“Water, water, everywhere, nor any drop to drink.” That phrase could have been San Diego’s motto before the First San Diego Aqueduct. Today we’re standing near a vital artery of this city. It’s the First San Diego Aqueduct.
Let’s dive into the story of how this aqueduct came to be. San Diego experienced rapid growth during World War II. The city’s population doubled. Water use also doubled. Local water sources were strained. A reliable supply from the Colorado River became essential.
The U.S. Navy stepped in to help. They agreed to construct the aqueduct. The City of San Diego would repay them later. Construction began in 1945. It was completed in 1947.
Imagine the relief when the first Colorado River water flowed into San Vicente Reservoir. On November 28, 1947, that dream became a reality. The water traveled 71 miles. It flowed from the Colorado River Aqueduct in Riverside County. This marked the end of San Diego’s total dependence on local water.
The First San Diego Aqueduct is composed of two parallel pipelines. These are Pipelines 1 and 2. Pipeline 1 was finished in 1947. Pipeline 2 followed later. It was completed in 1954. These pipelines run 70 miles south. They stretch from near San Jacinto to San Vicente Reservoir.
The aqueduct wasn’t just a simple ditch. It had to cross some tough terrain. There are seven tunnels along the First San Diego Aqueduct. These tunnels range from 500 to 5700 feet long. The total capacity of the First Aqueduct is 196 cubic feet per second.
Later, the Second San Diego Aqueduct was built. It added even more capacity. Today, the San Diego Aqueduct system supplies about 70 percent of San Diego’s water. The San Diego County Water Authority maintains the aqueduct. They ensure a safe and reliable water supply.
Think about the engineering marvel before you. The First San Diego Aqueduct secured San Diego’s water future. It allowed the city to flourish. The aqueduct remains a testament to the ingenuity. It shows the cooperation that shaped this region.
