Description Of Incident:

Rapidly melting snow created high flow conditions that were outside the normal operating parameters of the facility. Increased flows potentially reduced disinfection time in chlorine contact tank. A chlorine residual of 1.30 mg/l was recorded along with the dispensing of 7.8 gallons of chlorine.
