Recycled water is wastewater that has been processed through primary, secondary and tertiary treatment and disinfected with chlorine. Man-made water recycling, also known as water reclamation or water reuse, centers on using treated wastewater. Recycled water, also known as "greywater," derives from residential water uses such as the bath, shower, washing machine, sink etc. Across the globe, 2 out of 10 people do not have access to safe drinking water, and in the U.S., many states face water shortages and droughts. In the U.S., we spend billions of dollars treating water to drinking water quality when we use only 10% of it for drinking and cooking, then flush most of the rest down the toilet or drain. All water is recycled and reused as a part of natural water processes such as the hydrologic cycle. Recycling wastewater can extend water supplies, improve water quality, reduce discharge and disposal costs of wastewater, and save energy. Using recycled water reduces reliance on scarce and expensive surface water. It can also minimize groundwater overdraft and reduce discharges of treated wastewater into rivers and oceans. Reduces the need to import water over long distances or pump our limited groundwater supplies

STATE PERSONAL
+ Install a gray water system in your home.
+ Catch fresh water from shower for reuse
to water plants.

+ In California, water recycling is a critical
component of the state’s efforts to use
water supplies more efficiently.
+ The state presently recycles about
714,000 acre-feet of water per year and
has the potential to reuse an additional
two million acre-feet per year. Water
management officials in the state are also
shifting away from construction of new
dams and reservoirs, making water
recycling increasingly important.

9. The city of Los
Angeles gets the
majority of its water
imported.
Owens River,
Northern California
Colorado River
Imported water is
extremely expensive.
It is time for Los
Angeles to focus
more on local water
supply.

10. California Drought
+ The entire state of California is experiences
drought conditions. In Los Angeles Country,
100% of people (9,818,598) are affected by
drought.

13. CONS
+ Expensive
+ Personal greywater systems can be expensive.
+ Distrust
+ Many people do not understand the filtration
process

14. Water Recycling
Going Forward
Efficient water use is critical. In the face of
high demand and a limited supply, water
recycling is increasingly common
throughout California. Already, some
parts of the state recycled water meets
approximately 7 percent of water supply
demands.
The California State Legislature also aims
increase the use of recycled water.
