How to water the garden without an outside water faucet!

I've come across this information on how to make your own pop bottle irrigation system for plants and find it to be interesting enough to try out.  I have a veggie garden but do not have an outside water faucet...and there lies my biggest problem. Therefore, my veggie garden relies on Mother Nature for it's watering.  Maybe by making these water/pop bottle irrigation systems and placing them throughout my garden will help!  I'm definitely going to try it and will follow-up on it's results.
