Description Of Incident: Last night, 8.11.2020, during a massive thunderstorm Burlington Main plant switched over to emergency power during a power outage. During that time the CSO sodium hypochlorite disinfection pumps did not cycle on due to a fault caused by the electrical disruption. Two staff members were on site and immediately went to fix the problem. Within 13 minutes the pumps were activated and full disinfection commenced. We will continue to investigate why these pumps did not actuate correctly. The dry weather process was not affected by this failure.
