Pipe break floods road with 250,000 gallons of water, knocks out service

A sudden break in a downtown water main last week sent some 250,000 gallons of water and mud coursing down Belvedere’s Cove Road into garages and homes, demolishing landscaping adjacent to the Old Rail Trail and knocking out water pressure across much of the southern peninsula. The Sept. 25 break occurred in an 8-inch cast-iron water main that was installed in 1949 and required a 17-foot section of damaged pipe to be replaced. Water roared out of the break at 2,000 gallons per minute from where Lagoon and Cove roads meet at the entrance to Belvedere across from the Belvedere-Tiburon Library. It rose to about a foot above street level at one point. (Elliot Karlan photo / For The Ark)
