aqueduct

The turmoil in Istanbul played out in the shadow of a Roman aqueduct.

The tunnel would create a second route to transport water to the south side of the Delta, where pumps send it into the aqueducts of the State Water Project and onward to cities and farmland.

“They go through the aqueducts or other exits and someone could be waiting for them,” Obayashi said, adding that police often don’t have time to react and set up a perimeter.

Massive aqueducts transport water through deserts, farmlands and mountains to sustain 19 million people across six counties.

In the early 20th century, Los Angeles built a massive aqueduct to take water from the Owens Valley and soon dried up Owens Lake.
