  • Sanitary Sewer Overflows and Peak Flows Listening Sessions (PDF) (32 pp, 1.3MB)

  • A brief presentation on sanitary sewer overflows (SSO) and peak flows.
    Date Published: 06/29/2010

  • CMOM Program Self Assessment Checklist (PDF) (166KB)

  • Screening-level tool that can help utilities evaluate Capacity, Management, Operations, and Maintenance (CMOM) programs and identify general areas of strength and weakness. Completing this CMOM assessment will allow the utility to flag CMOM program areas that need improvement and establish priorities for additional, more detailed assessments. In addition, the checklist will allow the utility to compare annual performance (e.g., percent of employees meeting training standards).

  • Summary of the August 14-15, 2002, Experts Workshop on Public Health Impacts of Sewer Overflows (PDF) (670KB)

  • In assessing the human health impact from sewer overflows in the US, initial research revealed that relatively little data were available that linked waterborne illness or other exposures to combined sewer overflows (CSOs) and sanitary sewer overflows (SSOs). In response to these challenges, EPA held a Public Health Impacts Experts Workshop on August 14 and 15, 2002. A group of nine external and EPA experts in public health, epidemiology, and wastewater treatment attended the workshop. Observers included representatives of stakeholder groups and EPA personnel. This workshop solicited individual opinions and provided a forum for information exchange related to this Report to Congress.
