A12.0 System or User Profile and Demand Curve

The System or User Profile and Demand Curve allows you to preset your estimated monthly usage peaking factors by entering data and setting the controls in the orange cells shown below.

The peaking factor of a system, a user, or a source of water is a very important value to know and model. It tells the supplier the difference or extent of a peak month or day demand (PDD), as related to an average day demand (ADD) calculated typically over a year. By knowing the peaking factor and related annual profile of a system, a source can be better provided to meet the demands of the system.
