Sewage Discharge Reports

DEC receives current sewage discharge reports from the municipality where the discharge occurs by email from NY-Alert. Notifications for the last 7 days are located on the Recent NY-Alert Sewage Spill Notifications webpage

Historical data is retrieved from NY-Alert in batches and can be viewed in the Excel spreadsheet, Sewage Discharge Reports (Excel,155 KB). This spreadsheet is separated into multiple tabs as changes have been made to the data collection methods. These tabs contain the following information:

  • "PDFs through May 2015" - data from May 2013 through May 2015 which was submitted to DEC as PDFs.
  • "NYAlerts through 5_10_16" - data which was received from NY-Alert from February 2015 through May 2016.
  • "NYAlerts from May 2016 through May 2017" - data which was received from NY-Alert from May 2016 through May 2017 which is unedited.
  • Future tabs will show unedited data received during the listed time frame.

Data Caveats

  • All data is submitted by the POTWs and POSSs.
  • DEC does not issue notifications about individual discharges.
  • The reports are submitted by the notifiers creating the reports in a short time frame after discovery of the discharge and specific details may not be known.
  • Data is estimated based on the existing systems, models, and personal knowledge of the sewer systems.
  • Data quality is not checked by the DEC.
  • The NY-Alert program allows for negative durations and zero quantities for volume.
  • Background system processing on duration calculates to the next whole hour.
  • Addresses may not be entered by the notifiers in a way that allows the parts of the address to be separated.
  • Multiple notifications may be entered for the same discharge since municipalities need to submit daily and termination reports for ongoing discharges.

Description of information required to the extent knowable using existing systems and models

Date/Time of Discharge - approximate date and time that the discharge was discovered
Location of Discharge - location should be as detailed as possible, but options include: name of receiving waterbody, closest street address or defining landmark, GPS coordinates
Duration of Discharge - estimation of expected duration of discharge at the time the report was submitted
Volume of Discharge - estimation of the volume of discharge
Treated State of Discharge - either Untreated, Primary Treatment with Disinfection, Primary Treatment without Disinfection, or Other with explanation
Reason(s) for Discharge - information about why the discharge occurred
Description of Corrective Action(s) - brief summary of preventative or corrective actions taken in response to discharge

Combined sewer overflows (CSOs) may discharge untreated sewage when it rains

Find out if you live, or recreate in a CSO community (open the map link below). For more information about CSOs visit DEC's Combined Sewer Overflow (CSO) web page. For more information about the wet weather advisory, visit the CSO Wet Weather Advisory web page.
