Document Description
The Downtown Concord Water Main Replacement Project consists of replacement or abandonment of approximately 6,425 feet of existing water mains that are located in: Galindo Street between Salvio Street and Concord Boulevard; Willow Pass Road between Galindo Street and Third Street; Grant Street between Pacheco Street and Clayton Road; and Concord Boulevard between Galindo Street and Port Chicago Highway. CCWD records show that the water mains are shallow with approximately 3-feet of cover. CCWD records also indicate that there are 7 fire hydrants, 42 water meters, 19 in-line valves, and 7 tapping valves along the pipelines to be replaced. Construction of the pipeline replacements would require trenching between 4 to 6 feet in depth by 30 to 36 inches in width for the length of pipeline being replaced.
