Hiram W. Wadsworth (1862-1939) is known as the father of
Metropolitan Water District of Southern California. As the mayor
of Pasadena, he called for a regional partnership of
municipalities to bring water to Southern California. After
initiating the Colorado River Aqueduct Association and being
elected its president, he directed the campaign from 1924-1929
that led to the establishment of the district. The pumping plant
at Diamond Valley Lake, located 90 miles southeast of Los Angeles
in Riverside County, was named the Hiram W. Wadsworth
Pumping/Hydro-generating Facility in his honor.
William E. “Bill” Warne (1905-1996) had a career for the record
books that prominently featured water issues at state, federal
and international levels.
He served under Governor Edmund G. “Pat” Brown as the second
director of the state Department of Water Resources (DWR) from
1961-1967 along with also being the first Resources Agency
secretary from 1961-1963 at the beginning of the construction of
the California State
Water Project.
Wastewater management in California centers on the collection,
conveyance,
treatment, reuse and disposal of wastewater. This process is
conducted largely by public agencies, though there are also
private systems in places where a publicly owned treatment plant
is not feasible.
Water conservation has become a way of life throughout the West,
with water demand commonly outpacing supply.
The primary reason for conservation has been drought, but now
there is increasing awareness of the limited availability of
freshwater for drinking, irrigation, industry and other uses.
Water marketing is the transfer or sale of water or water rights
from one user to another, typically from an agricultural to an
urban water agency, often without investing in new infrastructure
Most exchanges involve a transfer of the resource itself, not a
transfer of the right to use the water.
Reallocating the available water on a supply-and-demand basis is
viewed by proponents as the best financial, political and
environmental means of accommodating an increase in population.
Title 22 of California’s Water Recycling Criteria refers to
California state guidelines for how treated and recycled water is
discharged and used.
The standards also require the state’s Department of Health
Services to develop and enforce water and bacteriological
treatment standards for water recycling and reuse.
State discharge standards for reclaimed water and its reuse are
regulated by under the Water Recycling Criteria and the 1969
Porter-Cologne Water Quality Control Act–California’s regulatory
framework for water recycling.
California’s growth has closely paralleled an evolving and
complex system of water rights.
After California became a state in 1850, it followed the practice
of Eastern states and adopted riparian rights – water rights
laws based on ownership of land bordering a waterway. The
riparian property owner—one who lives next to the river—
possesses the right to use that water, a right that cannot be
transferred apart from the land.
Adjudicate -To determine rights by a
lawsuit in court.
Appropriative Right – A right based on physical
control of water and since 1914 in relation to surface water, a state-issued
permit or license for its beneficial use. Appropriative
water rights in California are divided into pre-1914 and
post-1914 rights, depending on whether they were initiated after
the December 19, 1914 effective date of the Water Commission Act
of 1913. Post-1914 rights can only be initiated by filing an
application and obtaining a permit from the state. The program is
now administered by the State Water Resources Control
Board.
California’s “Mediterranean” climate, characterized by warm, dry
summers and mild winters, is considered one of its great
attractions, but it also can be unpredictable with flooding
followed by drought and few years of “normal”
precipitation. [See also Hydrologic Cycle].
This also makes its water supply unpredictable. For instance,
runoff and precipitation in California can be quite variable.
Finding and maintaining a clean water supply for drinking and
other uses has been a constant challenge throughout human
history.
Today, significant technological developments in water treatment,
including monitoring and assessment, help ensure a drinking water
supply of high quality. The source of water and its initial
condition prior to being treated usually determines the water
treatment process. [See also Water Recycling.]
The message is oft-repeated that water must be conserved and used
as wisely as possible.
The California Water Code calls water use efficiency “the
efficient management of water resources for beneficial uses,
preventing waste, or accomplishing additional benefits with the
same amount of water.”
A watershed is the land area that drains runoff – snowmelt and
rain – into a connected system of lakes, streams, rivers, and
other waterways. It typically is identified by the largest
draining watercourse within the system. In California, for
example, the Sierra Nevada
is one of the state’s major watersheds.
The atmospheric condition at any given time or place, measured by
wind, temperature, humidity, atmospheric pressure, cloudiness and
precipitation. Weather changes from hour to hour, day to day, and
season to season. Climate in a narrow sense is usually defined as
the average weather, during a period of time ranging from months
to thousands or millions of years.
