Infiltration Gallery Wells Capture and Store Upper Ground Water . . . Just getting the stuff to the site is a job . . . See the trickle of water? This well actually provides an honest 1 GPM of water - or 1440 gallons per day. Ready to set the pre-built well into place. Filling around the well with 1 1/2" to 2" gravel that also stores water. We figure this well has about 1500 gallons of storage. On top of the gravel, we put 6 mil plastic and then bentonite chips. This seals the upper clay backfill from the gravel, and also seals the water in the well from surface water. Getting close. The pipe with the green tape is the pump access casing, and the other thing sticking up is the frost free hydrant. This is the pump and the pitless that allows the water to make a 90 degree turn about 5' down to your water line. This prevents the water from getting near the surface where it could freeze. I want to simply take a bow at this beautiful gallery well completion. We've earned how to rig these wells to control them as they are installed. Got it down after over 20 years! Another gallery well to last the test of time. "Dude - get the other end of the well a little more to the right!" :) The plastic covers the gravel to separate the surface water from the upper ground water. We've figured out that the most efficient way to install underground work is three people. One in the excavation, one on the ground getting tools and parts, and one in the excavator. We don't charge extra if the well ends up with a view :)
