<p>The water well operating system draws water out of a first well during a first phase, enriches it with oxygen, and delivers it to a second well, so as to precipitate materials in solution from the ground water round about. The supply or enriched water to the second well is then halted, and in a second phase enriched water is drawn off for domestic consumption. The functions of the two wells are periodically interchanged, part of the water drawn from the second well during the second phase being enriched with oxygen and delivered to the first one until the water round the latter has been prepared, water being then drawn from it for consumption.</p> |
