Contact: Kari Cobb, 928-638-7958Grand Canyon, AZ- The National Park Service (NPS) is seeking public comment on the Transcanyon Water Distribution Pipeline (Pipeline) Environmental Assessment (EA). Public comments will be accepted for a 30-day period from today, Wednesday, October 10 through Saturday, November 10, 2018.
The purpose of the Pipeline project is to provide a reliable water delivery system to meet water supply needs at the South Rim and in the Cross Canyon Corridor in Grand Canyon National Park. The new Pipeline project is intended to support the park for approximately 50 years. The current pipeline was constructed in the 1960s, is beyond its useful life, experiences frequent failures, and requires continual maintenance to repair frequent leaks.
The Pipeline plays a critical role in supporting park operations and supplies all potable water to the park's South Rim and Cross Canyon Corridor. Water transported by the Pipeline supports more than 6 million annual visitors and approximately 2,500 year-round residents.
The EA evaluates a no action alternative and two action alternatives, which include options to relocate the water intake and replace the Pipeline in the same location. The park's preferred alternative proposes to relocate the water intake for the Pipeline from Roaring Springs to an area near Bright Angel Creek at Phantom Ranch, replace approximately three miles of the Pipeline between Phantom Ranch and Indian Garden, and construct water treatment facilities and tanks to support the water system. This would eliminate one of the Pipeline sections through "the Box" where most of the breaks occur. The proposed replacement alternative would replace the entire 12.5-mile Pipeline from Roaring Springs to Indian Garden with new pipe and no new facilities would be constructed to support the water system.
To assist the public in understanding the project and providing comments, Grand Canyon is hosting several meetings to present information on the plan. Public meetings include:
