Grand Canyon National Park has imposed mandatory water conservation measures due to a water pump failure.
With the pump inoperable, park officials say water is not flowing to the South Rim so conservation guidelines were implemented for all consumers on the South Rim, Desert View and Hermit's Rest.
Crews are expected to begin repair work next week.
Under the restrictions, all concession operations are required to switch to disposable dishes and utensils and alter menus to use less water for food preparation and dishwashing.
The restrictions also call for serving drinking water at restaurants by request only and for lodging facilities to adopt low-water-use practices for the cleaning of rooms.
The park's utility system provides water to millions of visitors a year in addition to the 2,000 residents who live in the park.
