The East Bay Municipal Utility District (EBMUD) provides potable water for approximately 1.2 million people in San Francisco's East Bay area and is constructing seismic upgrades for the portion of the Mokelumne Aqueduct No. 3 that crosses the Sacramento-San Joaquin Delta. This section of aqueduct includes three river crossings, 14.4 km of elevated pipeline and 8 km of buried pipeline. The upgrades include reinforcing the levee at the river crossings and improving the pipe joint connections for buried pipe. The $27 million project, which is expected to be completed in July 1999, will allow the aqueduct to withstand a 6.7 magnitude earthquake.
