makers in making cost-effective decisions.
