well water recovery formula...

[tws]

greetings,

i'm looking to find the recovery rate of my well...

with a 60psi gould pump i drew down my well level to 104 inches - measured from the top rim. where it stays at over 2 hrs of pumping.

when i turn off the pump it takes 8 minutes to recover to the depth of 79 inches - measured from the top rim.

a difference of 25 inches.

my well is 153 inches deep.

and has a diameter of 30 inches.

can i discover any info from these figures?

thanks.

Your well recovered at just under 10 gallons per minute.

Thanks Phishfood!

I'm confused by the 60 psi Goulds pump. What is the pump putting out in gallons per minute? That would be a more useful number to work with.

i think i recall filling a 90 gallon stock tank last summer and timed it at approx 12 minutes.

but you're right a measure of how many gallons per minute would be useful.
