Source of the Upset/Spill/Bypass (L ocation or Treatment Unit):
Clarifier scum pit and Chlorine contact chamber
Cause or Reason for the Upset/Spill/Bypass:
The wastewater flows from the secondary clarifier to the chlorine contact chamber. The cause of the bypass
occurred from the inlet slide gate to the chlorine contact chamber being closed. Contractors were on-site
painting the outside of the clarifiers and contact chamber. It is suspected that one of the painters knocked
the clamp off that was holding up the inlet slide gate to the contact chamber preventing the flow into the
chlorine contact chamber and through the effluent. The closed inlet slide gate caused the flow to backup into
the clarifier and the scum pit and subsequently onto the grounds with flowed into Cleghorn Creek.
