"Help The Planet, Save Money & Brag About It"

What forms of irrigation best conserve water?  I think that drip-lines would be among the top, in addition to computer-controlled sprinkler systems that turn on/off based on the weather.

Here we are allowed to water only one day a week for only so long between certain times.  If we are caught watering outside those times, then our water is turned off and we get a hefty fine.  There are other restrictions too.  That’s a pretty good deterrent.

I read a book called Gaviotas, which was about a self sustainable community in columbia. Anyway, they had a very ingenious and supper simple irrigation system.

Basically it was a drip line type system made out of clay.
They burried clay tubes with small holes in the sides. These holes would swell shut when the ground and the clay was moist and when the ground was dry the clay would dry up and srink allowing water to pass through the holes.
This is a totally passive system that naturally irrigates when the ground needs it.

Anyway, just wanted to throw that out there because I always loved that idea.

Just goes to show no matter how much technology you have at your fingertips, sometimes the best ideas and the simplest :wink:

Drip-lines are fairly effecient whilst computer-controlled sprinkler systems will ensure that water is not used unnecessarily whilst ensuring that the ground remains moist enough to sustain any plant life.

I’d read about one or two other rural communities that used very fine channels to supply water across a vast area which really made the most of what little water falls there.

I would like to the best method for water conversion.

I also want to know some ways to conserve water. We should learn how to conserve water coz it will really help in the global warming that the world is experiencing right now.
