projects is also available for viewing or download on the Documents page. |
| Orange
County, California. Orange County’s
Water Factory 21 was the first project in California
to purify sewer water to drinking water standards as
a barrier against the intrusion of seawater into a groundwater
basin. |
| West
Basin Water District, California. Online
since 1995, the district uses microfiltration, reverse
osmosis and ultraviolet light technologies to treat recycled
water for groundwater injection. |
| Los
Angeles County, California. The Water Replenishment
District of Southern California has managed the Montebello
Forebay Groundwater Recharge Project since 1962. It is
one of the oldest ongoing natural groundwater recharge
sewer projects in the nation. |
| The
Montebello Project filters an average of 45
million gallons per day of treated sewer water through
the ground into the Los Angeles Central Groundwater Basin.
The reclaimed water constitutes an average of 18.7 percent
of the groundwater supply. |
| Sanitation
Districts of Los Angeles County. The Sanitation
Districts of Los Angeles County utilize recycled water
from three of their wastewater treatment plants for groundwater
recharge. |
| San
Bernardino County, California. Recycled
water from one of the Inland Empire Utilities Agency’s
(IEUA) treatment plants is currently used to recharge
the Chino Basin aquifer at the rate of 500 acre-feet
per year and is scheduled to increase to 2,300 acre-feet
per year in the future. |
| Reno,
Nevada. The Tahoe-Truckee Sanitation
Agency Water Reclamation Plant combines conventional
activated sludge secondary treatment with biological
phosphorus removal to treat the wastewater. The treated
water is released into the Truckee River, which is the
source of the City of Reno’s water supply. |
| Las
Vegas, Nevada. Since the 1950s, secondary
treated wastewater has been discharged into the Las Vegas
Wash and represents two percent of the flow into Lake
Mead, tthe primary drinking water source for the Las
Vegas Valley. |
| El
Paso, Texas. The Fred Harvey Water Reclamation
Plant recovers and treats wastewater, which is then injected
into groundwater. The water eventually travels to one
of El Paso’s potable water fields to become part of the
drinking water supply. In 2004, a total of 577 million
gallons of reclaimed water were returned to the Hueco
Bolson aquifer. |
| Scottsdale,
Arizona. Since 1998, the Scottsdale
Water Campus has produced 12 million gallons per day
of tertiary treated wastewater that is used primarily
for use on parks, medians and golf courses. In winter,
when irrigation is reduced, 10 million gallons per day
undergo advanced purification to meet or surpass drinking
water standards before the water is used to recharge
groundwater sources. |
City
of Peoria, Arizona. The city currently
recharges 2,000 acre-feet of water per year from their
Beardsley Water Reclamation Facility. |
| City
of Glendale, Arizona. Reclaimed water
is being used directly on landscaping and being stored
in the aquifer. |
| Fairfax,
Virginia: Upper Occoquan Sewage Authority
(UOSA), Millard H. Robbins, Jr. Water Reclamation Plant.
Since UOSA came on-line in 1978 to replace 11 secondary
wastewater treatment plants that were decommissioned,
the quality of water in the Occoquan Reservoir has dramatically
improved and is generally much higher than that of the
receiving stream. |
| NEWater
Facilities, Singapore. The latest ultrafiltration/microfiltration
and reverse osmosis membrane technologies, followed by
ultraviolet disinfection, treat used water to standards
higher than the drinking water standards of the World
Health Organization and the U.S. Environmental Protection
Agency. The project has been fully operational since
2003. |
|
 |
| California
Department of Public Health. The department
provides public health services throughout California --
from maintaining safe drinking water to protecting communities
from communicable diseases, epidemics and contaminated
food. |
| California
Department of Water Resources. The department
manages the water resources of California in cooperation
with other agencies to benefit the people and to protect,
restore and enhance the natural and human environments. |
| California
Environmental Protection Agency. Responsible
for restoring, protecting and enhancing the environment
to ensure public health, environmental quality and economic
vitality. |
| California
Resources Agency. The agency restores, protects
and manages the state's natural, historical and cultural
resources for current and future generations. |
| California
State Water Resource Control Board. The board's
mission is to preserve, enhance and restore the quality
of California's water resources -- and ensure their proper
allocation and efficient use for the benefit of present
and future generations. |

 |
| Association
of California Water Agencies. From legislation,
to regulatory activity, to broad policy issues, the association
is on the front lines in Sacramento and in Washington,
DC, as a constant and respected advocate for California’s
public water agencies. |
| California
Urban Water Conservation Council. The council
works to increase efficient water use statewide through
partnerships with urban water agencies, public interest
organizations and private entities. |
| Groundwater
Foundation. The nonprofit organization is
dedicated to educating and motivating people to care for
and about groundwater. |
| WateReuse
Foundation. Thefoundation is an educational,
nonprofit public benefit corporation that serves as a
centralized organization for the water and wastewater
community to advance the science of water reuse, recycling,
reclamation and desalination. |
| Water
for Monterey County. Facing a critical water shortage, representatives
from communities in Monterey County joined together to find
a common solution. The plan resulting from their effort --Water
for Monterey County --provides a reliable, cost-effective
supply of water while safeguarding the environment. |
