CCWD Overview
The Contra Costa Water
District (CCWD) serves a
population of about 450,000
people in north, central and
east Contra Costa County.
Formed in 1936 to provide
water for irrigation and
industry, CCWD is now one
of the largest urban water
districts in California and a
leader in drinking-water
treatment technology and
source water protection
About 250,000 people receive treated water directly
from CCWD, and the other 200,000 receive water the Water District delivers to six local
agencies. CCWD draws its water from the Sacramento-San Joaquin Delta under a
contract with the federal Central Valley Project (CVP), and as such is particularly
concerned about Delta water quality and the Delta environment.
CCWD is the CVP's largest urban contractor. In 1998, the water district completed
construction of the locally-financed $450 million Los Vaqueros Project, including a
100,000 acre-foot reservoir, designed to provide improved water quality and energy
supply reliability for CCWD customers as well as net environmental benefits.
Multi-Purpose Pipeline (MPP)
Project Summary
The pipeline is called multipurpose
because it can serve
treated water to both the treated
water service area and Contra
Costa Canal in the event of a
canal outage/emergency. In the
event of a regional disaster, such
as a large earthquake, the
pipeline is also designed to
connect up to one of the district's
raw water sources to provide water for fire fighting. The MPP's primary purpose is to deliver water west from the
Randall-Bold Water Treatment Plant in Oakley to the District's existing treated water
distribution system in north Concord.
By supplying treated water to
Central County, this pipeline will
free up capacity in the Contra
Costa Canal to meet the needs of
Antioch, Pittsburg, Bay Point, and
Martinez into the year 2020. The
project also includes several
features that will bolster the
efficiency of the canal. In the event
of an emergency, the new pipeline
can serve as a backup to the
canal and treated water from the
Bollman Plant in Concord could be
transported to residents in East
County.
The District awarded construction
contracts for the $115-million
project on April 18, 2001. C.W.
Roen Construction built the
Treated Water Pump Station
project and Steve P. Rados, Inc.
installed the pipeline and raw
water system improvements.
Ameron International's Water
Transmission Group received an order from Steve P. Rados, Inc.
for supplying the pipeline for the MPP Project and specifically the entire 42-inch
diameter pipe. Ameron's Tracy, CA plant manufactured and delivered over 110,000
linear feet of Cement Mortar Lined and Mortar Coated Steel Pipe to the Standards
of AWWA C200 and C205 as specified by Montgomery Watson Harza (MWH), the
engineering consultant. The 21-mile treated water pipeline construction began on Dec.
19, 2001 and the last piece was installed on May 29, 2003. Soon afterward, the pipeline
and pump station began testing before entering regular service in September 2003.
