Title: | Contra Costa Water District Shortcut Pipeline Improvements Project |
---|---|
Summary: | The Shortcut Pipeline (Shortcut) is a cement-mortar-lined and coated steel water supply pipeline built in 1972 to convey untreated water roughly 28,000 feet from the Contra Costa Canal to the Martinez Reservoir in north-central Contra Costa County, California. The pipeline consists of 42, 48 and 60 inch-diameter pipe segments and associated appurtenances, including valves for sealing, draining, and refilling of the pipe, monitors to detect settling, and a cathodic protection system to prevent corrosion. The Proposed Action will construct five primary segments of new access roads within Reclamation right-of-way (ROW). These roads are needed to access and maintain a number of valves along the pipeline ROW. Once access to a particular valve is available, new valves would be installed if needed or existing valve would be repaired. The pipeline would be inspected where the break occurred in 1989 at Site 4 and the break in 2013 by the Town of Clyde within Site 10. If deficiencies are found, pipeline sections may need to be repaired through slip lining, spot repairs with minor excavation, or by trenching and replacing entire sections of the pipe. |
