Can hip bath and wash up dampen be used contained by the garden?
Answers: Bath water and wash up water are certain as "gray water" and as long as you haven't dumped a lot of brackish or bleach into the water, it is excellent for the garden. Be sure to pour grease and oil from your cooking pans into a soup can and discard it contained by the garbage -- i.e. not within your kitchen sink. The phosphates in the detergent may, if used surrounded by excess, cause some of your plants to get hold of a little "leggy" but if you distribute the marine over your entire garden you'll encounter little difficulty and some benefits (for example, aphids don't like it)
You'll also assist the environment by conserving water.
Good luck
Oh yes.
We have the bathtub, bathroom sink and kitchen sink draining into what's call a "field" on our front lawn at the tarn. We had the best front grassland in the rural community. The washing piece of equipment water go to a "field" at the side of the house and the lawn be great there too. The toilet drained into a cistern which was pumped out and dumped into the rural community lagoon.
