    A while back, someone posted some pics of a well just over 100 feet in depth that was cased in 2 inch Schedule 40 PVC pipe. Water was pumped from this well by means of a 1/2 inch air line that went to the bottom of the well. Air, from a compressor, lifted the water and from there it filled a 300 gallon tank. It was delivered to his house by a submersible pump in this tank, with a bladder tank just outside of the storage tank.

    Several posters reported that this system was good in areas where wells had a lot of sand in them that could damage the impellers of a submersible pump. They also said this system was good for wells with high concentrations of soluble iron and manganese and hydrogen sulphide, as the air would oxidize these contaminants and remove them from the water.

    The question I have is this, would this type of system still deliver as much sand into the storage tank on the surface, or would the sand tend to fall back down the well before it reached the surface? If the same amount of sand was delivered to the storage tank, there doesn't seem to be much advantage, as the impellers in the tank's pump would suffer too.

    The sand would settle to the bottom of the tank. The intake on the submersible would be kept up off the bottom.

    Thanx for that answer. Does anyone else have any experience with this type of pumping system? There is a hand driven well near here with iron, manganese and H2S problems that may be ideally suited for this type of system.
