Back to LA and irrigation water....
20 some years ago, I had an interesting conversation w/a guy that worked for the city of Tucson. We spoke about NG fueled 454s (running at a low rpm, 1,200, or 1,800 on wells (which is sucking Ag water out of the ground and ruining industry). Back on track....every city park, golf course (and water hazards), every city lake, (some cover many acres) every city building, is watered with reclaimed sewer plant water. They have water left over. What do we do with it? Put in the dry Santa Cruz river? (which would be good for the river and Riparian area as it would return it closer to what it was before Turcson came along). No, that would affect the environment and putting poop-water (which is Potable) in the river might draw negatives. That won't work.....thinking caps are put on. Lets put it back in the ground (in the aquafer and then drink it).
The 1st part makes a lot of sense (not the stealing ag water part), but not so sure about the last. If we ate going to drink it anyways, why put it in the ground...OHHHHH, never mind.
