Urine – In ‘developed’ counties, urine is relatively ‘benign’ and would not normally contain bad diseases, parasites etc. On this basis, it can be emptied almost anywhere that other people don’t walk, play etc. Grass verges, under hedges, around tree bases stored and diluted as an excellent fertiliser. Of course you can always pour it down toilets, drains or Elsan points too. If you are using strong medications then be more careful where you put it and don’t put it around fruit bushes, trees etc. Composting urine with the poo is more likely to neutralise the chemicals as microbial action is very effective.
