IAPMO Water Demand Calculator

I’m just learning about the IAPMO Water Demand Calculator. Has anyone been using it?

It looks like it uses Hunter’s Curve, which as we have been saying for decades now, overestimates. But that is code in most locations. So our recommendation is, design to the code, but understand that you already have 40% redundancy. Don’t add any more! And make sure that the pump you select can handle the low flows. Pressure tanks help this, a lot!

We had such a great experience building tanks in the Columbia, SC, area, and Asheville, NC, area, that we want to do more! Georgia Water Tanks is now serving an expanded area, for some of our manufacturers. Please contact us if we can help design or bid on water tanks in central or western Carolinas, east Tennessee, and central or northern Alabama.

Small Rainwater System for Parking Deck

This one was small enough that a day tank was unnecessary. What we call the “straight shot” design is appropriate up to 50 – 100 GPM. The limiting factor is how well the UV handles heat during periods of inactivity. As the UV manufacturers move to LED bulbs, we expect them to do a better job.

I wish this valve was here instead!

Rainwater design recommendations change every couple of years, so contact Georgia Water Tanks for the latest.
