Mount Rainier National Park Archives Photo of Edith Creek Chlorination House.
The Edith Creek Chlorination House is a small building built in 1930 that served as part of the water supply system for Paradise. Constructed to withstand extremely heavy snow loads, the building’s low-pitched gable roof of reinforced concrete measures 8 inches in thickness topped with 4.5 inches of slate. Located on a gently sloping hillside above Edith Creek, native stones were used to veneer the exterior walls to help blend the building with the subalpine environment.

The Chlorination House is a contributing structure in the Mount Rainier Historic Landmark District along with the nearby Edith Creek Dam. It is also listed on the National Register of Historic Places as an example of NPS rustic architecture as well as for its association with park engineering. The area around the Edith Creek Chlorination House still provides water to Paradise and is closed to public access, but it can be easily viewed from the nearby Golden Gate or Alta Vista Trails at Paradise.
