Environmental Assessment for North Rim and Roaring Springs Canyon Water System Improvements


The National Park Service invites public comment on an environmental assessment and a programmatic agreement for water system improvements at the North Rim developed area and Roaring Springs Canyon in Grand Canyon National Park. Public comments will be accepted from March 6, 2026, until midnight April 5, 2026.

The water system improvements are part of a proposed Great American Outdoors Act Legacy Restoration Fund project called Rehabilitate the North Rim and Roaring Springs Utility Systems. The North Rim water system improvements would create a more reliable water system to meet supply needs at the North Rim and within the inner canyon between Supai Tunnel and Cottonwood Campground for a projected lifespan of up to 75 years. The existing North Rim water system is past its design life, resulting in frequent failures, extended service outages and continual repairs in a hazardous environment.

Proposed improvements include:
- Rehabilitating or replacing the waterline from the North Rim to the Roaring Springs water source
- Installing two new boreholes to house the potable and raw water lines
- Constructing a new water treatment plant on the North Rim
- Constructing additional water tanks on the North Rim and at the Roaring Springs Pumphouse
- Rehabilitating the Roaring Springs Pumphouse

Note: The 2025 Dragon Bravo fire caused significant damage throughout the North Rim developed area, including the loss of numerous buildings. Planning for the future of damaged North Rim areas will be addressed through a separate planning and NEPA process that will include public involvement and careful analysis of what reconstruction or rehabilitation options may be feasible.
