A standard garden hose uses approximately 10 gallons/minute. Which means leaving on for 10-minute = 100 gallons of water.
Ways you can save water while washing your vehicle is by using water-less products, use a bucket and a hose with an automatic shut-off nozzle when you wash the car, or take your car to a car-wash that recycles.
Other ways to conserve water:
- Use a broom, not a hose, to clean your driveway, deck or patio.
- Cover pools and hot-tubs to reduce evaporation.
