Grand Canyon National Park has upped water restrictions for the South Rim after a new break in the Transcanyon Waterline.
Officials on the ground are looking to prevent a public drinking water shortage and preparations are being made for further escalation, such as a dry campground and no overnight hotel guests.
Water spigots at Mather Campground have been turned off, and camper services closed.
Officials ask visitors and residents to do everything possible to conserve water by taking short showers and turning the faucet off while shaving or brushing their teeth.
Backcountry hikers should carry sufficient water or a way to treat it.
Restrictions initially went into effect last week after a previous pipe break.
The pipeline supplies water to the Grand Canyon's South Rim and inner canyon. Construction of a new $208 million waterline is scheduled to be completed by late 2027.
