Am here in central Oklahoma and have some questions on PVC well casing.
First, I have a well driller that will drill me a new 250 foot well, but I need to provide PVC casing, submesible pump, etc. Our geology is lots of sand, gravel, some caliche with lots of water bearing gravel 30-60 foot down.
Existing 160 foot well is drawing air with high demand so I need a new well. The new well is for both home use and farm use (irrigation, watering livestock etc).
A few questions . . .
Is four inch schedule 40 (20 foot with bell ends) OK? Or is schedule 40 overkill in erms of thickness?
Rather than using a screen, I have seen drillers cut narrow slits in PVC wall with hacksaw in the first couple of pipes to allow water into casing. I know to backfill the borehole after liner is in with fine gravel. Is this slit techniqe OK?
Thanks in advance,
Steve
