Water Saving Tips: In the Kitchen

Water use can be direct, for example when you turn on the tap or flush the toilet. But water use can also be indirect for producing the goods and services you buy, use and consume every day (this is also known as virtual water).  

Read on to learn how to save water in the kitchen (be sure to check out our tips specifically for food and recycling), and take our Water Footprint Calculator to find out how much water you use directly and indirectly each day. 


  • Don’t let your faucet needlessly run while you’re preparing your delicious meal. You’re letting good water (and energy and money) run down the drain.
  • Install a low-flow faucet on your sink. Conventional faucets flow at around 5 gallons per minutes, while low-flow faucets flow at 1.5 gallons per minute.
  • Wash vegetables and fruits in a large bowl or tub of water and scrub them with a vegetable brush instead of using your faucet as a power-washer.
  • Think ahead! Don’t use water to defrost frozen foods. Instead, leave them in the fridge overnight.
  • Boil food in as little water as possible to save water and cooking fuel. You just need enough to submerge your pasta and potatoes. Plus with less water you keep more flavor and nutrients in your veggies.
  • Use the water left over from boiling to water your plants – just let it cool down first!
  • Put your vegetable steamer right on top of the rice, potatoes or pasta you're boiling to steam the veggies. You'll save water and have fewer dishes to wash later.

Doing Dishes

  • Get a dishwasher. They almost always use less water than washing dishes by hand, especially with water- and energy-efficient models (just make sure to only run the dishwasher when it’s full). Hand washing one load of dishes can use 20 gallons of water, whereas water- and energy-efficient dishwaters use as little as 4.5 gallons. That's a big difference if you wash a lot of dishes.

  • Scrape food from dishes into the trash rather than down the sink to lighten the burden on wastewater treatment plants. Newer dishwashers don’t even require pre-rinsing!
  • Use the garbage disposal less and the garbage more.  Or even better, compost those scraps.
  • Learn more about kitchen composting.
  • When you wash dishes by hand, don’t let the water run the whole time. Just use a little water to get your sponge soapy and wet and then turn off the faucet until you're ready to rinse a bunch of dishes at once. Better yet, plug the sink or get a tub to wash dishes in so you don't need to let the water run.

Drinking Water

  • Keep a bottle or pitcher of drinking water in the refrigerator instead of running the tap to cool it each time you want a drink.
  • Choose tap water over bottled – it takes about 1.5 gallons of water to manufacture a single plastic bottle, and plastic bottles are always made from new plastic material.
