Hi,

I am having difficulties in H2OMAP modeling water age for a system that alternates the system water source weekly. The first week water enters the system system directly through a PRV. The second week water enters the system by filling a ground storage tank which is then pumped into the system as needed. The third week it pumps directly into the system again (with the water in the ground storage tank stagnant for the week).

I can run either source scenario separately; however, I don't think that is an accurate representation of the system as it does not account for the age of the water in the ground storage tanks during the week it is not pumping.

Any suggestions on how to model this system?
