A faucet that drips 1 drop per second can waste up to 1,661 gallons (6,288 liters) of water in a year! The fix is probably as simple as replacing an O-ring in your faucet, which is inexpensive, and you can learn how to change one on YouTube.
Low-flow shower heads save you around 5 gallons (19 liters) of water per shower, according to Energy Star. Just be sure you purchase a showerhead that is rated at 2.5 gallon (9.4 liters) per minute or less.
Many people just set their sprinklers to water the lawn every day, even though it may not need it. If your lawn is turning yellow, gray or spotted, then you're probably overwatering it. To save water, do the foot test. Walk across your lawn and look behind you. If the grass blades aren't popping back up after you step on them, then it's thirsty. If they do pop up, you can skip a watering. A more high-tech solution is buying a moisture detector like the AM Conservation Soil and Plant Moisture Meter or the Dr. Meter Moisture Sensor Hydrometer.
When your lawn is thirsty, only water it during the coolest time of the day and don't water when it's windy. This will help to avoid moisture loss from evaporation, which means you'll need to water less.
