EBMUD pipeline worms way beneath estuary to improve water service and quake safety

A 3,000-foot water pipeline installed below the Oakland Estuary earlier this month will replace a 1940s-vintage cast-iron pipe that was susceptible to earthquake damage, according to officials at the East Bay Municipal Utility District.

Before being pulled through a bore hole north of Estuary Park in Oakland on April 7 and 8, the new pipeline was stretched out a half-mile along Mitchell Avenue in Alameda.
