Design daily flow (Q)
It is preferable to provide equalization or off-line storage facilities to allow for
constant application rates and short-term storage during power outage or
extremely heavy precipitation. The design daily flow should be based on peak
seasonal average daily flow. For systems without such storage facilities the
design daily flow Q should be based on the average flow during selected period
depending on the flow conditions.
