Had to drill a new well. Our old one was giving us issues. They started out in one spot. Hit a cavity and in the process of putting in the casing, it snapped at a joint and so they had to move to another location a few feet back. Drilling for it they hit probably the same cavity and the area around the rig sank a good 18". So they pulled the rig out and brought in dirt and were able to start back up. Took 5 days to drill this thing but now we have water. Got down to 145' and the pump is down at 60'. Water in the well is up as high as just 17' below the surface. They said it is about 80 to 100 gallons a minute. Now the fun begins for clean up around the well and getting all the dirt set up and grass planted. They hit my irrigation lines on the first attempt. Had to fix those. Thank goodness for slip joints. Made for an easy repair. Luckily they didn't get our internet cable that runs along the irrigation. Wife would not have been happy.
