Choose a washer with load size selector and variable water level control. Install water saving devices outside. Use a nozzle that can be shut off or adjusted to a fine spray. When finished, shut off at the house instead of at the nozzle to avoid leaks. Consider a water saving drip irrigation system that provides a slow, steady supply of water to garden and shrubs.
Warm weather means more outdoor activities, and more outdoor water use.
Be as careful and efficient outdoors as you are inside the home. Presoak grills and oven parts overnight, then wash with an abrasive scrub brush or pad and use plenty of elbow grease to minimize water use. Check faucets and hose connections for leaks. Repair or replace when necessary. Inspect pipes for pinhole leaks.
