The UV disinfection process.
Cause or Reason for the Upset/Spill/Bypass:
At 1 : 12 pm on July 20th we had a drop in voltage coming into the City
of High Point' s Eastside WWTP. This caused the main breaker for the
ultraviolet disinfection system to trip causing the UV system and
effluent flow meters to shut down. We reset the main breaker and
restarted the UV system at 1 : 24 pm. Once the UV system restarts, it
takes seven minutes for it to be fully operational . As a result, we had
nineteen minutes without disinfection . The flow when the breaker

maximum of 229, 000 gallons bypass the UV system.
