Urine is very rich in nitrogen and according to the WHO, urine is sterile and can be used directly to the plants. I encourage every household to collect their urine and use it for the plants and at the same time saving valuable water that will be used to flush urine in the toilet bowl. For instance, in a family of 4, daily water savings can amount to 216 liters (average 3 urination per day x 18 liters water to flush x 4)! Now compute this for the whole year!!
