CFC cooling water usage

[ExHempKnight]

To those with counter-flow chillers... Does anyone know roughly how much water it takes to cool a 5 gallon batch?

I have a 20-foot copper-tube-in-rubber-hose CFC, and I would like to save the cooling water for cleanup after a brew session. Normal city water pressure supplies the cooling-water side (wort will be pumped through with an LG 3-MD-MT-HC 500gph pump, if it matters).

I realize that cooing water temperature plays a large part, but I just need a ballpark number so I can get an appropriately sized tank.

I'd buy a large 50G rain barrel if you want to save it all. If you only want to save it for cleaning, then fill a 5G bucket and let the rest run down the driveway.

I realized that I wasted a lot of water yesterday I attempted to save it, but it filled my plastic tote up very fast. I am thinking of using a pond pump or some other pump. I would use my Chugger to pump ice water through my system and into a tote I'll then pump from from the wasted water tote back into the ice tote.

living in AZ wasting water is a big NO NO.
