Loma Prieta Earthquake—Emergency Response and Restoration: Water and Sewerage Lifelines

by Le Val Lund,

Document Type: Proceeding Paper

Part of: Lifeline Earthquake Engineering


Water and Sewerage systems performed very well with a few exceptions in the Loma Prieta earthquake. Pipeline damage occurred in unstable ground. Damage at treatment plants was due to sloshing and inverted pendulum action. Loss of commercial power affected the operation of some pumps, wells and communication equipment. Some telephone communication was interrupted by saturation at the central offices. In general, most water and wastewater emergency lifelines response plans worked well after the earthquake. Restoration was performed by agency forces or contractors. Smaller agencies were assisted in restoration by larger agencies under mutual aid.
