Someone posted a question in CR4 (Chat Room 4 Engineers) about siphoning water from an existing well to the surface and letting it flow downhill to an irrigation pond. The water level was 73 feet from the surface in a 6-inch diameter well casing that extended down 138 feet into the well from the surface. Most agreed that it could not be done and suggested a pump of one style or another. Exuberant corrections and contradictions helped clarify a technique that most condemned until we posted a diagram. A picture is said to be worth a thousand words.
