His reasoning for the pump depth had something to do with the size of it (hp) and the standing water level. Meaning he felt a 2-½hp pump would not stress lifting/pumping from where he set it. (I guess) Also, he used a Ø6" steel casing set directly into the granite. The first 12' - 15' had Ø12" steel casing around the 6' and filled the gap with concrete.
We were told that indeed, we were fortunate to have that amount of water available. However, in the South Fork area of Three Rivers, CA almost all the well are over 25 gals/min. Someone he just did was a gusher...like a billion gals/ min /forums/images/graemlins/grin.gif(more like 200) but a lot more than ours. Our direct neighbor got 80 gals/min and he is below us about 200' in elevation. Funny thing there, he had to go almost 400' down there too.
I don't know how he manages to certify his wells other than he drill almost ALL the wells in our area for sure and many many in the rest of Tulare County.
When his dad started out, he remembers drilling in Los Angeles, Riverside and out where I live in Rancho Cucamonga and even out to Temecula. But the brothers now stick to the local area as they are so busy with referrals. It's funny, their office is in Lemon Cove, about 10 miles down the hill from us and the building is ...no kidding...about 15' x 20' max! I don't know if it's got a bathroom in it or not. Of course they have a larger office in Exeter.
They came very well reccomended and sure delivered. When we first met them, they walked the property and asked where we planned to build our home. Then looked up and down this ridge for about 5 minutes and said, you could put the well up along tis ridge anywhere above the house. Better up there by that Oak. Heck, after we did all that water-witching, we couldn't have been more than 25-30'' from the spot he reccomended! Those guys were amazing!
Attached is a pic of them drilling. You can see all the grey granite.
