Status: offline 		Reverse osmosis units as shown in post #10 do work but require a lot of continuing maintenance. Some have been in operation since the 1960s in the Arabian Peninsula. I remember propositions in the 70s to build one for the Los Angeles area. The problem was that the throughput of a massive plant was still minimal compared to the demand for the area.

For an industrial area that has waste heat to spare; distilling plants work better. (Ship board, de-salinization is usually by distilling plants. Boiling the water at sub-atmospheric pressures gives a quite good throughput.)

Has anyone seen a commercial solar de-salinization plant done on an industrial scale? Those work quite well on a science fair or emergency water supply basis but I haven't run across one at commercial scale.

Phoenix Area and the Palo Verde nuclear power complex is a case of a good idea that just doesn't have the resources close enough. Only four of the planned 12 reactors were ever built at Palo Verde. Why? Because the population of the Phoenix area grew so fast that the aquifer could not support cooling water for more reactors. A bit of a shame as, when they first broke ground, a completed Palo Verde Complex could have provided electric power to the whole Southwestern area.. San Diego and Los Angeles included.

0.82 inches and rising according to weatherbug


I'm not familiar with that region's water supply and usage as I am for New England (go figure I live there). But I do know each area needs 'x' amount of water in the year to keep the environment (and environmental factors) constant. We dont get enough snow in the winter, rain the spring and good heat in the summer; there are a number of negative effects that can take place. We in the six states feel it in each season depending on circumstances.

While 0.82 inches might be awesome for Death Valley, its the death of the cranberry industry in Maine! So the question I have, is, were does the amount of rainfall stand for the current year in that area to-date? Has the area gain more, less, or about the same needed for the area?


Joe I have lived in the deserts of AZ, cali and north africa. No matter which you choose, an eigth of an inch can run 3 foot walls of water down that dry wash. I am 35 miles from the Colorado river and 70 from Lake Meade Our water goes there. Please note I said wall of water. Rain is deadly here no matter how little.

I moved in to established beds in 2004. Xeriscaping is what people use. We get about 10 inches of rain spread over 37 days a year (including what we call Monsoon season). we don't grow any major crops but know which desert plants and animals to both avoid and eat.

This is what is done to us when it rains. Especially a hard rain. I never travel during the rain in the desert. Way to dangerous. I have seen water, 4+ feet and more, running across our roads.
