Toilets in the sky. Camp Muir is one of the climber’s high camps on Mount Rainier. This site serves as an overnight basecamp for approximately 8,000 climbers seeking the summit every year, as well as a popular day hike for thousands more. The camp hosts four TTS units that were installed as an alternative to outdated systems. The park is currently in the process of building new masonry structures to house the toilets. Due to the glaciated and rocky alpine ecosystem, solid waste is helicoptered down in 55-gallon barrels at the end of each season to be properly disposed of. Waste diversion makes this  process less frequent, easier, and more cost efficient. Urine makes up a large percentage of human waste volume, so by diverting it into a drain field, the barrels fill up more slowly and do not become a sloshy mess. While climbers do a good job of complying with blue bag regulations at this high elevation, our toilets keep the waste at base camp contained, even with the cold, extreme conditions. There’s a reason why Rainier is implementing our systems all throughout the National Park.
