In this one-hour presentation you will learn about the latest innovations in water conservation technology, along with tried and true methods for saving water. To frame the discussions, we will discuss where the Valley of the Sun's water comes from and how much water we actually use.

Indoor plumbing technology as well as federal standards since the 1990s contributed to major improvements in efficiency of water use indoors. We will discuss the Environmental Protection Agency's WaterSense product labeling program for high efficiency and high performing water-using devices (similar to Energy Star for appliances) and how such technology has helped reduce water demand. For example, "over the 20 year period from 1994 through 2012, the City of Phoenix's average per person water usage dropped 25 percent. The total water produced by Phoenix for its customers in 2013 was the lowest it's been since 1995, in spite of a 30 percent increase in population (340,000 people) during the same period of time" (source).

Though indoor water use is often the most recognizable form of water use, indoor water use in the Phoenix Metropolitan Area accounts for about only half of a household's water consumption. The other half (and sometimes as high as 90%) of the water use at a household is devoted to outdoor uses, such as landscape irrigation. Due to the behavioral action of outdoor watering, outdoor water consumption remains high, despite advances in technology. The same can be said for commercial facilities. Smart controllers and other technologies such as pressure-compensating drip emitters and stream rotor sprinkler nozzles have the potential for water savings- but it is still up to the human irrigation programmer to input the correct settings for proper watering. We'll discuss how to irrigate efficiently in the desert for optimal plant health.
