How to save water when washing your hands

Whenever you do work that involved getting your hands dirty, make sure that you have done all your work before washing your hands.
If you need to wash your hands before doing similar work again, don't wash your hands at all.

Make sure all your work is done before washing your hands. If you wash your hands after each chore, you are wasting water so to help conserve as much water as possible, make sure all the work is complete and only then wash your hands.

If you need to wash your hands in between chores because it's necessary for a specific chore such as child care, cooking food with your hands etc. then do so. But even then try to finish all the dirty chores before moving on to the cleaner chores.

All this helps conserve water.
