The flow rates are moments in time, and can be affected by various circumstances, such as pump changes or valve position and therefore not unusual to have higher or lower than normal flows.

Comparison of Actual to System Approved Flow

Flow rates as set in the Municipal Drinking Water Licence # 007-104 and Drinking Water Works Permit # 007-204.

Maximum daily flow: 65.000 ML
Maximum flow rate: 65.000 ML/day
Maximum daily flow - during construction 81.800 ML
Maximum flow rate - during construction 81.800 ML/day

The percentage of rated capacity has been calculated based on the maximum daily flow during construction for January 1, 2016 – December 31, 2016
