The National Park Service is installing new water bottle refilling stations throughout Grand Canyon National Park to help reduce the use of disposable water bottles. The six South Rim filling stations are located at Hermit's Rest, Bright Angel and South Kaibab Trailheads, and two visitor centers - Verkamp's and Desert View. Three North Rim stations will be at the North Kaibab Trailhead, the North Rim Visitor Center, the the North Rim Backcountry Office.
According to the park's Chief of Facilities Management, Tim Jarrell, "The amount of litter associated with disposable water bottles has been increasing along park trails and walkways, it's one of the major contributors of trash below the rim, and it's currently estimated that disposable water bottles make up as much as 30 percent of the park's solid waste stream."
The water pouring from the new filling stations is pure, clean, Grand Canyon spring water and is available for free, which is nice. In fact, it's probably the only thing that's available for free in the entire park.
