Sanitary Sewer Overflows (SSOs)


In April 2014, the Massachusetts Department of Environmental Protection (MassDEP) revised the statewide Regulation 314 CMR 12.00 Operation, Maintenance and Pretreatment Standards for Wastewater Treatment Works and Indirect Dischargers (PDF).

Sections 12.04(2)(a)-(d) list specific requirements regarding infiltration/inflow reduction. The Regulations reference MassDEP’s Guidelines for Performing Infiltration/Inflow Analysis and Sewer Systems Evaluation Surveys (May 2017, PDF).

The New England Interstate Water Pollution Control Commission (NEIWPCC) developed a manual Optimizing Operation, Maintenance, and Rehabilitation of Sanitary Sewer Collection Systems (December 2003) as a guidance document for collection system owners, managers, and operators. The manual was developed using a grant from the US Environmental Protection Agency.

Also available from NEIWPCC is the Illicit Discharge Detection and Elimination Manual – A Handbook for Municipalities.

The United States Environmental Protection Agency New England (USEPA Region 1) has a variety of wastewater collection system resources including its Wastewater Collection System Toolbox web page.
