Last year in foothills North Carolina, we had a hundred-year flood in June. Then we went three months without any rain at all. Some things produced well in spite of drought, but tomatoes really suffered and I hardly got any pumpkins. I was not able to keep things adequately watered by hand even before my catchment tank ran dry.
I know that the carbon footprint of tap water is pretty small compared to, say, tropical vacations. But I still have a philosophical problem with paying to have water cleaned so thoroughly that it’s drinkable, and then pumped for miles and miles, only to pour it on the ground. I like the idea of living within the rain budget of my area, which isn’t too hard because we usually get too much. I like the idea of having irrigation water even if I lost access to my local water utility for some reason (power outage, income outage, anything).
Most of all, I like the idea of my garden looking all big and lush like my mom’s. She waters constantly.
So, this spring I added a second catchment tank to our little house, and one to the new pole barn up by the orchard. Big irrigation tanks cost hundreds or thousands of dollars, but I can get a used IBC tank for about $45. I’ve now set up five of these tanks, and I feel it’s a relatively easy and cost-effective option for small-scale irrigation.
This is my Dad’s very nice setup, which I helped him install as a fun Mother’s Day project. Don’t worry, this photo was taken before completion, and the final installation does not include painter’s tape.
