Pattern usage questions.

WaterCAD V8i Series 5

I'm having a tough time wrapping my head around Pattern usage.  It seems there are at least 3 different ways that patterns can be applied: 1) Demand Alternatives, 2) Customer Meters, and 3) Calculation options.

My model has all the customer meters in it, with each meter assigned to its appropriate junction.  The "Demand (Base) (gpm)" column is populated with each meter's ADF (in gpm).  What I want to do is apply a Peaking Factor to the customer demand.  I have created a pattern called "Max Day".  It seems more logical (to me, anyway) that if I want to apply a multiplier to all customer usage, the best place to do that would be in the "Customer Meter" Flex table.

I have a diurnal curve set up as a pattern, as well as having Simple Controls for my pumps and am using the "EPS-Snapshot" feature (in order to use patterns and controls).

Can anyone shed some light on the rationale for having multiple places where patterns can be applied, and under what circumstances to use each place?  Is there a preferred or suggested way to apply patterns to customer meter demand?  With having so many options regarding where and how to apply patterns, it can get confusing pretty quickly.  I would like to keep it simple and as intuitive as possible.

Thanks in advance!

  • Hello Gary,

    The patterns that you specify at the Customer Meters or Junctions (if you are not considering Customer Meters) are generally the Diurnal curves which are the usually the 24 hours consumption patterns for a node or customer meter.

    If you want to apply a Peaking Factor then the same has to specified in the Calculation Options in WaterCAD under "Demand Adjustments". This option is usually used to assign (multiply, add, subtract or divide) a common factor for all demands.

    I am sharing an article which discusses the different options to view and edit demands;

    Viewing and global editing a list of Demands

    The demands or patterns you assign in the demand control center or individually at junctions / customer meters should show up in the demand alternative. Here is another informative article above using the demand control center;

    Let me know if this helps.
