The San Diego County Water Authority’s Board of Directors last week approved a contract to study the viability of a new regional water conveyance system that would deliver water from the Colorado River to San Diego County and provide multiple benefits across the Southwest. The $1.9 million contract was awarded to Black & Veatch Corporation for a two-phase study. The engineering firm conducted similar studies for the Water Authority dating back to 1996 but looked at “single use” in those studies.
