I have a ranch in Patagonia, Chile. There is a very good spring producing about 10 - 15 gal/min which is 127 ft higher than the ranch house which is 8,000 feet from the spring. At that point I want to tee off to another site which is 30 feet lower with a run of 5,000 ft. I was planning on using 2" poly pipe. Will I have any pressure at either of the ends, flow?? I was planning on building a catch basin about three feet deep at the source with a cover and a filter. Can you direct me to a plan on how to best construct it, size?
