Water Savings Calculator

Answer a few questions about your indoor water use and find out how you can start conserving water today.

Do you have any water-saving fixtures in your home?

Showerheads
Did you know a low-flow showerhead uses 2.3 gallons per minute, while a standard one uses 3.8 gallons per minute? Switching to a low-flow showerhead will save 15 gallons of water during a 10-minute shower! That adds up to almost 5,500 gallons a year!
Toilets
Did you know a water-efficient toilet uses just 1.6 gallons per flush, while older standard models use 3-7 gallons per flush? Replacing your standard toilet with a water-efficient model will save as much as 19 gallons a day!
Faucets
A standard faucet uses 3-7 gallons per minute, while water-efficient faucets use as little as 1.5 gallons per minute. Installing low-flow aerators on your faucets can save thousands of gallons a year!
What kind of clothes washer do you have in your home?
Did you know a standard washing machine uses about 40 gallons per load, while a front-loading Energy star model uses just 22 gallons per load? Since the average family washes several loads of laundry a week, an Energy star model can save you hundreds of gallons every month!
How does your household wash dishes?
Did you know hand washing dishes at the sink uses about 20 gallons of water on average. An Energy star model uses just 4 gallons per load, while a standard dishwasher uses about 6 gallons per load. If you run the dishwasher only when it’s full, you’ll save even more!

Your Water Usage

Do you have a lawn or garden?
Did you know it takes 330 gallons of water to irrigate a 1,000 sq. foot lawn with 1/2 inch of water. Depending on the size of your lawn and whether you live in a dry region of the country, you could be using thousands of gallons a week to keep your grass green.

Replacing a portion of your lawn with beautiful native and California-friendly plants will save 30-60 gallons per day per 1,000 sq. ft, depending on your climate.
How often do you water?
Watering your lawn only when it needs it can add up to major savings. Water only in the early morning hours and you’ll save up to 25 gallons each time you water.
Do you have a water-efficient irrigation system?
If you upgrade to a SMART irrigation controller that adjusts water times for hotter weather and shuts down when it rains, you can save 40 gallons a day!

Also, Drip systems for trees and shrubs save 20-25 gallons a day.
Do you wash your car at home?
Washing a car by hand uses about 150 gallons of water, so washing less frequently can save big amounts of water.
If you wash your car at home, do you use a spray nozzle on your hose?
Using a self-closing spray nozzle can save 8-18 gallons of water every minute!
