Calculate Your Water Consumption
According to the U.S.D.A., basic indoor water consumption per person is 50-70 gallons per day. You can calculate what your average indoor water consumption should be by taking the number of people in your household x 50-70 gallons per day. Since outdoor watering is done during the summer months, you might want to calculate and compare with winter water use. If your basic indoor use is high, you should check for leaks or consider replacing some of your plumbing fixtures with new low-flow devices.
Water Saving Kitchen
Each dishwasher load uses 14-20 gallons of water, depending on the brand and size. To save water, wash only full loads. Installing a low-flow aerator/sprayer on your kitchen sink faucet will make washing/rinsing dishes easier and save water.
Water Saving Bathroom
Consider installing low-flow aerators in your bathroom faucets. You can save up to 3.5 gallons per minute of water.
Car washing Tips
When washing your car, use a pistol-grip nozzle, one that shuts off when you let go of it. You will reduce your water use per car wash from 200 gallons down to 20 gallons if you don't let the water run.
The greatest waste of water comes from applying too much and too often – much of the water is never absorbed. Instead of watering for one long session, water a few times for shorter periods and take 15 minute breaks between each session. This will allow water to soak in while minimizing runoff.
You can reduce your lawn's water requirements by cutting it taller. Bermuda can be cut 1" deep, Bluegrass and Rye grass can be cut 2"-2.5" deep, and Fescue can be cut 2.5"-3" deep. If your lawn gets a lot of traffic you probably will need to water and fertilize it more to promote strong growth in worn areas.
