to answer my own question, i'm installing some rainwater catchment barrels at my house hopefully this week. all but one (we have four) were sourced from local folks. once these are installed, i have purchased a zero-pressure drip irrigation system and am going to try to have that installed before the first big frost, usually about two or three weeks from now where i live. there won't be any water in it this season, but it will be ready to go in the spring - or so i hope!
