Water Supply
About 20 percent of the water supplied by the PCWA Water Division
is treated drinking water; about 80 percent is for irrigation
use. The Agency supplies water to customers in five geographically
established service zones:
Zone 1. Auburn to Newcastle, Lincoln, Loomis,
Rocklin, Granite Bay and Roseville, plus wide unincorporated areas.
Treated water and raw water.
Zone 2. A small residential area of 46 customers
(Bianchi Estates), southwest of Roseville, served by treated water.
Zone 3. Meadow Vista to Colfax and Alta. Treated
water and raw water.
Zone 4. Water from two wells is used to serve
the Lahontan development in the Martis Valley.
Zone 5. Irrigation water for commercial agriculture
in far western Placer County.
Treated Water
Twenty-six employees are directly involved in the production
and distribution of treated drinking water. A team of water plant
operators coordinates operation of eight water treatment plants.
Water quality personnel interpret public health laws, monitor
water to ensure its safety, perform necessary reporting to the
USEPA and California Department of Health Services. Water treatment
plant maintenance personnel maintain and repair all the water
quality facilities including the treatment plants, pump sites
and well sites. Water distribution operators route water through
pipeline systems and manage a network of tanks, pumps and pressure-control
stations.
The Placer County Water Agency operates eight individual treated
water systems. These water systems include Alta, Applegate, Bianchi,
Auburn/Bowman, Colfax, Foothill-Sunset, Lahontan and Monte Vista.
Six of the water systems are supplied through water treatment
plants that treat surface water supplied via the PCWA canal system.
The Bianchi system serves surface water purchased from the City
of Roseville. The Lahontan system is supplied by wells.
Surface water supplied by PCWA originates in the Sierra snow
pack. Sources for PCWA treated water systems include the Yuba-Bear
and American River watersheds. The source water for the treatment
plants is supplied by a network of canal systems operated and
maintained by PCWA and PG&E
The PCWA treated water systems supply over 95,000 consumers
through over 28,000 service connections.
Irrigation
About 80 percent of the water supplied annually by PCWA is used
for irrigation on the farms, ranches, landscapes, parks and golf
courses of Placer County. The Agency operates 165 miles of canals,
reservoirs and diversions to supply approximately 3,900 raw water
users.
About 2,650 irrigation water customers purchase winter and summer
irrigation water while about 1,250 customers purchase summer irrigation
water only. The irrigation season normally runs from April 15
through October 15. It typically begins two weeks later in the
higher elevation service areas around Colfax.
The PCWA irrigation water system also provides water for wildlife,
riparian habitat, fire protection, recreation and scenic beauty.
The Agency is very active in protecting watershed quality for
its source waters.
