Hi...
I am currently doing some
permaculture in a friend's
yard, in the southern interior of BC (Canada), where the summers can be hot and dry. (It has been 30C/nearly 90F everyday for 3 weeks and only rained once or twice). The soil is bone dry, and I am really thinking about a rainwater collection system, but here's the catch. Nobody around here uses eavestroughs (or rain gutters, depending where you live), because they get damaged with the load of winter snowfall. So I probably have to collect
water as runoff from the ground.
Would you recommend laying down a gravel bed, in sort of a trough, where the rain falls from the roof, and channelling it down towards a
swale? I could even get some piping if I wanted to channel it further away from the area into some garden beds? Any ideas? Right now there is just plastic laid down, which probably is just increasing evaporation, so it wouldn't be hard to improve on the situation.
Any suggestions appreciated!
