After connecting to the local water system, I use my shallow well pump to water gardens, yard, etc. Figuring that may need this for the long term, I buried 3/4" white pipe to my two gardens from my lake. As one is near the house, I can also water the grass. I have used it out of reach of power some and I use a small generator to power it. If you have a water source near the plots, black plastic pipe can be bought cheaply and will last a few years, especially if you don' t subject it to much pressure. My Honda generator will run 8-12 hours on one fill and you can move a lot of water in that much time.
