PHOENIX (AP) - Construction workers at the Grand Canyon have replaced more than a quarter mile of an aging water pipeline.
The nearly 50 year-old-pipeline that provides water for hikers and communities along the canyon's South Rim breaks between five and thirty times each year.
Construction on a half-mile section of the 16-mile-long pipeline began in January and is expected to be completed in July. Replacements are focused on pipeline near a popular lodge for hikers in the bottom of the canyon.
Park officials warn hikers, backpackers are trail runners that the drinking water system may be shut down along the corridor trails and recommend bringing an alternative way to treat creek water.
