Maximum Hour Demand -- The amount of water needed to satisfy the highest flow rate in awater system occurring for a one-hour duration.Peak Demand -- The maximum momentary load, expressed as a rate, placed on a water treatmentplant, distribution system, or pumping station. It is usually the maximum average load in onehour or less, but may be specified as instantaneous or for some other short time period.Peak Flow -- See Maximum flow.Period of Record -- The time span covered by a particular set of data.Aug. 29, 2003Page ii
