Pumps, Wells, Tanks, Controls / low yield well with storage tank
« on: May 24, 2011, 04:13:12 PM »
Hello everyone. I'm setting up an irrigation system for a 0.5-acre lot with conventional landscaping (lawn, etc.) as well as a large vegetable garden and about 50 grape vines. The lot has an irrigation well that produces only 5 gpm and I want to add a 1500-3000 gal cistern with a booster pump for extra storage. I plan to run the submersible well pump at night to fill the cistern and a booster pump during the day to irrigate. The cistern will be located about 100' away from the well and 4-6' higher in elevation. The booster pump will be located at the well. The system will only be used for 6 months/year, during the dry season in California.
I'm putting the trenches in now but won't be installing the cistern until next winter. I'd appreciate any advice on the design. For instance, what type of wire should I put in the trench now for float valves and other controls at the cistern? Is 18 or 22 gauge sprinkler control type wire adequate? How would I calculate the smallest size pressure tank for use with the booster pump? The pumps will be running off a 240V circuit that I'm bringing from the house to the well, a 50' run.
Thanks.
