Water is pumped from the pump house up to the Ag Water Tank (Redwood tank) for our agricultural water and fire hydrants, as well as to a 2500 gallon sealed "Upper" tank located above the sand filter system. The water flows down at a rate between 1 and 3 gallons per minute to the 250 gallon Sand filter (a flow that is faster than that will not clean the water properly). From the bottom of the Sand filter tank the filtered water flows into another 250 gallon tank and a valve that can be turned on or shut off. Then from the sand tank filter system, the water is carried into the top of the 2500 gallon holding tank. From the holding tank the water goes through a series of pipes into each of our units.

The sand filters the water, and in addition, a layer of large microbes forms at the top and, with oxygen, they grow and eat pathogens, including parasite eggs, etc.

Ag water flows from the the Ag Water (Redwood) tank to our residences in a separate piping system.
