For the gas well, you have something like this(not mine) sticking out of the ground.
Called the gas company to get approval to utilize my free gas and then bought the appropriate regulators and fittings along with 500 ft of 1 1/4" black plastic pipe to run to the house. Dug a 4 ft deep line all the way to the house and buried the pipe. At the house, you have another regulator and shut off and then it goes into my house the same as gas from a utility company.
The gravity spring has a cement 3 ft x 4 ft box about 500 ft on the hill above the house(about 40 ft of elevation). It was here before I bought the place but it looks like the basin was simply a dug out area where there was a spring on the hill and a simple concrete form was put in to hold water seeping from the spring. From the concrete box, we have 3" pvc pipe that runs about 250ft and then we neck down to 1 1/4" black plastic pipe(to create pressure). Then at the house we neck down once again to 3/4" pvc then 1/2" to supply all our water. No need for any holding or pressurized tanks and since the water is clean spring water, no need for any filters. Pretty easy set up once you've done it once.
