Monday rainy sky, NE1 wind, thirmometer 17 degrees C, relativehumidity 80%, atmosphere 1007 hp
I completed my rain water tank. I used something plastic cases and plustic pipes to make it. it cost about 6000yen and 1 month working.
By using this system, I could keep about 150L rain water in rainy days. and I could use the water for trees,grass and flowers
in my garden at the sunny days. as I could use water without anoying about water rates, I was happy.
