Earl Thomas Prestressed-Concrete Reservoir Is World's Largest

摘要

The he largest prestressed-concrete reser-voir in the world was recently constructed at San Diego's Alvarado Water Treatment Plant (WTP). The reservoir replaces a 50-year-old, 35 million gal (132 million L) reinforced-concrete and earthen dam reservoir that had been unusable for the past decade because of cracking, seismic instability, and inadequate water circulation. The new, partially buried reservoir is to be surrounded by palm trees and have a road across its roof.
