Even though we have a well, the idea of water conservation still appeals to me. Up until this thread, though, I haven't seen an idea that really appealed to me. I already have a submersible pump that came with the house that I've used to drain the basement over the years. I'm considering using it in conjuction with a large disused cistern alongside the house that is usually about half full of water. The cistern water should be about the same temp as the well water, which is ground ambient, about 55F. Submerge the pump and run a length of hose to my brew area. If I put another hose fitting on the discharge hose on my immersion chiller, I could even recycle the water to the cistern....but I see no reason to do that, I'll probably just fill 5 gallon buckets and haul them onto the garden as the wort chills. Just another example of the great ideas that come up on these forums!
