Construction of Septic System at National Park - Mt. Rainier, WA

The work performed under this contract consisted of the construction of a new gravity septic system at the parking area for the Grove of the Patriarchs. Due to the sensitive nature of the National Park the work was to be performed in, it was not allowed to establish a work camp within the park. Additionally, all work was centered around preserving the park's natural features, and was to be accomplished in a way least inconvenient to daily operation of the park. This included erecting temporary barriers to protect all surrounding trees and natural areas, and excavation was carefully planned to avoid disturbing critical tree root zones.

Work included cutting, removing part of the asphalt parking area as part of a complete installation of all piping, piping apertures and septic tanks. A complete leach field was added to provide a complete operating septic system. The project was completed with reinstallation of the parking area, including asphalt and curb installation.
