What happens in to the combined sewer during wet weather?

The City of Taunton has an EPA Region 1 and MassDEP permitted CSO located on West Water Street that outfalls into the Taunton River.  The City of Taunton’s Wastewater Treatment Facility (WWTF) has a SCADA system that monitors the City’s one permitted, active CSO.  When the SCADA system registers a CSO event an alarm is triggered. The flow meter at the CSO outfall records the flow rate and totals and trending on SCADA reports the start and stop time of the overflow event.

When the SCADA system registers an alarm, WWTF staff are required to go out on site to the CSO outfall to further verify that the CSO is active. From there, the final Combined Sewer Overflow Notification Plan will take effect.  Please see the City's Final Combined Sewer Overflow Notification Plan.  WWTF are required to file a report with MassDEP, https://www.mass.gov/how-to/sewage-notification-system
