How To Drill A Well

Ok so what’s going on here and what’s all over the ground?
We’re getting ready to build a house on 5 acres and the first thing we want to do is drill a well.
It’s hard to budget for the cost of a well because you don’t know how deep you must go to get water, so I like to get this out of the way early.
The guys grabbed 20-foot sections of drill rod our of the carousel and thread them onto the previous piece.
They use non-polluting grease on the threads, so they won’t seize.
This rig uses 350 PSI of air to power a pneumatic rotary hammer to drill into the bedrock.
At 160 feet we hit a lot of water- Here’s how they measured the gallons per minute: They created a damn around a section of PVC pipe so they could fill a one-gallon container with water.
We timed how long it took to fill- 2 seconds. 60 seconds divided by 2 seconds is 30- that meant we had 30 GPM.
I made this drawing to explain how it went- They hit bedrock at 20 feet down, at this point they put in a piece of steel casing.
They drove the casing into the bedrock to make a seal. The casing keeps surface water from leaking into the well.
Next, they drilled down to 160 feet where they hit a lot of water- this company always drills a minimum of 200 feet, in case there’s a drought, we’re more likely to still have water.
Let me know in the comments -how much do you think this well will cost? @hausplans
