Living off the grid - homesteading and self-sufficiency

Yeah, the only part of Europe we could afford was dry af so we only have rainwater, and in the past couple of years it's hardly rained at all. We do collect from every single roof we have, we can store just over 11.000 litres (~3000 gallons) but if it doesn't rain there's nothing to store. after 5 years we're just about ready to dig a well or move but we can't afford either :) we're doing okay though, we have water in the house and all our animals have enough to drink - the one thing we're missing is irrigation for a veggie garden. so mostly we grow vegetables in winter.
