GCPBA RiverNews 1/7/2016 - Grand Canyon in Depth: Pipeline on the Precipice
The Trans-Canyon Pipeline was built in the late 1960's and supplies all of Grand Canyon National Park's drinking water. From its source at Roaring Springs on the North Rim, water travels 15 miles through an aging pipeline to reach the South Rim of the park. Over the past decade the pipeline has suffered numerous leaks, fissures, and breaks. Full replacement of the TCP is currently estimated at around $150 million.
"Guaranteed water to the South Rim is in peril as long as we have the existing pipeline and infrastructure in place. If we don’t have that, then everybody goes home." Grand Canyon National Park Superintendent, Dave Uberuaga.
During 2015, workers at Phantom Ranch replaced 2,800 ft. of the 15 miles and that cost the park 3.5 million dollars. To replace this part of the pipeline, the contractor had 121,500 pounds of steel pipe flown in. The work required some temporary shutdowns of the drinking water system along corridor trails, and hikers and Phantom Ranch guests experienced noise and dust during the construction.
Multiple breaks along the pipeline in late June 2013 required the closure and evacuation of guests and employees from Phantom Ranch.
