Editor, Manteca Bulletin, I have two suggestions that I think make a lot of ‘common sense’ — the first is something my husband and I saw while traveling in Far North Queensland, Australia. In the public bathrooms the toilets were just like ours with one very good, practical and simple difference —there were two buttons on top of the water tank, one was black and the other white. Black was used for a ‘full’ flush while white was used for a smaller flush, simple and it saved water.
