How big is the cistern?? and you need put some sort of chem system in the line, like for a swim pool?? but obviously less and different kind of chems??
try to dig another well?? I had my little 30' well irrigation well go dry, so I tried messing with it, but too much bother....it used to provide the heat sink for the HVAC a water to air type unit, but just no outside condenser coils.....nice large coils special wound, so freon in middle, water jacket outside....krazy plumbing as you can imagine.....but when it came down to it, a better air/air unit outside runs actually cheaper than the old water/air unit that came with the house....so we just rely on rain to make the grass grow, and it certainly been growing like MAD this year.....
