Do your laundry as late in the evening as possible. Let your dishwasher run after you've gone to bed. Don't heed manufacturers' recommended usage guidelines. Replace electrical gadgets with mechanical ones. Install a low-flow showerhead and turn off the tap while brushing your teeth.
Water is a precious commodity.
You can save even more by stopping the flow when not in use. Leave cuttings as mulch to naturally fertilize your lawn. This unnecessary action not only wastes gas and adds toxic fumes to the air. It also takes its toll on your engine. Limit your additions to the landfill.
