Description:
On Sunday, October 14, 2007 the Rockfish Creek WRF experienced an equipment failure that caused
wastewater to back up in the collection system and eventually resulted in an SSO on the morning of
October 15, 2007.
Corrective Measures:
The overflow was stopped by placing standby bar screens and screw pumps in service to help quickly
relieve the backup of wastewater in the collections system. The failed equipment, a 1/4 inch
mechanical bar screen, is monitored by our SCADA system but an audible alarm was not transmitted
