Occipital Headache. Occipital headache is a type of headache that occurs in the back of the head, specifically at the base of the skull. It may be the cause of your headaches and neck pain. If you have a history of migraine, sometimes a headache in this area will provoke a migraine. The pain is usually a dull throbbing type of pain and if this occurs then it is a type of tension headache.
1 Drilling the well hole, installing the casing (a tubular lining that prevents the well hole from collapsing) and adding a well cap (a tight-fitting, vermin-proof top seal) typically costs $15-$30 per foot, or $1,500-$3,000 for a 100' deep well, and $6,000-$12,000 for a 400' well. This brings the typical total for drilling a well and setting up a private water delivery system to $3,500-$20,000 or more, but an especially deep and difficult well with a complex water system can cost $20,000-$50,000 or more, depending on depth, water yield and system complexity.
The cost of building a new water well is derived from the amount of casing (20 foot minimum) to bedrock and the amount of drilling needed to find water, plus the cost of the drive shoe and well cap. In unstable formations we use our underreamer system which drives the casing and drills at the same time.
