In areas of the west, especially in California, homeowners will change the way they perceive their yards. As costs increase for turf, irrigation, their maintenance and water alike, the usefulness of a lawn will diminish remarkably. This will begin a new era in residential landscaping. Most parts of California receive less than 15 inches of rain in a year. Which is about half the rainfall of most mid-west states. (Average is above 30 inches per year).
A healthy, high-quality bluegrass or rye grass may require 1.25 to 2.50 inches of water per week depending on the weather and location.
Turf-type tall fescue boasts of its ability to perform well with less water than a bluegrass lawn. That is, if it can grow a deep root system. In many cases, however, the installer doesn't provide the soil prep required of turf-type tall fescue. The heavy soils don't allow it to grow deep roots, so turf-type tall fescue requires as much water as bluegrass to look good. Hybrid bermuda grass needs about 20 to 35 percent less water than turf-type tall fescue, depending on the hybrid. Buffalo grass, another alternative type, can remain green for weeks without watering, even during the hottest summer weather.
Bermuda and Buffalo grass both go brown during the cooler months and stop growing - which makes them somewhat unpopular in residential gardens (historically speaking).
CALCULATE WATER USAGE
Let’s say we are fairly conservative about using water for our lawn.
(Remember 1.25 to 2.5 inches per week is the range)
1.2 inches of water per week in the spring,
2.0 inches per week in the summer,
0.9 inches per week in the fall months.
(1.2 in/wk) (13 wk) = 15 inches of water (March 21 to June 20)
(2.0 in/wk) (13 wk) = 26 inches of water (June21 to Sept20)
(0.9 in/wk) (13 wk) = 11 inches of water (Sept 21 to Dec 20)
That's 52 inches per year!
Some Homeowner's don't even realize that they are using potable (drinking) water on the yard! However, in some areas of California, measures have been taken to help provide a recycled water source. Some Counties and City governments have been utilizing reclaimed water from sewer systems for landscaping The iconic purple pipe and purple markings are easy identifiers of this reclaimed water resource. Others are encouraging rain barrels and rain storage systems, and placing some limits on non-permeable pavement in suburban areas. The idea here is simply to catch the water from rainfall and get it into the ground water cycle and not into the storm drains.

U.S.News & World Report.
Homeowners should pay close attention to how they water their lawns and gardens to ensure that they are not accidentally wasting resources, experts say. "In many parts of the country, more than 50 percent of residential water use—that's treated drinking water—goes out on the lawn," says Mary Ann Dickinson, the executive director of the Alliance for Water Efficiency. "That's the equivalent of taking a bottle of expensive Evian and just pouring it on the grass." Experts recommend a number ways that consumers can make their outdoor water use more efficient. "When you are watering your lawn, make sure that you are not doing it in the heat of the day, so you are not losing water to evaporation," Thornton says. In addition, avoid watering the lawn when it is windy out, as moisture can be carried away from its intended destination. Finally, make sure that the water is landing only on the landscaping, and not on the driveway or street.
