So once they install a pump they can test pump it to see how many GPM it makes?

The rotary well drilling stuff is all new to me. All I know is cable tool.
I'm just surprised they leave an inch gap around the casing to potentially cave in and drop down to plug the perforated portion. Not sure what the underlying soil and rock conditions are, could very well be fine.
I agree thats you won't be able to get an accurate refill rate till you get your pump installed.

As we're just finalizing our #'s for building, it's amazing as I've read several of these well building threads how different the pricing is!
Our specs are ESTIMATED to be as follows:
Drilling & Steel 6" Casing: $42.00 per foot
Bedrock Drilling: $22.00
Drive Shoe: $110.00
Sealed Well Cap: $97.00
State Permit: $65.00
Minimum Charge: $2,500.00 (down payment in advance: $2,500.00)
I think I've seen some of you @ $10 per foot!

You got one heck of a well, and unless your planning on watering 100+ head of cattle, you'll have plenty of water for several average households! 1-2 gallons/minute will work fine with 100' of storage (in the hole).

WOW - 20 GPM!!! That's enough for irrigation. My 5 gpm is enough for my 100+ head of cattle.

No cattle for me. :laughing:
At first I thought 20gpm was low but the more I read comments from people, the more I realize that's good water production.
The well should hold over 100 feet of water.
I found it interesting that they put in five 20' sections of perforated PVC pipe but they alternated them every 20' with a solid PVC pipe. So between 500 feet and 300 feet there is a 20' section of perforated pipe.

Think about it this way. We built a 4 bedroom house and had an extra-large septic system installed. It rates for 350 gallons per day. That is just a hair under 0.25 gpm. This is all of the water a sizable family needs to live on.
Now irrigation or other outside uses may well increase the amount one draws from a well, but if you can average 0.25 gpm you can live on it.
20 gpm is a magnificent flow rate.
We have 2.5 to 3 gpm, water about 1/4 acre of landscaping and have more than sufficient water.

In my area that would be considered low rates.
My well is 180' deep 6" steel casing, 20' perforated pipe. Pump sits at 156', water is 50' down from wellhead. While drilling the truck was pumping over 100 gallons a minute without the level in the well dropping. I wanted to go down 300' but the driller (trusted friend) said if it was his own well he'd stop at the 180'. He was in a big gravel bed and he said it acts like a filter. I have had no problems of any kind, the well is about 17 years old. The water is crystal clear and cold. Every once in a while there is a slight sulfur smell. Overall I'm very happy with the well.
I would suggest a Y strainer and filter to anyone with a well.

can some one explain this perforated pipe? i would think it would cause issues with air getting in and stuff, i can see it at the bottom below the pump but i don't understand why it would be above it at all
