Flash flooding causes major damage to the Grand Canyon’s critical water pipeline

The sole pipeline that supplies water to millions of visitors at the Grand Canyon was severely damaged by flash flooding over the weekend, complicating a yearslong repair project. Grand Canyon Deputy Superintendent Brian Drapeaux expects a significant portion of the pipeline, estimated at miles, to be destroyed. From aerial surveys, park officials estimate that around 40% of the 12.5-mile (20-kilometer) long Transcanyon Waterline was impacted.

The pipeline, which transports water from one side of the canyon to its base across a bridge and back up the other side, has experienced numerous breaks over the past decade. A more than $200 million repair and replacement project was already underway when the recent floods struck. Due to the extensive damage, the park has implemented water conservation measures, including short showers, avoiding running water while brushing teeth and selectively flushing toilets.

The pipeline upgrade project, initiated in 2023, aims to move the water intake further down the canyon to Bright Angel Creek, closer to Phantom Ranch, a popular lodge at the base of the canyon. The project, which began in 2023, involves installing helicopter pads, constructing water treatment facilities and replacing several miles of pipeline.
