<br /> In 1929, Los Angeles County began using recycled water for landscape irrigation in parks and
<br /> golf courses.9
<br /> In 1967, the Irvine Ranch Water District(IRWD) began recycling water at its Michelson Water
<br /> Reclamation Plant. In 1991, IRWD became the first in the nation to obtain health department
<br /> permits for the interior use of recycled water for flushing toilets and other non-potable uses."�
<br /> Current Use of Recycled Water
<br /> Californians use recycled water for a variety of purposes including irrigation, toilet flushing,
<br /> construction, water features, dust control, cooling and air conditioning, soil compaction,
<br /> commercial laundry, car washing, fire sprinkler systems, and sewer and street cleaning.
<br /> (Appendix C)Recycled water must not be used for drinking, bathing, or swimming pools!
<br /> In addition to commercial customers, residential customers are increasingly using recycled
<br /> water. In southern California, virtually all new residential development serviced by the IRWD
<br /> are required to use recycled water for landscape irrigation. In northern California, Vintage
<br /> Greens in Windsor is equipped with dual piping that enables homeowners to use recycled water
<br /> outside and potable water indoors."
<br /> At sites using recycled water for irrigation, signs are displayed warning people not to drink from
<br /> the irrigation system.

<br /> Some local governments, such as Los Angeles and Orange County, are using recycled water for
<br /> indirect, potable groundwater supply augmentation. The recycled water is pumped into
<br /> groundwater aquifers, is pumped out, treated again, and then finally used as drinking water. The
<br /> term for this process is "groundwater recharging."12
