Gray water is wastewater generated from household activities like bathing, showering, and doing laundry. While gray water is not potable and should not be used to drink or on fruits and vegetables you consume, there are many ways to capture and reuse gray water.

• Kitchen or bathroom sinks: Fill empty jugs as you’re waiting for tap water to warm up. This water can be used to clean up around the kitchen or bathroom.
• Pasta water: After boiling pasta, vegetables, or eggs, let the water cool and use it to water your houseplants. Make sure there's no oil or salt added.
• Laundry water: Put a bucket in the sink to collect washing machine water. You can use the water to wash a car or mop your floors. If you’re using eco-friendly, garden-safe detergents, you can use the water for your garden or lawn.
• Shower water: While waiting for the shower to warm, place a bucket under the faucet to catch the cold water. Use this water for cleaning or watering your plants.
