Atmospheric pressure of about 14.7 pounds per square inch allows a “shallow-well” pump to “pull” water up from a maximum depth of only about 20 feet (Figure 2). However, if you know the pumping water level will be deeper than about 20 feet, then you must use drive pipe having a minimum diameter of at least 2 inches.

Correspondingly, how deep can you put a sand point well?

Speedbump is right, a well can be 100' or deeper and you could still pump water with the pitcher pump or a shallow well jet pump as long as it isn't over 25' to the pumping level.

How much does a sand point well cost?

Drilling a well costs \$5,500 for an average depth of 150 feet. Most projects range between \$1,500 and \$12,000. Expect to pay between \$15 and \$30 per foot of depth, or up to \$50 for difficult terrain. Digging might be enough for shallow depths, ranging between \$10 and \$25 per square foot.
