Building our own rain water harvesting system

When you live in an area with lack of water, you do everything you can to use the water in the best possible beneficial way. We build our own rain water system, with a 10.000 liter tank in the ground, and 2 containers of 2.000 liter for the irrigation of the greenhouse. For this we used 2 recycled containers (used for food.- so no harmful), and a lot of pallet wood. We had to buy the gutters and pipes, and pay a little bit for the containers, but overall, we saved a lot by doing it this way.
