Document Description
The SCPL is a cement-mortar-lined and coated steel water supply pipeline that was built in 1972 and conveys untreated water from the Contra Costa Canal near Clyde to the Martinez Reservoir. Figure 1 shows an aerial photo of the project area. On the eastern end, the SCPL connects to the Contra Costa Canal. The SCPL proceeds on a generally westerly course to its terminus with Martinez Reservoir. Prior to construction of the SCPL, deliveries to Martinez had to follow the portion of the Contra Costa Canal known as the Loop Canal as it proceeded south from Clyde, then looped through the cities of Concord, Walnut Creek, Pleasant Hill and Martinez to Martinez Reservoir. The approximately 28,000-foot-long SCPL consists of 42-, 48- and 60-inch-diameter pipe segments.
